Can anyone point me to an overview of PostGIS and how it is being used???
Bob,
PostGIS provides extensions to PostgreSQL's procedural language and geometric data types so that it can store geo-referenced data, and so that you can query this data using geo-spatial coordinates.
Software like MapServer (web) and Qgis (desktop) use PostGIS to provide data in map applications.
The Refractions site already noted is a good start. The MapServer site is another:
