Re: Free GIS for realtime data and 3D visualization?

Hi Peter
for your WMS Question i recommend TileCache
(http://labs.metacarta.com/wms-c/) on top of your WMS and using
mapbuilder (http://docs.codehaus.org/display/MAP/Home) (which
support/include Openlayer (http://openlayers.org/)) for performant WMS
caching.
Kind regards
Johannes
