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. Win 32, Unix, Mac. OS) 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 Arc. INFO/Arc. GRID) 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
