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).
