Mike,
Thanks
for the reply. I need data for both Savannah and Macon Georgia. I've
contacted the GIS people at both city websites and am waiting for a
reply. I'll see what happens...

"buildings" or "structures" seems to be the common name for map or data layers... I generally ask for "edge of pavement" and "building footprint" for this sort of map.

As to sources: If you're lucky, the city will have something. Sanborn has it for a whole lot of places, but won't license it for derivative for-sale products (i.e. maps you sell to other people).

We usually deal on a case-by-case basis, and often have to cobble together from a lot of often very out-of-date sources, and update from aerial imagery. The good news is, for a restaurant guide, a missing gable-end here and there won't destroy the map. Generalization is not a big issue.

Another nominal reference I have heard/used are engineering "planimetrics." In our area these are CAD files that have most everything digitized (curbs, trees, street lanes, etc.). LIDAR is also adept at deriving building footprints and might be another (desperate) search avenue. Checking with the GIS folks is a great start. Good luck!
