I have added DEM2GeoEG as Public Domain to FreeGIS.

I can't access the website.

This is indeed _no_ Free Software!

However, you cannot sell the GeoTransform package itself, and all derivative works that you make on the package must be published openly under the terms of the original license."

I have added GeoVRML to FreeGIS with the note that it depends on a
non-free software module. Perhaps we will find someone
who makes GeoVRML independent of GeoTransform.

With these two added, FreeGIS now has now reached exactly 100 entries!
Thanks to all who contribute to FreeGIS and of course to all who 
contribute to the actual software packages!
