  2. What is “Open Source”? • “The last bastion of Stalinism…” • Multi-billion dollar industry including servers (20% of all servers are Linux), databases (MySQL will double its revenue to $80 M this year), development platforms (Eclipse has eclipsed nearly all other programming environments) and thousands of open source projects on www.SourceForge.net and elsewhere. • “It’s OK for playing around, but when you really have to do work, you use commercial product X” • “When programmers can read, redistribute, and modify the source code for a piece of software, the software evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing.”- www.OpenSource.org

  3. Some Open GIS Organizations • OGC = Open Geospatial Consortium • Evolved from GRASS Foundation • Sponsored by open and closed source companies • Focused on development of open standards – especially for web services (WFS, WCS, WMS, etc.) • OSGeo = Open Source Geospatial Foundation • New organization focused on supporting and promoting open source geospatial software • Sponsors FOSS4g Conferences (first was last year in Lausanne, Switzerland!)
