Web Mapping Illustrated: Using Open Source GIS Toolkits

Compiling PostGIS from source code isn't covered here. Source code can be downloaded from the PostGIS web site at http://postgis.refractions.net/download.php. This site includes hourly snapshots of source code from the CVS repository, as well as official releases. Source RPMs are also available.

Compilation instructions are provided as a README file that comes with the source:
