  1. Open StandardsOpen SourceOpen Data Cameron Shorter Geospatial Systems Architect Lisasoft/Terrapages GITA 2007 Geospatial Infrastructure Solutions Conference

  2. Overview Benefits of Standards Business of Open Source Software Open Data availability and licences

  3. Benefits of Standards Interoperability between agencies and devices. Future proof Reduced cost

  4. Standards: Return on Investment 26% overall saving. Low Maintenance and Operation costs outweigh higher implementation costs. Lower transition costs for sharing data. Half the risk. Geospatial Interoperability Return on Investment Study, NASA Geospatial Interoperability Office, April 2005

  5. What is Open Source? Free applications. Free access to source code. Free to extend source code. Examples: Linux (displacing Solaris unix) Apache (used by 70% of worlds web servers) MySQL, Postgres databases

  6. Open Source Geospatial Foundation Open Source Geospatial Software Free Geospatial Data Education

  7. Proprietary vs Open Source

  12. Price comparison Open Source costs reduces over time

  13. Extending Open Source Open design process Align with other developments Contribute improvements back Features are supported and extended Engage Open Source developers Reduce cost and risk

  14. Support & Partners OSGeo Developer register: 80 Organisations for hire http://www.osgeo.org/spd_help Lisasoft/Terrapages in Australia http://terrapages.com/TerraPages/Services/Support.html Autodesk DM Solutions

  15. License misconceptions “Using open source means you have to release the source code for your application, and anything else that touches it.” 40+ different open source licenses GPL – restrictive LGPL - open BSD – anything goes

  16. Australian Data Australian Spatial Data Directory 750 National Datasets Open license 1.5 Million downloads last year Google Maps Free for non-commercial Common Datasets from PSMA Proprietary Open Street Map Community building street maps

  17. Open Data Licenses Move toward Creative Commons Attribution Noncommercial No Derivative Works Share Alike Australia using combination of licenses based on Contract Law. Qld GILF adding options to Creative Commons to cover extra 15% of data requiring royalties.
