Overview
• Benefits of Standards• Business of Open Source Software• Open Data availability and licences
Benefits of Standards
• Interoperability between agencies and devices.
• Future proof• Reduced cost
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
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

• Open Source costs reduces over time
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

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
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
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.
