  • Some remarks on this yearsIntergeo trade fairHaving returned from this years Intergeo trade show, a number of things caught myeye. First of all, the number of acquisitions in the industry which resulted in largebooths on the exhibition floor of big companies with smaller, local parties that areowned by the big guys. But that does not mean there are no small, interesting com-panies that do stuff that is promising for the future. On the contrary, my interestalways goes out to the OSGeo Park, where a number of small booths are combinedwith open source projects. Every year I see new initiatives happening that are sharedwith the audience. That these initiatives are no longer something that is happeningon the margins of the industry, is proven by the interest shown in them by the bigguys, or a major event such as FOSS4G.

    Mobile mapping is a technology that seems to have reached its peak and is nowbeing replaced by a new trend, namely UAVs. In this issue there are some contribu-tions on this topic that have gained a lot of attention in both the academic worldand the industry itself. While still an interesting and relevant topic, I noticed lessattention to mobile mapping systems on the exhibition floor than at last yearsIntergeo.

    The presence by Google at the exhibition was to be expected, since their GoogleEarth Builder cloud platform is meant for organizations who want to upload theirdata into the cloud. It will be interesting to follow where exactly this will take Googlein the geospatial market, since their services and infrastructure are meant as anadd-on to an already existing GIS infrastructure. But nonetheless, its a move thatcould prove to be interesting, although Google is known for trying out many thingsand not always succeeding in the long run.

    Coming back to my first point about acquisitions, I noticed a trend where the wholecycle of data capture up to the final end product is now being handled by a num-ber of companies operating under the same umbrella or mother company (excep-tions aside, such as Esri). Hardware and software are being integrated and differ-ent flavors are available for different applications, in the case of Z/I Imaging andLeica Geosystems.

    All in all, this years Intergeo once again was a good indication of how the industryis doing. For those of you who werent there to witness it, theres a review of theevent in this issue, as well as a series of specialized contributions that show that theindustry as a whole is moving forward at a fast pace.

    Enjoy your reading,

  • Blom have a long history of owning and operating a range of digital cameras and sensors acrossEurope. Traditionally, these instruments would be used independently, even if multiple data formatswere required. However, the demand for higher quality resources, and the need for improved captureefficiency, has seen the long established techniques of aerial surveying put under the microscope. Onemethod to emerge is to use aircraft with dual sensor capabilities. In early, 2011 Blom UK adapted oneof their aeroplanes to enable simultaneous data capture with their Vexcel large format digital cameraand Optech ALTM LiDAR system.

    The Second HoleCutting a hole into the fuselage of an aircraft is not as simple asone may initially think, especially if the plane already contains alarge survey hatch. Before the hole can be cut several things needto be considered. Will the control cables that run under the cabinfloor need to be rerouted? What is the strength and air worthinessof the plane and how many alterations will be required? What arethe logistics of fitting the equipment and operators into the cabinand will everything fit? Lastly, timescale and costs need to be con-sidered. How long will the plane be out of service and how muchwill it cost, both in down time and in parts and labour?

    The original concept was to add a second full size survey hatch.Following many discussions it was deemed that, with the engineer-ing taking up to six weeks, this would be too expensive. More impor-tantly, it became apparent that a full size hole was not actuallyrequired. The ALTM head is a much smaller unit than the digital cam-era so it does not require such a large hole. It could, in fact, utilisethe existing Nav-Sight hole.Before the advent of GPS, nav-sights were used by operators of largeformat film cameras to ensure the camera was taking pictures at therequired rate and over the correct location. The nav-sight sat in frontof the operators seat and required a small hole in the aircraft floor
