- Yes, such a product exists, and you used to be able to get it from
- MacZone or MacWarehouse, but I (in my own inimitable way) have totally
- forgotten the name. But I suppose that you could call them and see...
- Also, the US Geological Survey (the guys that publish almost all
- government maps) produce several CDs worth of map data -- mostly Digital
- Line Elevation Models, and related stuff. The one system I looked at was
- (unfortunately) on a PC, so I don't know if they are Mac-compatible
- (although I suspect that if you find the proper dealer/company, they'll
- find a way). Anyway, the one system was a government production and
- offered various levels of zoom, overlays, and stuff like that.
- However, with the exception of those maps covering cities, you'll
- probably have to settle for less detail than what you would find on the
- average 7.5" 1:24,000 topographic quadrangle.
- If you really can't find a private company, try talking to your local
- Government Documents Librarian at the nearest Government Depository. At
- the very least, they can point you at relevant USGS & DMA products.
-
- Also, see if you can't find any of those LOTUS:Homes, or
- LOTUS:Marketplace CDs (some have been discontinued due to public protest).
- And finally, you might try tracking down something we in the map biz call
- the TIGERFile: it is a set of CDs that integrate topographic & planimetric
- map data with the latest census results for the area being looked at -- so
- you can slap down a "Per Capita Income" overlay on top of the regular map
- display, etc...
