Hi,
I've been workin with ISTAR products. (for 3D urban modelling see
www.geovrml.com for an example of of the city of Monaco, (and for
interactive 3D intervisibility analysis too ..., well, the site is french
... but you'll find lads of pictures ;) ...)). Those products are very good
as far as urban intervisibility is your problem. They're working in the
wireless area, so they've got precise clutter maps, but only for urban
sites. Precision is far under a meter in the plane, and roughly 20 cm in
height impressive
Eric.

I use building city models in my work and have used actual data from all
the
veldors listed below except IStar. (Istar is from Europe and is currently
in progress of flying US Cities)
You can get ortho images, 1m dems with buildings, vector outline files,
canopy dems, etc. Most cities are off the shelf.

Does anyone know of current sources of DEM/Canopy Dem's building heights?
Thanks
