- General open source with a spatial twistBoth Positive and Negative MythsNot trying to convince everyone that open source is better and that they should dump their ESRI licenses
- Lots of ‘open’ terms thrown around, but what do they meanOpen Data – Data licensing modelOpen Standards – Interoperability – WFS/WMS etcOpen Source – Software licensing model
- Lots of historical conflict between open source and proprietary communities
- Bill Gates
- Richard Stallman – Creator of GNU, which is a foundation of LINUX
- If you do a 30 second google search you get images like these
- Let’s try to find some middle ground and look at some myths along the way
- Lot’s of companies base there business around supporting open source productsOpenGeo do work at Landgate
- Does that mean that PostGIS is better than Oracle – NO!
- Scalability – Estimates are that Google has over 1M serversESRI– Over 80 open source components in ArcGISESRI promote a mixed model between open source and proprietary
- It’s about products not softwareWhen you buy an ESRI license you get the software plus………….
- The total product cost needs to be taken into accountDepends on your needs
- Where’s the business model in open source if you give the software away
- Proprietary – Pay for the software, get the other things for free (mostly)Open Source – Get the software for free, pay for the other things
- Community based development = faster development cycle
- There is a full open source stackIntegrates with proprietary stack (mostly)Depends on requirements
