Cloud and open source GIS

The Currency of your data• Automating Change

Management• Information where and when it

is required• Flexible digital delivery• Data Accuracy Improvement• Do you trust your Data enough

to share it?

5 Business Drivers

• SaaS, IaaS, PaaS, Web 2.0 / 3.0, Peer to Peer• Addressing and Adapting change and to change

The World has to be on the Cloud

• Instantaneous, Online Response from Inter-continental companies• Digital Supply Chain across Global companies / across the globeThe World is Flat

• Environmental Compliance• Reduce your own and your companies Carbon FootprintThe world is green

• Consumers and Workforce - always on - connected anywhere• Increased demand and expectation for servicesThe World is Mobile

• Energy and Cost Efficient Computing and Data Centres• Flatter Budgets require Efficiencies CAPX and OPEX

The World of Low Cost ICT

Effective Communication

• Clear Messages• Reduce Complexity• Don’t have opinions on

everything• Good and Bad News

Security is changing

• Security has to be appropriate• Security has to be measured • Can have things so secure that they are

unusable.

Cloud / Open is forcing ChangeWith or Without the Owners / Shareholders

So far ICT has not fundamentally changed government

• 1990s: lCT expected to make government more transparent, efficient and user oriented

• 2005+: disillusion as bureaucracy still in existence

• Can Cloud Help?

why is crowd sourcing important?

Crowd Source – Group Collaboration is more powerful than individual achievement

Typical Individual effort

many hours, one map2

why is open source important?

"Given enough eyeballs, all bugs are shallow."

- Eric S. Raymond, co-founder of the Open Source Initiative

What is Cloud?

A pool of highly scalable, abstracted infrastructure, capable of hosting end-customer applications, that is billed by consumption.

What has Cloud ever done for GIS?

Apart from Scale, Enterprise Mapping, Open Data, Standards, Google, API’s, Open Street Maps, Map Servers,

GIS - More than just Location, Spatial Analysis and wider adoption now possible

Why do Government use GIS• Massive demand for timely, relevant information — “picture says a

1000 words” • Support decision making

– Provide users with all the information required to make an informed decision.– Ability to integrate vast amounts of data within one View (Mashup)– Exploit visualisation techniques to present information according to user

preference (Raster, vector, 3D, tabular etc) – Visualise /identify patterns/trends etc – Personalisation– Mobile

The Data Underworld

Massive network of services: water, sewage, drains … Need to know asset location for planning and maintenance Many databases, varying accuracy and provenance Context

Ongoing street openings p.a. Safety!

Why Use Open Source GIS?

1. Marketable skillsIn this ever-changing job market it is a huge benefit to be able to bring a total GIS package to the table

2. Supported by huge development & support community Community is very passionate about helping each other but and continually improving software

3. Low start-up costsIt is now possible to install a complete GIS stack without paying a cent - LEGALLY

4. SecurityArguably more secure than proprietary software Backed by large development communityBugs are found and fixed quickly

Why Use Open Source GIS? (cont’d)

5. Works on all major platforms (Mac, Linux, Windows)6. Complimentary business model vs linear (see next two slides)7. There's nothing missing

Desktop GIS, Spatial Database Storage, Server...Tons of analysis tools (No licensing worries)Community developed add-ons

8. Works with existing GIS dataImport .shp files, most major formatsExport to most major formatsArcSDE now connects to PostGIS (OS Database)

9. No file format lock-in 10. Did we mention FREE?

Potentially save enough money on software to save jobs

The Stack

..in another form..

PostgreSQL + PostGIS

PostgreSQL is a powerful, open source object-relational database system

A true spatial databaseConforms to Open Geospatial Consortium standards*ArcSDE can connect to itNew to ArcGIS Server 9.3Secure storage for both spatial and non spatial dataColumn level permissions granularity PostGIS "spatially enables" the PostgreSQL server, allowing it to

be used as a backend spatial database for (GIS), much like ESRI's SDE

*The Open Geospatial Consortium, Inc.® (OGC) is a non-profit, international, voluntary consensus standards organization that is leading the development of standards for geospatial and location based services.

GeoServerOutputs: WMS, WFS, KML, GeoJSON, GeoRSS, more..

Share and edit geospatial data

Open standards allow publishing from any major spatial data source including: shapefiles, SQL Server, PostGIS, DB2, Oracle, WFS, TIFF Images, MySQL

Integrates with existing API's (Google, yahoo, etc.)

Connects to ArcGIS Server

WMS can be easily added into existing ArcMap .mxd's

http://geoserver.org/display/GEOS/Welcome

GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards…GeoServer is the reference implementation of the Open Geospatial Consortium (OGC) Web Feature Service (WFS) and Web Coverage Service (WCS) standards, as well as a high performance certified compliant Web Map Service (WMS). GeoServer forms a core component of the Geospatial Web.

OpenLayers

JavaScript Library, including API

Similar to Google Maps API

Makes building dynamic mapping webpages VERY easy

Provides the tools needed to easily add a map to a webpage

Allows overlaying your own data

Can display map tiles and markers loaded from any source

http://openlayers.org/

OpenLayers: http://www.openlayers.org/ OpenLayers makes it easy to put a dynamic map in any web page. It can display map tiles and markers loaded from any source…OpenLayers is a pure JavaScript library for displaying map data in most modern web browsers, with no server-side dependencies. OpenLayers implements a (still-developing) JavaScript API for building rich web-based geographic applications, similar to the Google Maps and MSN Virtual Earth APIs, with one important difference -- OpenLayers is Free Software, developed for and by the Open Source software community.
