OSGeo – Open Source Geospatial Foundation
OSGeo Mission StatementTo 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.

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
