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

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.
