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
