the usgs does have ``maps on tape''. (is that similar to ``girls on film''?) they have a variety of different types. one type is essentially like a topo with only contour elevation lines (these are called "digital elevation models"). the other types are like topos but without the contour elevation lines; i.e. roads, railroads, buildings, rivers, lakes, city/county/state/etc. boundaries, etc. the address of the main office is national cartographic information center u. s. geological survey 507 national center reston, virginia 22092 (703) 860-6045 there are regional offices; you should ask these folks for the local ncic. when you talk to the people at the local ncic you will need to get them to send you the ``user's guides'' that explain the format that the tapes are written in; i recieved five separate items (zerox copies).
