[postgis-users] Downloading PostGIS for Windows installer - circular links that lead nowhere?

[Steven De Vriendt]

Dana,

Take a look at the OpenEV toolkit; OpenEV comes with FWTools;
you'll find it here:
http://fwtools.maptools.org/ and here
http://openev.sourceforge.net/index.php?page=features
I don't know if it'll fullfill all of your raster analysis needs, but
it won't hurt
taking a look.

Steven
