Description: A practical review of coordinate systems.

A practical review of how to identify and specify coordinate systems for applications built on PROJ.4, use of EPSG codes or use of OGC Well Known Text. Detailed examples will be given for a variety of coordinate system, including examples of how it would be used with applications such as MapServer, GRASS, GDAL/OGR, and PostGIS. However, the techniques should apply to any application built on the same representations.
