[osg-users] Public domain/free sources of geospatial data

[Robert Osfield]

Hi All,

I'm starting work on putting together online tutorials for
VirtualPlanetBuilder 1.0, and in this effort really need plenty of
data that users can freely download themselves and run through
osgdem/vpbmaster.   vpbmaster allows VirtualPlanetBuilder to scale up
to handling tens of thousands of source files and terrabytes of data
so it'd be useful to have plenty of data to source to actually tax it
properly.

So suggestions for source data?

Robert.
