MICRODEM is a freeware microcomputer mapping program written by Professor Peter Guth of the Oceanography Department, U.S. Naval Academy. MICRODEM displays and merges digital elevation models, satellite imagery, scanned maps, vector map data, and GIS databases. It requires a 64 bit version of Windows; an older version, which is not being updated, runs on 32 bit operating systems. You may freely use MICRODEM with no restrictions.
