Geographic Information Systems
and Geomatics Remote sensing is quickly becoming only
one source of data into an integrated Geographic Information System (GIS) or Geomatics
Integrated with information from many other sources
Easy to extract useful information and recombine layers
A powerful and integrated analysis and modeling environment
GIS makes remote sensing imagery useful
Integrate GPS/telemetry/RS, databases, telecom, etc.

Mission: To support the development of open source geospatial software and promote its widespread use.
Founding projects (constituted in February 2006): GDAL/OGR, GeoTools, GRASS GIS, Mapbender, MapBuilder, MapGuide Open Source (Autodesk), MapServer, OSSIM
Since Feb 2008: GRASS (and others) are official members
Motivation: More that 200 GFOSS projects worldwide... … need for selection and organization: User oriented!

GRASS GIS and QGIS QGIS Geodata Viewer with GRASS Toolbox, GPS Support and plugins...
http://qgis.org
FOSS Anyone can play
Open source makes for transparency, all can contribute and share
Free as in lunch, free as in open
Allows for free knowledge and technology sharing
We are in charge of development
We can develop specific tools
Not at the mercy of commercial vendors
Students can take tools with them after they leave school, continue collaboration
Extend collaborations around the world
Open Source QGIS/GRASS/R are all open
source, free, and in Spanish
There are many learning resources online
The (excellent) tutorials by Scott Madry walk you through these, and is also in the public domain:

Share, create your own course, develop your own tools, etc.
Let’s work together!
