[comp.graphics] USGS computerized maps

I talked with some map developers at the Menlo Park branch today.
There are eventual plans to distribute digitised maps, but nothing currently
in place.  I sometimes use use such data but obtain it informally from the
developer or researcher.

The Menlo Park and Reston branches got on the internet last, but I'm not
aware of any ftp'able databases.

The 3-6-89 Government Computer News reports the Defense Mapping Agency will
sell three types of digitized maps later this year as a set of 400-500 CD-ROMS.
These include (1) World Digital Terrain Elevation Data (raster),
(2) Digital Features Polygonal (roads, rivers, etc.) and (3) Digital Features
Raster.
