The (US) Bureau of Census has a text encoding of city maps called
"GBF/DIME".  Basically, it consists of records of line information which
can be also be used as bounds for areas.  For more information, contact
	Data User Services Division
	Bureau of the Census
	Dept. of Commerce
	Washington, D.C.  20233

The Geological Survey is also starting to encode map data in computer form.
Contact the USGS in Reston, VA  22092.
