In this first part Armadas C4ISR editoranalyses the technologies and toolsrequired to build the foundation layer ofcurrentnetwork-centric operations.

Thedigital agehasbrought anewhorizonto geomatics. The word, coined in French-speaking Canada in the early 1980s,describes the contribution of digitaltechnologies to environmental survey andanalysis; geomatics encompass surveyingand cartography, but also photogrammetryand remote sensing, as well as Geospatial

Information Systems (GIS) and GlobalPositioning System (GPS) technologies.

One could have thought that after a fewcenturies of charting, surveying the Earthwas nearing to a close.Quite to the contrary,this endeavour is permanent, as ourenvironment continuously evolves (think ofice caps, coastal areas, or deforestation), andman adds new features to topography.Mostimportantly, requirements for accuracyhave soared, as precision navigation andguidance open new dimensions in fine-

I DATA COLLECTION: ACCURATEAND AGILE SENSORSWhile surveying trade has not disappeared,the surveying tools have changeddramatically. Todays military topographicteams thus deploy with state-of-the-artground sensors and software. Groundmeasurement sensors gradually integratelaser technologies forhighlyaccurate ranging;but thevery locationofmeasurementunits is

immensely enhanced by the latest globalnavigation satellite systems, like GPS andGlonass, and since 2014 their European andChinese equivalents, respectivelyGalileoandBeidou constellations. In some areas of theworld,differentialGPS(DGPS)servicesallowpinpoint ground location; the latestgenerationofTrimblePro series receivers, forexample, subscribe to Egnos (EuropeanGeostationaryNavigationOverlayService) toofferuptosub-meteraccuracy,whileensuringmaximumuseof available satellites and someresistance toatmospheric andenvironmentaldegradations. The resultingmeasurement ofground control points, essential to

topographic surveyandmapmaking, isnearlyerror-free.USArmyengineering topographicsurvey teams thus deploy with the NorthropGrumman Enfire kit, which gathers opticaland laser rangefinders and military GPSreceivers around data collection, storage andexploitation devices integrated with map-productionsoftware.

In hostile or remote areas though, thedifficulty to access groundsecurely, aswell asmultiple perturbations brought by groundcover(foliage,buildings)has ledthemilitary todevelop remote sensing since the 1940s. Thefast development of aerial photographyallowedcapturingvast expensesof seaor land,and multi-point triangulation techniquesprovided accurate location free fromgroundinterference. In addition, oblique or stereoimagery brings information about terrainelevation. Today, the proliferation of sensorsand digital image processing technologieshaveboostedphotogrammetry, openingnewgrounds for data integration across theelectromagnetic spectrum, combining laser,infrared, optical and radar wavelengths forunparalleled capture of terrain data in day,night and above clouds. The Swiss LeicaGeoSystems is famous for its airborne imagingsensors. The Leica ADS80 airborne digitalsensor offers a high-resolution mode fororthophotoproduction,with swathwidthsof24000 pixels. It comes with a flightmanagement and control system software,computing aircraft dynamics against asoftware sensormodel tominimise flight andatmosphericdistortions.Multi-triangulationmeasurements determine where the camerawas in x, y and z and when the picture wastaken, to automate production of largemosaics of surface travelled.

Videooffersvariousadvantages, fromlow-cost sensors to real time availability of sensordata. Simactive, aFrenchCanadiandeveloperof photogrammetry software since 2003, hasthus recently unveiled a new version of itsCorrelator 3D photogrammetry producttailored for small-format drone sensors. Butthe ultimate refinement of aerial remote

sensing has come from active sensors in thenon-visible range; lidar (LightDetection andRanging) provides a laser-based scanningmethodof theEarth surface especially suitedto characterising micro-elevations. Initiallydeveloped tomeasure forest canopyorcoastalerosion, lidarhasbecomeaprimary sensor togenerate Digital ElevationModels (i.e. Earthelevationaugmentedbyvegetationcover andman-madeobjects).

Overhead surveillancehas benefited fromrecent progress in digital video sensors,producing Full Motion Video (FMV) withincreasingly sharp resolution and extensive

metadata, including geolocation. Dedicatedfull-motion video exploitation productsleverage video metadata, correcting errorsinherent tomovingvideocollectionplatformsto produce mapping and targetinginformation. The recently-established 2d3Sensing enables analysts to provide tie points(geo-located reference points) betweencollected imagery and a reference map. Foreachvideoframe, thesensor-agnosticsoftware

can display the platform position and flightpath, but also where the camera points.Additional telemetrydataprovides locationofevery pixel, thus producing geospatialinformation usable for intelligence ortarget acquisition. Together with ESGElektroniksysteme, 2d3 has delivered to theGerman BundesMarine a motion imageryprocessing, exploitation and disseminationsystemintotheirNorthropGrumman/AirbusDefence&SpaceEuroHawkhaledrone, flyingmaritime patrol missions. Harris provides asimilar capability with its Fame (FMVAssetManagementEngine)whichcollects, indexesanddisseminatesvideofrommultiple sensors,without the same fidelity ingeoregistrationatthe frame level, though.

The space age has brought overheadimageryandremote sensing toanewaltitude.Since satellite images are less prone toatmospheric interference and havepredictable distortions along orbital path,space reconnaissance has become thepreferred way of collecting data about hugeterritories worldwide, free from airspacesovereignty. The early remote sensingsatellites of the 1960s were thus the mostvaluable strategic asset to map adverse

Tasking multiple space sensors through weather, terrain, and time zones while maintainingoptimal ground control requires dedicated planning and optimisation software, such as theproven CPAW used by commercial and military operators worldwide (OrbitLogic/Google Pro).

territory and manage crises, until digitalcameras and commercial satellites broughtthis capability to the larger public. The USNational Geospatial Agency began to placelarge contracts to commercial imagingsatellites, until cost dropped in 1999 whenLandsat satellitedatahadcopyright removed.Google began to democratise space mapsfrom the mid-2000s, initially from the 30-metre resolution, multi-spectral bandThematic Mapper of the Landsat imagingsatellite, followed by higher resolutioncommercial satellites: Ikonos (the firstmetricresolutionsensor),QuickbirdandWorldviewsub-meter imagers from Digital Globe, orGeoEye (bought byDigital Globe in January2013),whichnowpopulateGoogleEarth.Butspace remote sensing was considerablyenhanced by synthetic aperture radars, withimaging capabilities for day, night and all-weather. Its lower resolutionandsensitivity toelevations made radar imaging satellitesprimecandidates for thegenerationofdigitalterrain models, a powerful enhancement tolegacymapbuilding.

The main European challenger, SpotImages (nowAstriumServices), has a similartrack record of exploiting multiple satellitesin synergy, with increasingly higherresolutions which beat Landsat imager longago. The current constellation advertised byAstrium combines dual-use Spot 6 and 7satellites with the latest-generation Pleiades1A and 1B. The four satellites operate in lowpolar orbit as a constellation, phased 90

apart, offering a daily revisit time. Pleiadesuses a particularly agile Astrium platform,built around the powerful Thales AleniaSpace telescope todeliver 0.5-metre accuracyinblackandwhite.Thanks to three collectionplans a day, imagery acquisition time is lessthan 24h, while the satellite manoeuvresaround its axis in seconds to capturemultipleimages in strip, stereo or spot modes. SpaceImaging is catchingup fast,with the additionof Worldview-3, launched in August 2014;this 29-band very high resolution sensordelivers 0.3-metre resolution imagery withatmospheric correction (smoke and hazereduction). It is adding to the Digital Globeconstellation of WorldView, Quickbird,Ikonos andGeoEye imaging satellites. Since2013, a partnership with Skybox imagingtriggers the first application of videosurveillance from satellites. The start-up haslaunched its 2ndSkysatmini-satellite in2014,withhigh-definition still andvideo imagery;such a disruptive technology will challengelegacy space imageryproviders.This race forresolution and coverage will receive a boostfrom the release of resolution restrictions bythe US Department of Commerce, from50cm to 25cm from June 2014, allowingdistribution of imagery products of up to25cmpanchromatic resolutionbyearly 2015.

Commercial satellites thus allow strategicmilitary users to focus their scarce militaryreconnaissance satellite on imageryintelligence (imint) and targeting, whilecommercial operators faced with huge

tasking constraints rely on dedicated spacesensor scheduling applications, such as theSatellite Toolkit from AGI, or theSTK/Scheduler and Collection Planning &AnalysisWorstation (CPAW) software fromOrbitlogic. The latter are under contractthroughMDAInformationSystemswith theUSArmysGeospatialCentre on theRemoteGround Terminal programme to supplymulti-satellite imagery collection planninglinkedwith commercial imageryproviders.

Multi-satellite operation results inenhanced collection synergies. Combinedwith the Spot constellation andnewGermanradar imaging satellites from InfoterraGMbH,AstriumGeoServicesoffer in2014anewWorld Digital ElevationModel (DEM)service at two-metre (relative) verticalaccuracy, challenging aerial photographyespecially for larger areas. This new breedallows rapid legacymapupdateaswell asnewproducts, tailored formilitaryuse. Inanycasehowever, the availability of accurate groundcontrol points is paramount to performortho-rectification of imagery, in order tomitigate distortions caused by the platformalong its orbit, sensor viewing angle, andenvironmental interference.Lastbutnot least,multi-band,multispectral sensorsoncurrentimaging satellites offer a highlydiscriminating power for terrain analysis(between foliage, crops, built-up areas, etc.),althoughat the expenseof resolution (trueorfalse colour images remain above one-metreresolution),andaccompaniedbyasteeprise in

An amazingly sharp image of Port-au-Prince, Haiti, collected by the relatively inexpensive Skysat-2 mini-satellite. Such breakthroughsurveillance and reconnaissance products, together with the recent ban on very high resolution imagery, are likely to transform geospatialinformation production in the coming years (Skybox Imaging).


complexity for image processing andexploitation.Artemis, anewsensorcarriedbytheTacSat-3 satellite, is the firsthyperspectralimaging sensor tailored to tacticalapplications fromspace. It isusedbyUSArmySpace&MissileCommandandArmyForcesStrategic Command in a joint exploitationteam, experimenting fast exploitation fortactical users, in a new trend bringing spacesurveillance closer to the soldier.

I DATA EXPLOITATION:POWERFUL SENSOR SUITESDigital-age sensors would be useless withouttheir accompanying software tools for sensorcalibration, correction, filtering andinterpretation, all leveraging an increasingamount of sensor metadata which augmentthe raw collection product. Geospatialmetadatadealwithdata identification,quality,organisation, spatial references, and otherattributes.Someare forhumaninterpretation,but others are input for automated imageinterpretation, photogrammetry, orgeospatial information software. Beyonddatadescription, theirmainuse is toperformadvanced processing on raw data andautomate workflows to produce map orterrainmodels out of huge amounts of data,while performing some level of qualitycontrol and standardisation. Althoughmostof these applications lie within commercialoff-the-shelf solutions, themost demandingones are either military off-the-shelf orbespoke software suite; often enough, they

combine all of these. The suite of servicesprovided by these products is referred to asTasking,Collection,Processing,ExploitationandDissemination, orTCPED.

Commercial products tend to blur thedistinctionbetweenphotogrammetry (post-sensor imagery computation) andgeospatialinformation systems (extractionandanalysisof terrain features in a database to managemap or elevation data). Even Adobe

Photoshopbrings imageprocessing closer tomapmaking,withmeasurement and filteringfunctions which can un-distort planarsurfaces, and tools to smoothen colour andtextures. Leica Geo Systems andIntergraphboth part of the HexagonGeosystems group since 2005providemulti-sensor integration and analysis suites.Theirhigh-level of automationandworkflowgeneration is regularly demonstratedduringEmpire Challenge exercises, bringingtogether British, Canadian, Australian andAmerican forces at theNavalWeaponCenterin China Lake, California. Military orprofessional collectionplatformsareusedas amulti-sensor input (e.g. Leica mediumformatdigital camera,Optech lidar,militaryGPS) for the production and disseminationof digital geospatial products, such as terrainmosaicsordigital terrainmodels.TheprovenErdas Imagine imagery analysis suite is usedto exploit multi-sensor feed, identify andcorrect data consistency, and producesmilitary-grade imagery for dissemination toalliedC2or ISR systems.

AhybridTCPEDsolutioncanbe found inwidespreadcommercial andmilitaryoff-the-shelf products, namely theBAeSystemsSocetSet digital photogrammetry and geospatialinformation system designed mostly fordefence applications. Its current 5.6 versionprovides point-matching algorithms formulti-sensor triangulation, turning digitalaerial photography (usually delivered in

stereo pairs) into ortho-images in raster(grid-based information) or vector format(where terrain features are translated intogeoreferenced points, lines and polygons).BAes new suite, SocetGXP, combines imageanalysis with geospatial analysis. GXPXPlorer enables analysts to access huge datasets locally or remotely, while streamliningand standardising workflow for geospatialinformation production. In a transitionmove from legacy bespoke capabilities tocommercial-based store-and-retrievecapabilities,NGAawarded a contract toBAeSystems to deploy GXP licences on anenterprise basis.

A somewhat more restricted, military-grade TCPED use can be found with theclearlymilitary-grade photogrammetry andimageanalysis suite fromOverwatchSystemsGeospatial Operations (part of Textrongroup). Remoteview is an advanced multi-imagery and geospatial analysis systemcentred on the exploitation of strategicintelligence collection assets: dual-use ormilitary satellites, as well as high-altitudereconnaissance platforms. In its currentversion, Remoteview 4 takes advantage ofhighgeodetic accuracyofnewdigital sensorsto generate orthorectified or mosaickedproducts from multiple map and imagerysources.Oneuseful function is its fast virtual3D rendering features, enabling analysts tocreate virtual fly-through of large gigabytedatasets.Dedicated extensions servehigher-endgeospatial intelligence requirements; theRV Screener module creates chips andmosaics from recce aircraft like the U-2R/Sanddrones like theGlobalHawkanddisplaysthem in a seamless waterfall format tofacilitate imagery analysis and changedetection; IGeoPos is a tactical imageryprecision positioning module, which grantsRemoteView users access to the highlyclassifiedUSDigitalPointPositionDatabase.This latter feature shouldbehighlyprizedbyanalysts, sincegeospatial intelligence is eithersharply defined or precisely georeferenced,but seldomboth.

MoretailoredmilitarysolutionscanhardlybefoundoutsideAmerica.Britainhasrecentlydeclared initial operational capability of partof its Picassoprogramme, an armygeospatialintelligence system delivered by LockheedMartin UK Information Systems. The FieldDeployable Geoint (FDG) programme hasbeen entrusted to the LockheedMartin UK-ledSocrates industrial teamtoaddressBritishJoint Force Intelligence Group requirementsthrough 11 containerised two-man tactical

exploitationworkingenvironment. ItsFrenchequivalent,MoyensGographiquesProjetables(MGP) delivered by Thales, has been used inAfghanistan and Mali to deliver geospatialinformationproducts to tacticalusers, thanksto advanced production and workflowautomation tools.

In Israel, higher-end systems mergegeomatics with imagery intelligence asexemplified by the IAI/Elta Systems EL/S-8994RTRicent (Real-TimeImageIntelligenceCentre). This is an applied multi-source,multi-sensor system for intelligence andtargeting. It incorporates an informationassurance component to check authenticityof contributingdata, andautomates searchofmatching imagery with better georeferencesto enhance locationof imageryof interest.

In France, AirbusDefence& Space offersthe Actint suite, an apparent re-branding ofpast references (Optimint Image IntelligenceSystem, itself derived from the EVI basicimage exploitation capability), combinesmulti-sat imagery acquisition with analysisand feature extraction.

Geo Data Design, a South Africancompany, proposes a lesser capable version(combinedwithErdas Imagineandothercotssuite for commercial imageryexploitation) tothe African region. The Thales GeoMakersolution is also a re-branding for militaryTCPED, probably closer to high-end US orIsraeli capabilities though; it combines high-grade geospatial exploitation references

(delivered to the FrenchMinistry ofDefencefor military mapmaking or cruise missilemissionplanning for example)with strategicand tri-service imint systems. In 2013,GeoMaker reachedout tonewhigh-precisionground mapping sensors, such as TopConhigh-density 3D laser mapper for mobilegroundapplications.

I INFORMATION PRODUCTION:THEWORLD OF GISGeospatial Information Systems integrate,exploit and analyse geospatial data,presenting them in layers in either raster (i.e.image-like) or vector (linear and polygonal)formats beforepublishinggeneric or tailored(thematic) geospatial informationproducts.As such, GIS used to stand in the middlebetween data collection and exploitationsystems; however, they tend tobroaden theirscope by incorporating advanced sensorprocessing features to exploit overheadimagery, lidar, video on the one hand, andprovide increasingly business-orientedproducts frommilitarymapmaking, on theother hand. To confuse matters even more,satellite operators develop their own GISservices. Furthermore, almost everymilitary-off-the-shelf or bespoke geospatialexploitation solution incorporates interfacesor modules of commercial GIS. If GIS areplentiful as mapmaking applications andgeospatial data presentation for variousindustries, the range offering trulymilitary

applications is quite narrow; militaryapplications encompass more rigorousgeoreferencing and quality control features,as well as tailored functionalities such asmilitary grid editing or tactical symbologymanagement.

Falcon View is one of the few earlyexamples of dedicatedmilitarymapmaking.Developed forPC/WindowsbyGeorgiaTechResearch Institute for free use by the USmilitary (essentially Air Force and SpecialForces formissionplanninguse) in themid-1990s, it hasmet a broad success within andbeyonddefenceuser communities.Anopen-sourceversionwas released in2009, althoughfor non-government users. With around40,000 users, Falcon View remains apreferred moving map application in mostAmerican military aircraft. The success ofthis raster-based mapmaking and displayapplication (currently in its fourth version)has ledmany subsequent andmoreadvancedsolutions toprovideFalconView-compatibleinterfaces in their product design.

I COMMERCIAL DEMANDTheGISmarket is increasingly drifting intocommercial applications though, and isdominated by few software vendors. Esri isleading, with about 35% of the militarymarketworldwide. In theUnitedStates, theirgain of the Commercial Joint Mapping ToolKIT(CJMTK)withNorthropGrummanasasystem integrator at the turn of the centuryhas positioned Esri as a key provider to thePentagon, which buys and distributes theEsri ArcGIS suite for integrationthroughout theUSmilitary.

Initiallyamapmakingtool forgeographers,ArcGIS, covering desktop, server or mobileversions,aswellassoftwaredevelopmentkits tobe integrated in business applications, hasevolved into a full geospatial productionsuite. Its latest 10.3 version has modules forabout everything in the geospatial trade,from imagery and lidar integration todedicated templates for C4I/BattleManagement applications, and is developingmission-tailoredgeo-analysis, fromcounter-piracy to submarine operations. A morerecent success was the recognition of theenterprise version of Arc GIS, when Natoselected Esri (with Siemens as an integrator)for their Nato Core GIS, placing thecommercial product as a central capability toserve Nato C2 as part of its overarching,service-oriented architecture.

Since then, however, Esri has been slowerinpenetratingmore tacticalapplications, suchas mobile battle management systems,artillery or dismounted soldier systems,despite a major partnership with Thales aspart of their Comm@nder integrated C4Icapability in the early 2010s. Today, Esritechnology pervades most imagery orcartography business application (includingcompetitors), although pure militarysolutions still rely on their validated andtraceable geospatial processing algorithms,leavingtoEsri the front-endprocessing,or themore standardised dissemination ofstandardisedgeospatial informationproducts.

Against this recognised success, rivalcommercial applications have found itdifficult to maintain their market share;Intergraph, Esris nemesis, has seen its

GeoMedia GIS market share erode despiteconsolidation with other core businessapplications (Leica Geosystems, ErdasImagine) within the Hexagon Group. Also,open-source applications, like OpenLayersor the FrenchGeoConcept (successful withGendarmerie, Army Aviation or TacticalAir Control Parties), are struggling tochallenge the strong Esri-Microsofttechnical andmarketing partnership,whichfederates a huge ecosystem of value-addingpartners around the two software editors(likeAGI or IHS/Janes).

Between full software suite andcommercialGIS,Geospatialdevelopmentkitsfill aniche for integrators todevelopgeospatialapplications in C4ISR programmes. One ofthe earliest vendors is the Belgian Luciad. ItsLightspeed geospatial component softwarereplaced Luciadmap in 2013, and is widelyused in sea, air, land command andintelligence systems. Luciad solutions offersimple development tools for integrators andsoftware developers to focus on opengeospatial data visualisation rather than thecomplex, expert digital mapping workshopsofferedbyGIS.Scandinaviancompaniesoffersimilar alternatives, like the Maria softwaredeveloped since the early 2000s by TeleplanGlobe inNorway; it has been adopted in C4Iapplications from joint command level to thedismountedsoldier. InSweden, theCarmentaEngine provides software components tobuild specificmilitaryapplications.

Against the rise ofGIS and their constantfunctional extension, is there still a need forbespoke defence geospatial applications? Itseems so, despite the growing presence of

Left, a Google image is used to place intelligence feed. Despite the nice look and feel, it is impossible to know the accuracy, origin and processingassumptions behind this information, which proved to be poorly geo-located (WF/Google). On the right is a sub-meter digital elevation model of thesame area built out of documented satellite imagery and the Thales GeoMaker geospatial production suite incorporating accurate sensors modelsover verified map data. The resulting product turns intelligence into actionable information for effect-based planning and precision targeting (Thales)



commercial components in military-gradeapplications. The reason lies with the need,for critical defence corebusiness (notably firesupport, intelligence or targeting), tomasterand validate key data transformationfunctions, in order to certify their reliabilityfor the most critical missions. The truth is,highly automatedandcool features likeon-the-fly mosaicking or instant buildingextraction out of heterogeneousmapdata incommercial GIS have their drawbacks; incutting corners by equalising or simplifyingloads of sensor-specific data, they blur theiraccuracy and traceability, which hardlycomplies with drastic quality controlprocedures of military applications. This iswhy higher-end military geospatialapplications still relyon theirownalgorithmsfrompost-sensorprocessing andanalysis,

I PRODUCT DISSEMINATION:STANDARDISED AND SERVICE-ORIENTEDWithout the structuring and integratingeffects of standards, the geospatial industrywouldstill bea stovepipedcollectionofexpertdataprocessingandanalysis,with segmentedexploitation and single-use authoring ofproprietary geospatial information. Beyondgrowing IT technology standards on whichgeospatial software solutions are surfing, therole of the Open Geospatial Consortium(OGC) is paramount. OGC, largelysponsored by the NGA, binds major GISsoftware players with system integrators andCOTS-MOTS solution providers; among

structuring standards, Web Map Services(WMS) or Geographic Markup Language(GML)standoutasenablersof self-describinganddiscovery standards.Particularly tailoredto enterprise applications, service-orientedarchitectures (where information discoverymechanismsenable informationpublishandsubscribe), and web services becomeincreasingly hardware-independent. Otherexamples are recognised data formats, suchasGeoTIFF,whichenables scalabilityof largeimagerydatawithoutcompression.Theroleofgeospatial or IT companies must also behighlighted, beyondIonicSoftware, leader inOGC-compliant solutions. Adobe, theinventor of the pdf light documentdissemination format, developed the geo pdftoallowgeoreferencingof informationwithindocuments. Esri, with its own shapefile dataformat, is alsodrivingdatadisseminationandinteroperability, with most GIS recognisingtheir competitors shapefiles as a quasi-standard. However, even Esris shapefile isbeing challenged by the OGCs latestGeopackage standard (GPKG), which packsraster, vector and symbology data in an objectdatabaseformat,toeaseinformationexchangesbetweenheterogeneous environments.

Theroleofdistributedarchitectures is alsokey to the generalisation of geospatialinformation products, where certifiedauthoring meets user-tailored visualisation.Forexample,3D-friendlyplug-inssupport fastbrowsing and exchange of high-resolution

geospatial products such as digital terrainmodels and fly-through. However, theirexploitation remains stuck at strategic andoperational (theatre) levels, accommodatingenterprises services onWeb2.0 technologies.Propagation of this level of informationremains highly dependent on constrainedtactical networks, as well as local processingcapacityofruggedembeddedhardware.This isprobably why the deployment of Nato coregeospatial services at theatre level (e.g. forISAF) is still pending, while paper maps(although made from digital geospatialinformation) still have a bright future to planandconduct fieldoperations.

The technologies behind geospatialacquisition, production and disseminationare increasingly integrated, resulting inhighlyautomatedgenerationofmulti-sensor,multi-layeredgeospatial informationproductsonaspeed and scale hitherto unimaginable.However, beyond the sexy look and feel ofGoogle-like geospatial displays, geospatialinformation production remains an experttrade, averticalbusinesshighlydependentonsensor data and metadata, along withcarefully followed workflow and qualitycontrol to build validated geospatial layers.The current status of geospatial informationshows growing availability of high-qualityproducts, thanks to eased disseminationstandards and powerful map displays. Thetrade behind the powerful software suitesavailable remainsdifficult tomanage though;

Propagation of this levelof information remainshighly dependent onconstrained tacticalnetworks, aswell as localprocessing capacity ofrugged embeddedhardware. This is probablywhy the deployment ofNato core geospatialservices at theatre level(e.g. for ISAF) is stillpending,while papermaps (althoughmadefromdigital geospatialinformation) still have abright future to plan andconduct field operations.

what isgained inuser-friendliness isoften lostin new specialised modules dealing withspecific sensors or tailored analysisalgorithms. The range of skills to master inorder to fully exploit the performanceenvelopeofhigh-gradegeospatial solutions isbroadening. Last but not least, the reliabilityof information assembled from multipleprovidersandheterogeneoussystemsremainsfragile, especially with cots solutions,restricting the integration of geospatialproducts across the sensor-commander-shooternetworkedcommunities.

I BIG GEOSPATIAL DATAThe proliferation of available sensors andtheir growing accuracy are creatingformidable store/retrieve challenges to bothoperators and users. As an example, theaforementioned Worldview-2 satellitedownloadsabout1000gigabytesofdatadaily;a wide-area surveillance drone produces aflow of 2750 terabytes of data daily. Thegeospatialworld is thus theprimarycandidatefor cloud-ready, big data solutions. Indexing

and tagging imagery, video and geospatialproducts are amust inorder toprovidebroadand timely access to geospatial information.Time, space and semantic analysis furthercomplicatematters foranalysts to leverage thesheer volume of sources available. Cloudtechnologies apply to geospatial big data toleveragedistant,heterogeneousdatabases intoa single repositoryof geospatial information.Tobridge the strategic and tactical levels, new

solutions are being applied to featureextraction, compression or bandwidthmanagement to provide content in aconnected and disconnected environment.Excelis Jagwire, for example, is a cloud-basedsolution which discovers and federates dataacross multiple platforms and organisesdistributedaccess toon-demandinformation,standardising data along the way incompliance with NGAs GeospatialIntelligence StandardsWorking Group. Forthe American Department of Defencessatellite imagery, Pixia software similarlyhandles very large datasets in single-composited layers.

Thenext challenge is thus for operationalusers to take full ownership of availablegeospatial products and augment, modify,fuse or tailor them for mission-specific use,while remaining able to trace andacknowledgemultiple data transformations.Thismission-driven integrationof geospatialinformation in C4ISR applications will beanalysed in the next episodes of ourgeospatial information series.

As seen in the earlier section of thisCompendium the digital battlespacehas been enabled by a revolution ingeospatial information technologies.Increased resolution sensors, automatedproduction tools, and standardiseddissemination formats are shaping the waymilitary operations areplannedand led.Theparticularly complex land environment,obstructed by weather, elevation, vegetationand human activity, is to benefit massivelyfrom this augmented digital description.However, this processdifferswidelybetweenthe higher-level generation of a gods eyeview, and the lower tactical echelon,constrained by limited connectivity and on-board informationprocessing.

I MAPOF THEWORLD RISINGAn attempt at building a cross-domain,foundation of geospatial intelligence(Geoint) from legacy and new geospatialinformation surfaced inmid-2014under theambitiousMapof theWorldproject launched

by the National Geospatial intelligenceAgency (NGA). This initiative aims atcreating a single common exchange service,acting as an anchor point to link natural andman-made features and explore semanticcontent attached to geospatial objects, fromphysical description to embeddedintelligence. Later in the year,NGAawardedBAe Systems Intelligence&Security sector a$335 million contract to develop, maintainand disseminate Geoint from Map of theworld;BAehadalreadycontractedwithNGAto explore activity-based intelligence tosupport dynamic analysis. Harris thenreceived a$770million, five-year contract tocreate geospatial data products, eliminatingredundant data to store the most currentrepresentation of each geospatial feature.NGA awarded two more millions to fivecompaniesmeeting innovation challenges to

exchange large data sets using datalinktechnology, mitigate conflicting data fromvarious sources, or develop a framework fordata ingestion, analysis and disseminationsupportinguser-generated content.

The Map of the World project is a clearbreakaway from static to dynamicinformation; in its final form in 2020, it willuse big data analytics to integrateinformation from imagery, digital maps,maritime and air safety data, aswell as socialmedia, to generate a highly documentedobject of interest and thereby answerparticular queries from non-specialists.Released in summer 2004 as an initialoperational capability, theprojectwas able tointegrate information from12heterogeneouslegacy sources under a unified format, toserve Geoint requirements of 17 agencies inAmerica.

Mapping the Land & Joint BattlespaceMaking use of digital geospatial information to prepare, infiltrate and dominatethe land battlespace is still the privilege of higher echelons of command, able to accessand exploit multiple sources of intelligence. But the rise of on-board or personalnetworked terminals is also offering rich functionalities to insert land forces in complexhuman and natural terrain.

Map of the World reflect NGAs ambition to transform geospatial information intodynamic, on-demand integration of multiple data sets to produce geospatial intelligenceattached to any object of interest in the battlespace (NGA).

Access is facilitated throughthe Globe, a web portal where accreditedanalysts can search an object of interest inspace and time, generating layers ofgeospatial informationarounda target site ora mere individual. Published in highlystandardised formats, this information ismeant to be portable, with connected anddisconnectedusersable tobrowsepetabytesofcontent and update it on an on-demand,user-defined basis. A follow-on to theenterprise geospatial informationprojects ofthe early 2000s,Mapof theWorld is themostambitious geospatial initiative to date, andwill inspire similar initiatives in othernations, already committed to unifyenvironmental information services.

The US Army embarked in a similarendeavour with the Armys GeospatialCenters Common Map Background. Thisprogramme is bridging NGA and Armycontent, to ease access to a broad range ofgeospatial information products (fromdigital elevationmodels to geopdf files) fromusers in the field. Access will be grantedthrough a web portal, with datasets madeavailable in standardised format, anddissemination allowed through an FTP site,DVD, or external disk drive. Afghanistanwas chosen as the first implementation,giving way to standardised data sets of thecountries geospatial features.

I THE RECOGNISEDENVIRONMENTAL PICTUREThenotionofsharedsituationalawarenesscanbesimplydefined toanswer thecritical whoswhere question inmilitary operations. In itsultimate form, it is delivered as a CommonOperational Picture (COP); but this multi-layered, geo-located view has hardly becomeareality inhigherheadquarters, challengedbya refined description of the operationalenvironment, defined as the RecognisedEnvironmental Picture. The REP is anambitious endeavour to describe in digitalformats all aspects of the operationalenvironment: geography, hydrography,oceanography, and meteorology. As a by-product of the intelligence preparation of thebattlespace, it is thus capable of serving allmilitary users (army, navy, air and specialoperations forces), and can be seen as thefoundation of the COP. Building theRecognisedEnvironmentalPicture,however,entails leveraging the very best of terrain,water and weather generation tools; and thisfinding is even more acute in the landenvironment where natural and humanfeatures converge to load topography withsurface details. REP components have beenfoundforsometime,althoughinaproprietaryformat, held by a loose community oftopography, oceanography andmeteorologyspecialists. Today, leveraging new andincreasinglystandardisedgeospatialproducts,REP is athand inahandfulof countries, from

where it will logically spread tomost defencestaffs.Duetothehighvolumeofdata,modernIT is seen as a powerful enabler to bringtogether environmental data: enterpriseservices, subscribing to distant networkedcommunities, service-oriented architecturesandWeb2.0 technologiesall combine toallowaccess to user-defined information servicesandbuildingof adhoc informationproducts.This will give rise to new specialties innetwork-centric operations, such as a REPmanager, tasked with pulling geospatialinformation to serve dedicated demand forsuch operational services asweather overlaysfor drone operators, helicopter landing zonesfor army aviation units, or route computingfor logisticplanners.

In America, Britain, France and withinNato, Recognised Environmental Picture isslowly being experimented to fuel planningor commandand control of network-centricoperations.

I HUMAN TERRAINBeyondenvironmentaldatadominatedbyphysical terrain features, the currentoperational environment has broughtabout the need for accurate informationon human activity in places often alien towestern cultures: Afghanistan, Iraq,Malior Somalia. In these highly traditionalsocieties, the notion of human terrainbrings value todeployed forces in termsofsettlement, allegiances, or centres of localpower, all valuablenotions for intelligencegathering, psychological operations, or

urban control.Although human terrainis usually associated with the intelligencepreparation of the battlespace, it isvaluable topolice andmilitary operationsas well, as long as it enables forces in thefield to better insert their actions in acomplex social andcultural fabric.TheUSArmy embarked in the Human TerrainSystem programme in 2007, initiated by acontract toBAeSystemstorecruitandtrainsocial science specialists to serve as fieldscientists and advisors (human terrainteams) in Iraq and Afghanistan. Closer toa psychological operations project thangeospatial intelligence, theHumanTerrainSystemhasproducedanthropologicaldatanot easily integrated in a common GIS.However, it can leverage non-traditionaluse of geospatial exploitation, powered bynewfunctionalities suchaspatternanalysisor activity-based intelligence, cross-database exploitation, and advanced data

An ongoing effort,the CMAP geodatabase includes culturalcomponents over 120 countries and regionswith ethnic, tribal, religious or languageaffiliation, and contains roughly 60,000features. Although in its early phase, humanterrain analysis in counter-insurgencyoperations remains shrouded in controversyabout the use of social sciences to winninghearts andminds.

I ON-BOARD GEOSPATIALBATTLE MANAGEMENTThe powerful, layer-based geospatialinformation management has found agrowing demand beyond higher-levelcommandposts, for intelligencepreparationofthe battlespace or mission planning. Thetactical exploitation of this powerfulknowledge is far less advanced, though, dueto cultural and technological obstacles.

On cultural grounds, one must bear inmind that the special skills required forgeospatialdataexploitationare seldomfoundin deployed command staffs below brigadelevel,wheremissionexecution leaves fewseatsfor intelligence or geospatial analysts.Battlespacedigitisation thuscomesata slowerpace for the mobile warfighter, despite histhorough skills for traditional map readingand field navigation. Northrop Grummanmission systemsbecame famous for theiruseof blue force tracking (now a patented NGterm)whensevereweatherconditionsduringthe 2003 invasion in Iraq disrupted visibility(as well as voice communications) and

armoured vehicle crews had to resort toswitching on their screensruggedizedcomputers attached to their combat netradios. To their surprise, they displayedtactical symbols on a pan-and-zoom map,showing type and position of friendly units.Since themid-2000s this capability has beenslowly disseminated throughout land forcesasBattleManagementSystems (BMS).

ABattleManagement Systemshosts, on acomputer, several operationally usefulfeatures: message handling, tactical editor,

map management. It usually is coupled to adata communications interface for thecombat net radio. This allows tacticalcommanders, typically from battalioncommand posts to individual vehicles, toprepare, exchangeanddisplay tactical orders,shifting from the legacy structured textmessages (inherited fromstandardisedvoiceorders) to map-based graphical situations.From the lengthy, text-based situationalawareness of the early 2000s,BMSusershaveshifted to largely automateddisseminationofalerts andoperational or fragmentaryorders,based on geo-located, standardised tacticalsymbologyknown in theUSmilitary asMIL-STD2525or inNatoasAPP-6.Commanderscan thus create, exchange andupdate tacticallayers of unit, manoeuvre or volume typesdescribing their position, course of action,and boundaries. More mature versions cantap into the limited array of army sensors,fromEO/IRcameras tomini-drones.

Technically, this process inherited fromthepapermapsand tactical drills generalisedduringWWII, stumbles against a number oflimitations. The most obvious one is thelimitedbandwidthavailable to sharedataovertactical radios;most legacycombatnet radiosallow either voice or data exchanges, and themost recent ones (such as the Thales PR4G

F@stnet or the Harris PRC-117) allow a fewtens of kilobytes of voice and data to transitbetween a limited number of mobile userssharing the same VHF network. This tailorstactical exchanges to friendly force tracking,oralert dissemination, while dissemination ofcommanders intent can take up to a fewminutes todisplay as agraphicalmapoverlayin each vehicle. Another constraint is thelimited computational power available onboard.Ruggedpersonal computers ormulti-function tactical displays are morecomfortable with static, low-resolutionimagery (satellite pictures or raster maps)thanheavy sets of vector data to dynamicallypan, zoom, or refresh tomatch vehicle speedonamap.Lastbutnot least,mobile, on-boardC4IrelyonITarchitecturewhichmustbeableto operate as a self-contained, oftendisconnected heavy client, far from rich(oftenWeb-based) client-serverarchitecturesavailable inheadquarters.

This set of constraints explain why mosttactical geospatial exploitation relies mostlyon dots and arrows on a map, whereasadvanced C4I functionalities remain absentfrom lower tactical echelons. The fastevolution of CPU and GPU, even on tacticalcomputers, is easingthesebottlenecks though,and the latest BMSs now embark powerfulmapmanagement functionalities, featuringcomputation of line-of-sight, waypoints,weapon and sensor footprints; the resultingshared situational awareness is transformingarmy manoeuvre in the digital age. ThalesCommunications, concentratingmost of theEuropean integrators C4ISR expertise (fromtactical radio to command & controlinformation systems and cyber security), hasbeenpromptto leveragecommercialandNatostate of the art capabilities. Its Comm@nder

family of integrated C4I systems has beenfeaturing exploitation of rich geospatialinformationontactical computers since2007.In 2010,Comm@nderBattlegroupbrought anew dimension to battle management, byintegrating information from vehicleelectronics (vetronics) and specific missionsystems according to vehicle type(reconnaissance, infantry combat, direct orindirect fire support, etc.) into the BMS. Thisallows integrating tactical data and videoinformation with geospatial analysis in threedimensions, displaying accurate navigation,vehicle status, sensor and weapon footprint

down to each combat vehicle. This solutionhas been selected by Malaysia for their newgeneration of 8x8 combat vehicles locallyproducedbyDefTechintwelvevariants,able tooperate innetworkedbattlegroups.

A steady improvement curve is alsoreflectedby theNorthropGrummanMissionSystems series of FBCB2 battle managementsystems. Fielded in the early 2000s as a BlueForce Tracker, the Joint Capability Releaseversion of FBCB2 common to US Army andUSMarine Corps can handle imagery, videoandcartographytodisplaygraphical situationsand exchange tight data sets in VariableMassage Format, the datalink-like standardcompatiblewithAmericancombatnet radios.Although less integrated into vehiclesubsystems than the Thales Comm@nder(resting on a vehicle electronics core), theFBCB2 rests on a proven, massive installedbase; as akey informationsuperiority enablerthough, it is notwidely exported (Australia isknown to be the only ForeignMilitary Salesbeneficiary), even if the Samsung-ThalesKBMS poised to enter service in Korea looksvery similar incapability.

Elbit follows a similar path, with tacticalterminals displaying simple map-basedtactical situations with little vehiclesubsystem information (outside gun layingand target acquisition formain battle tanks)in theirWINBMS family.


This multi-layered map of Afghanistan combines air coordination information, historisedimprovised explosive device information, and the days significant enemy activities.Leveraging core geospatial services and user-generated content, it illustrates state-of-the-artgeospatial intelligence exploitation at joint level (NATO).

A BMS embedded in a reconnaissance vehicle displays both imagery and geospatial data,with decision aids to identify an observed vehicle and turn an observation into a georeferencedtactical object. This local situational awareness is highly interoperable and saves thebandwidth of constrained tactical radios (Thales).

The French SIT (Systme dInformationTerminal) installed by Nexter in combatplatforms, or the Sagem SITel fitted inarmoured personnel carriers and lightvehicles, are contemporary solutions withsimilar functionalities, using mostly rastermap as background. The ambitious Frenchnetworked integrated battlegroupprogramme, Scorpion, has shifted therequirement for battle management to ahighergroundwith theSystmedInformationde Combat Scorpion. Breaking away from theterminal level of command and controlmessagesandsituationalawareness, theSICSisdesigned as an army equivalent to a navalcombat management system; it featuresadvancedtargetallocationandfiringsolutionscomputationfunctionalities, althoughits levelof geospatial information managementremains inherited from the legacy of mapdisplays rather than leveraging truegeospatialinformation power. Scheduled to equip thenew generation of digitised combat vehiclesaround 2016, the SICS is being developed byBull, a French software house. It will have tocloselymatch thenewgenerationof software-definedradiosdevelopedbyThalesunder themulti-billion euro contact programmerunning inparallel toScorpion.

At the other end of the spectrum liecommercial-based software productsdesigned to leverage the best of currententerprise GIS technologies. The SystematicSitAware family is proposed by the Danishsoftwarehouse in aBMSconfiguration; it hasabandonedEsrisArcGIS to leverageLuciadsLightspeedembeddedgeospatial componentsoveraMicrosoft suite inaruggedcommerciallaptop. Although handy for deployed tactical

I GEOSPATIALLY-ENABLED SOLDIERSoldiermodernisationprogrammesaugmenthuman eyes with day and night surveillanceand target acquisition optronics. Localsituational awareness in soldier C4I calls forbasic but critical information: where are myvehicle, team leader and fellow riflemen?Putting this information on a map takes alight, ruggedized form of personal digitalassistant inmanySMPs,with thedrawbackofhaving to look down at a small screen in afirefight. This is probably why soldier C4Icomes either as adismountedkindofBMSor

an enriched kind of digital compass. It cancombine both, like in the NorwegianNormansprogrammeor theBritish Fist bothled by Thales, with the former leveraging theTeleplanGlobeMariageospatialdevelopmentkit. It can also leavemap-based situations forthe platoon leader, like in the early Sagem-deliveredSitcomdeequippingtheFlinsoldiersuite inFrance.Butanewapproach to tacticalterrainreadingcanalsocomefrominnovativestart-ups like the GroundGuidance softwarefrom Primordial, a small Minnesota-basedbusiness created in 2002by anMITgraduate.GroundGuidanceuses standardmap-data tocompute variousoperational features: fastestroute, but also least exposed or least slopedfor vehicles or foot soldiers in open or urbanterrain; intervisibility, with an opticalvegetation penetration model; alternate orrandomised routing inurban terrain.Able toanalyse terrain fromthepixels of a rastermapto digital elevation models and vector data,Ground Guidance also comes with its ownGPU-based route computing algorithm,which is twenty-two times faster than itsCPUequivalent. Used for both mission planningor mission execution by small Army unitsand special forces, Ground Guidancesoftware development kit is deployed inFalconvieworXPlan, andhasbeen includedby Lockheed Martin in the eyepiece of itsGroundSoldierEnsemble.

Such innovative geospatial informationsolutions designed to leave headquarters toserve tacticalusers in the fieldare still few,butthey are called to spread, offering mission-tailored functionalities which can leveragegeospatial information at a similar level togeospatial intelligence systems deployed inhighercommandposts.

The Ground Guidance software wasincluded in the early phases of the Land

Warrior programme to provide an intuitiveroute planning tool displaying terrain costs

in terms of concealment, distances, andphysical costs (Primordial software).

Were all sons of Flight Simulator.For a long time, we used toconsider terrain information as aconvenient green and brown carpet overwhichwecould, using a fewvisual referencesto plot course and keep track of position andtargets. This notion is being challenged bymultiple new trends: increased density of coalition air-to-groundmissions in permissive airspace;

increased need for accurate effects of airmissions, in all weather, day and night,with a growing air-land integration andbattlemanagement; increased congestion of airspace inmilitary operations, withmultiple drones,helicopters, aircraft sharing the thirddimensionwith occasional ballisticpaths of rising or falling ordnance andlast but not least,

manynations are facedwith growingcivil-military integration requirements tomanage their airspace at all altitudes.

Digital geospatial information thusenables air control to leverage the full set ofbattlespace dimensions: sea, land, air,space, information, and more importantlyelectromagnetic spectrum and positioning,navigation and timingdata.

Air is a key dimension for battlespacemanagement; it provides freedom of actionand higher observation positions, free fromthe frictionof terrainobstacles (althoughstillimpactedbyweather). Its commandalsocallsfor dynamic coordination between terrainfeatures and navigation procedures. This iswhyaeronautical chartshave little incommonwith topographic maps. They do leverageterrain information though, augmenting itwith dedicated information to segment,navigate, and mitigate airspace use. Visualflight route air maps thus look liketopographicmaps at first glance, but they areladen with flight-related information aboutinvisiblevolumes, corridors, visual landmarksand obstacles, and numbered informationabout runwayapproachor radio frequencies.For instrument flight rules, topographicinformation disappears altogether, to centreon procedures, airways and navigationinformation. Aeronautical charts markinvisiblewalls in the sky, anddisplay codes toenter or avoid them.Military air dominancefurther adds to this complexity, combiningprocedural control to navigate airspace, aswell as positive control from sensors (radars,IFF) and weapon systems to identify, track,authoriseordenytheuseofparticularareas. In

Mapping Thin AirAirspace is probably themost demanding dimension foraccurate ground and 3D positioning information. Nowhereelse is extensive environmental descriptionmore indemand from fast movers and ground control alike, toprovide air safety, plan navigation routes and approach indense environments, or orchestrate complex air operationsatmultiple altitudes betweenmanned and unmanned airvehicles, missiles and artillery. Today, as airspacecoordination increasingly relies onmerged topographicand aeronautical data, the need for digitised, integratedgeospatial information rises towards Earth orbit too.

A raster aeronautical chart is augmented with a drone flight path against adverse radardetection patterns and missile ranges over the Persian Gulf, provided by AGIs System Tool Kit.This kind of simulated or live data is extensively used in planning and control of droneoperations worldwide (AGI).

A typical VFR air navigation chart displaysprocedural information over terraindescription. This kind of support, in paper ordigital form, provides basic air navigationtools worldwide (Jeppesen).

representing suchmulti-layeredphysical andsemantic information, digitisation andinformation systemscome inhandy,whereasadvanced information visualisation,supportedby3Ddisplay technologies, freeairnavigation from the flat representations ofpapermaps.By integrating static information(terrain features, airspace volumes, radiofrequencies) with dynamic information(altitude, speed, and time computations forfast-moving air vehicles), new geospatialinformation products have emerged toenable aircraft pilots to focus on theirmission, while planners and controllers cande-conflict and synchronise air operationsat combined, joint and allied levels.

Typical aeronautical charting products,such as 1:250 000 JointOperationsGraphicsor 1:500 000 Tactical Pilotage Charts,distributed by East View Geospatial (EVG),still provide the bases of air navigation; butthey are used as a basic information layer,over which to integrate automation andcomputation features to maximise use ofairspace; this is why raster air maps, with orwithout vector or elevation data, are thebread and butter of drone ground controlstations. For on-board systems though,all electronic navigation aids require

certification from both civil and militaryauthorities to be granted access to thecockpit. In the US for example, the NationalGeospatial intelligenceAgencys aeronauticaldivision is responsible for dissemination ofaeronautical charts, themselves compliantwith theFederalAviationAdministration. Inthe late-2000s, NGA embarked in anenterprise-scale roadmap to industrialisedigitised aeronautical map production andupdate, to ease integration into electronicnavigation systems. A new AeronauticalInformation eXchange Model (AIXM) wasdeveloped to share standardised routeplanning, in-flightnavigationor take-off andlanding information update betweenincreasingly connecteddevices, on-boardoron the ground. On the vendor side, leadingaeronautical chart providers have started toteamwithgeospatial informationcompaniesto enhance accuracy, information content,and interoperability of their products; forexample, the same East View Geospatialteamed in 2012 with the younger PlanetObserver, todistribute global andup-to-dateterrain data. Combined with rich aviation-related metadata maintained in English,Arabic, Chinese and Russian, EVG is readytomove to full electronic charting.

I ELECTRONIC FLIGHT BAGSThe electronic charting revolution started inthe late 1970s in the mission-criticalaeronautical sector, to equip fourthgeneration fighter-bombers with movingmaps. A sound reference is the family ofHarris Flitescene digital maps, supportingvector (navaids, airways, airports, etc),vertical obstruction points, and tacticalsymbology. Flitescene software still equipsmost of the US special operations aircraft.This level of digital information, whichreplaces the pilots kneepad map display, isalready valuable to plan air missions andsupport in-flight navigation. In turn,standardisation and dissemination ofinformation technologies impact defenceapplications, and civil aviation electronic airnavigation products now changes militaryflight operations. Jeppesen, a Boeingcompany famous for its aeronautical mapproducts, provides integratedgroundandairinformation on mobile devices, pioneeringthe concept of electronic flight bags (EFB).EFBs not only reduce paper volume taken byflight crews, they also act as computingdevices, able to match aircraft performanceandnavigationdatawith terrain, airspaceandairportdatabases tomaximise anairmission.iPad-borne EFBs were thus adopted in 2012by both US Special Operations Commandand Air Mobility Command, sometimes

I INTEGRATED FLIGHTMANAGEMENT SYSTEMSIn the mission-critical domain, flightmanagement systems (FMS) have replacednavigators and flight engineers (and in somecases navigation computers) as the ultimateon-board aeronautical informationapplication. FMS manage flight plan frommultiple databases, updated on a monthlybasis, to determine aircraft position andcompute the course to follow by the pilot or

the autopilot. Military aircraft can augmentnavigational sensors (radio beacons, aircontrol radars, or differential GPS) withdedicated on-board sensors (inertialnavigation systems, terrain-following radar)to provide very accurate positionalinformation. The most demanding airmissions, such as close air support or specialoperations (inserting commandosatnightorinbadweather in radio silenceandsupportedby passive sensors only), require highintegration and automation betweenmultiple information databases to providevery strict platformcontrol. For example, theGarmin GTN 750/650 helicopter-specificdatabase manages 30 000 low altitude

obstacles, navigation information, combinedwith heliports, helicopter landing zone, andhigh-resolution terrain mapping. Takingintegration furtherwith cockpit avionics andflight controls, Lockheed Martin Helisurefamily of integrated flight decks for criticalmission helicopters combine FMS with asynthetic vision system, helicopter terrainawareness and multiple threat warningsystems. A similar top-of-the range solutionintegrating aeronautical charts, terrain andobstacle information, is proposed by Thalesfor its Topdeck military helicopter avionicssuite, adopted by the RAF for its upgradedCH-47ChinookMk4 after an initial successon civilian Sikorsky S-70.

I AIR C2 AND BATTLE MANAGEMENTGeospatial information integration in tacticalmission systemsarekey enablers ofnetwork-centric operations. Managing the air battlecalls for simultaneous sharing of terrain,navigation, and real-time trackinginformation about friends, neutrals andhostiles. For on-board missions, provensystems such as the Rockwell Collins JointMoving Map Tactical Information DisplaySystem (JMMTIDS) combine networkingand messaging information from tacticaldatalinks with navigation and terraininformation (from imagery, digital terrainmodels, and aeronautical charts). Theresulting local situational awareness enablesfighter crews to focus on delivering their

aircraft and its payload over recognisedtargets, maintaining situational awarenesswhile navigating around obstacles, threatsandcollision risks. Sharing tactical situationsover tactical networks paves the way to air-land-integration between fighter aircraft,tactical air control parties on theground, andsupported armyor special forces units.

For ground-based air defence, latest-generationairC2smergemultiple sensordata(radar and military navigation aids) withaccurate terrain mapping to generate andmanage multiple airspace volumes. Theresulting positive control, arrayed on tacticalcommunications networks between radars,missile batteries, and command centres,provides safe orchestration of complex airoperations while accommodating civilaviation requirements. The Nato AirCommand&ControlSystem(ACCS)unifiedairC2,deliveredbyThalesRaytheonSystems,enjoys such capabilities. It can provideallocation and monitoring of extendedairspace while performing planning andcoordination of unmanned aircraft vehiclesand helicopters (in so-called standard-usearmy aircraft flight routes) with multipleaircraft flight profiles (combat, combatsupport, mobility or special missions) atcoalition level. Its interoperability

requirements enable the ACCS to exchangeinformation with civil aviation authorities,army aviation or field artillery unitsrequesting ballistic trajectory corridors fortheir firemissions.A fewcountriesboast suchanadvancedcapability as theNatoACCS; the

I NAVIGATINGORBITAL SPACEThe increasing integration of space assets incurrentoperationshasdrawnattentionontheneed tobettermanageEarthorbit, inorder tomaximise access to it, ensure availability ofspaceassets, andtheir survivabilityagainst themany natural or man-made threats to spacevehicles.Thegrowingcongestionof lowEarthorbit or geostationary positions by active orinactive satellites, and a rising number ofdebris posing risks to active satellites, adds tointentional threats to unattended spaceplatforms. This congested and contestedenvironment has given rise to spacesituational awareness as a new, vitalcomponent to information superiority innetwork-centric operations. One might betempted to wonder about geospatialinformation in space though; groundreferences lie far below, andorbit is free fromairspacerestrictionsonsafetyandsovereignty.However, space is not without trajectories,flight paths and obstacles, even if all abide bythe predictable laws of space mechanics. Aspaceobject canachievea stabilised trajectoryin orbit; but it is always subject to slightoscillations, and its orbital parameters canbe

altered to avoid slow erosion of residualatmosphere, or collision risks with spacedebris. Also, space weather, from cosmicradiation or solar activity (solar winds oreruptions which trigger sudden chargedparticle flows) can have a disrupting or evendamaging impactonspace systems, aswell asgroundcommunications infrastructure.Lastbutnot least, a satellite ground footprintmustbe assessed with accuracy, to compute itssensor swathandpoint imagersaccurately forobservationsatellites (whichnormallyoverflya given target site once a day and for a fewminutes), ground spots for communicationssatellites, or their line-of-sight with groundcontrol stations for sending commands ordownloading information in a narrow timeandspacewindow.

Space control is not only earmarked forcommercial or government satelliteoperatorsworriedwithquality of service; it isalso a privilege of a few space-rich militarypowers, whose space assets are key toinformation superiority: communicationssatellites ensure connectivity on a globalscale, free fromgroundnetworks; navigationsatellite maintain positioning accuracy andcommon time references, grantingsubscribers with sub-metric navigation andtargeting; observation satellites provide

regular access to areas of interest, free frominterference from ground or air, to map,discover or assess damage.All these strategicassets must be controlled though, not onlyto fulfil their individualmission (sensor andplatform alignment, tracking of groundantennae) surviving the hostile orbitalenvironment, but to synchronise flightoperations as constellations (e.g. optical andradar surveillance).

This is why military space operationcentres in a handful of countries (US,Russia,France,China and Israelmainly) share amixof commercial and bespoke tools to providesituational awareness and ensure accuratecontrol of their space assets. One such tool isthe Satellite Tool Kit (STK) from AGI,augmentedby a specialised space situationalawareness software suite. Connected to liveor simulated sensor information (groundradars or optical telescopes) andusing spacetracking algorithms, the STK can providereal-time tracking of space objects, analyseinteraction between payload and terrain,alert on collision risks, and mitigateelectromagnetic interferenceordegradationofsignals. US Space Command in ColoradoSprings is a long-timeSTKuser;memorandaof understanding between Joint SpaceOperations Command in Vandenberg AFB

and allied countries (France, Israel orABCAallies) often rest on exchange of informationmanaged by or compatible with the STK.The growing need to maintain spacesituational awareness, notably a catalogue ofsome 23,000 tracked objects of more than10cm in orbit, or early detection of solaractivity, has fuelled a service-based initiativefrom AGI and the private Space DataAssociation to provide commercial servicesto proven or emerging space powers. Therecent Commercial Space OperationsCentre initiative (ComSpOC) is thuschallenging legacy space surveillancesystems that can be tempted to augmenttheir non-critical space tracking activity bythe AGI-provided Spacebook catalogue oforbital objects, or leverage sensors on aglobal scale. The most ambitious spacesurveillance programme to establish andmaintain a detailed space object catalogue istheSpaceFenceprogramme, grantedunder a$914 million contract to Lockheed Martinagainst Raytheon; from 2018 on, SpaceFence will merge data from new S-bandground radars, large telescopes and space-based surveillance satellites, to feed a spacesituational awareness command centre.

Since space power is increasingly linkedto sovereignty though, progressmay be slowbefore space surveillance is left to non-national, private entities. A more pragmaticapproach is a burden sharing betweeninternational bodies (e.g. the EuropeanSpace Agency), national space agencies,

commercial providers or partof the scientific community, toprovide common services totrack hazardous objects inorbit,warnon re-entryof largeobjects, or anticipate andmitigate space weather. Moremission-critical tasks, such asthe safe operation of nationalsatellites, or the tracking ofadverse space capabilities (in-orbit or through their groundfootprint) can thus be left tomilitary forces. France hasrecently embarked on apermanent space surveillancecapability in a newly-openedfacility near Lyons; manned24/7 by air force crews, itwill deploy the SystmedInformation Spatiale, a spacesituational awareness C2granted to a consortium ledbyThalesAlenia Space end-2014;the SISwill leverage expert tracking of spaceweather, as well as the modernised Gravesbistatic radar mapping objects in low orbit,designating some to dedicated orbitographyradars oroptical telescopes. In any case, suchcapabilities are drawing interest from agrowing number of countries outside spacepowers, either because they have recentlyacquired valuable space assets, or becausethey worry about the use adverse countriescoulddoof their own.

Aerospace geospatial informationrequirements thus differ from classicalground mapping, integrating much moredynamic (semantic or spectrum-related)knowledge,while powerful decision supportand asset optimisation potential rests onsuccessful and accurate integration ofaerospace and terrain information withweather (space or atmospheric) data, sharedbetween fast movers and operational ortactical commandcentres.The trendhas justbegun to exploit informationof aeronauticalinterest in all dimensions of the battlespace,and serve communities of interestwithhigh-resolution, accurately located andstandardised geospatial information. Fewcompanies combine the know-how of high-

grade geospatial information production,integration into standardised, enterprise-based architectures, and dissemination ofhigh-value services to operational users. Butthe growing role of geospatial informationsystems, and the increasingly matureinteroperability standards in both thecommercial and military domains, bears abright future inexploiting immaterial fieldsofthe battlespace to augment ground andatmospheric physical information.

This is probablywhy the leading chartingcompaniesdescribed in theair andspacepart, such as Jeppesen or Navionics,provide also high-grade marine charts forcommercial and military users. Nauticalcharts, however, comply with specificrequirements to describe coastlines andmaritime areas, as well as ocean depths andmain seabed features, natural or man-madenavigational aids, marine currents and tidal

activity. Such knowledge rests on nationalhydrographic offices coordinated by theInternational Hydrographic Organisation(IHO). Within historical naval powers, theNational Oceanographic and AtmosphericAgency in America, the old British

OceanographicOffice, and theFrenchServiceHydrographique et Ocanographique de laMarine thus produce official marine charts(e.g. the famousBritishAdmiraltycharts) thatupdatedona regularbasis.

I ADVANCED SENSORS, BETTER DATA,NEW STANDARDSThe maritime domain forms a complexinteraction between the sea floor, watercolumn, the sea surface, air column, anddynamic information about navigation,weather or obstacles. To comply with thesafety and security missions of most navies,this specific battlespace is surveyedby awidevariety of subsurface, surface, air andspace sensors, mostly of dual-use betweengovernmentsandthemilitary.TheNasa Jasonsatellite provides accurate measurement ofwaveheight and sea levelsworldwide; its datacan be consumed in near real-time to plannaval escorts to pirate-threatened maritimetraffic in the Horn of Africa. Airborneimagingor ranging sensors like lidarsprovideaccurate coastal contours, or gatherbathymetric information in shallow waters(using for example a blue-green laser topenetrate water and infra-red laser tomeasure surfaceheight).

Mapping the Seven SeasMarine charting started in the ancient times, and thepower of a navy has since beenmeasured by the qualityof its charts. On a predominantly oceanicworld, mappingthemaritime environment amounts to summing up all theknow-howand constraints described in the previouschapters: the complexity of coastal, surface andsubsurface features is augmented by specific humanoccupation of the littoral, the changing and dynamicnature of the seas, aswell as their peculiarweatherpatterns; on top of this, navigational and traffic controlinformation is adding up an extra, critical dimension.Fortunately, digital-age information products translate thiscomplexity into critical decision-making tools.

Multi-sensor input has brought positive and negative elevation to marine charting,enhancing visualisation through electronic navigation charts, illustrating the multi-dimensionalaspect of the Maritime domain (Jeppesen).


Ship-borne or submarine sonars, fromsingle beam to multi-beam echo sounderscombining sensor swathe with attitudesensors,gyrocompass,andinertialnavigation,deliverbathymetric information tomapdeepseafloor features.Other sensors surveyoceantemperature, salinity, and tidal flows. Theresulting amount of data can be extremelycomplex to integrateonasingle, standardisedsupport such as the old paper map; the stillexperimental or academic use of the mostadvanced hydrographic or bathymetricsensors also adds to the data exploitationchallenge. This is why marine charting hasfound the useful help of digital technologies,giving way to electronic navigational charts(ENC);departingfromscannedmarinechartsto provide dynamic information, ENCstranslatevast amountof information intosetsofstandardiseddata,producingintelligentandinteractive maps able to manage and displaymulti-layered information, often combiningrasterandvectordata (see first section).

The wide array of data collection sensorsand their scientific orientation have sloweddown standardisation, still lagging behindcomparable land and airmapping products.Commercial geospatial information systemshave only recently started to cope withmaritime geospatial information, both fortheproductionandexploitationof intelligentdigital maps. The most internationallyrecognised format in marine electroniccharting is the IHO-approved S-57, alongwith its S-63 encrypted variant. Companieslike Jeppesen provide conversion tools tobring legacy and exotic data onto S-57maps.However, this maritime standard is slowlybeing accepted in commercial GIS. Luciadwas early to provide S-57 visualisation tools,thanks to its early involvement with Thalesat the turn of the century to deliver ship-borne and shore-based commandinformation systems, notably for the new-generation SIC 21 maritime C4I system-of-systems for the French fleet command. Esrifollowed suit, developing its ArcGIS formaritime operations alongside its version10.1 in the early 2010s. This suite offunctionalities leverages Esris priorinvolvement inenterpriseGIS forNOAAandother maritime users in America. Itcomplements Esris ocean basemap servicesreleased in 2011 on ArcGISonline, filling agap and demonstrating how poorly theworlds ocean are mapped today. Oceanbasemap is planned to move in scale fromtodays 1/500 000 to 1/72 000 aroundAmerican coasts.

As S-57 was developed when computingpowerwas farweaker, electronic charts soonreached their limits in incorporatingmarinedata. So the rich metadata associated withmaritime information systems have led todevelop S-100 and S-101 formats, designedto replace S-57 for new-generation ENCs inthe mid-2010s. These new, more open IHOstandards augment pure geospatialinformation with marine-relevant dynamicinformation. The S-100 hydrographicgeospatial standard for marine data andinformation supports multiple data sets:bathymetry, 3D and temporal information,or trackingsensordata, suchas radar tracksorAIS (Automatic Identification System).Beyond at-sea navigation, the new formatenables route planning, coastal and harbournavigation, and takes into account dynamictidal models. The S-101 implementation,tested in 2014-2015, will transformENCs toricher Electronic Chart Display andInformation Systems. ECDIS combine ENCdata with positioning information, to plotcourseandwarnof forthcomingdangers, andcross-analyse different geo-enabledinformation to provide a rich,multi-layered

situational awareness. Among the mostawaited type of dynamic information areweather data. Already available instandardised GRIB files, they bringadditional graphical layers ofwind, pressure,precipitation, temperature,waveheight, andtidal streams. This rich environmentalinformation canbeused toplan intelligence,surveillance and reconnaissance resources,maximising sensor planning and multi-sensor exploitation.
