OSGeo Open Source Geospatial Foundation

• OSGeo Mission Statement
• To support the development of open source
  geospatial software, and promote its widespread
  use.
• OSGeo Goals
• To provide resources for foundation projects -
  eg. infrastructure, funding, legal.
• To promote freely available geodata - free
  software is useless without data.
• To promote the use of open source software in the
  geospatial industry (not just foundation
  software) - eg. PR, training, outreach.
• To encourage the implementation of open standards
  and standards-based interoperability in
  foundation projects.
• To ensure a high degree of quality in foundation
  projects in order to build and preserve the
  foundation "brand".
• To make foundation and related software more
  accessible to end users - eg. binary "stack"
  builds, cross package documentation.
• To provide support for the use of OSGeo software
  in education via curriculum development,
  outreach, and support.
• To encourage communication and cooperation
  between OSGeo communities on different language
  (eg. Java/C/Python) and operating system (eg.
  Win32, Unix, MacOS) platforms.
• To support use and contribution to foundation
  projects from the worldwide community through
  internationalization of software and community
  outreach.
• To operate an annual OSGeo Conference, possibly
  in cooperation with related efforts (eg. EOGEO).
• To award the Sol Katz award for service to the
  OSGeo community.

Desktop Raster/Vector Processing

• GRASS/GDAL/OGR - Data Crunching
• Both Raster and Vector support
• Very powerful tool set (similar to
  ArcINFO/ArcGRID)
• Traditionally Poor GUI, but getting better
• Very fast
• Cross platform

• QGIS/GDAL/OGR Data Viewing/Editing
• Both Raster and Vector support
• Nice GUI
• Cross platform
• QGIS can integrate with GRASS
