Digital Map Generator (DMG).

Digitial equipment that produces map video, and sometimes contains TRN; uses Digital Terrain Elevation Data and Digitized Feature Analysis Data; Displays reconstructed digital map data, aeronautical charts or photographs. The digital map data can be annotated with natural and man-made (point and linear) features as well as threats. A Terrain Referenced Navigation algorithm correlates altitude readings with digital map data to provide position data. Digital Terrain Elevation Data (DTED). On a digitial map, data for elevation of terrain; DTED is usually provided by Defense Mapping Agency; Compare: Digitized Feature Analysis Data; Digitized Feature Analysis Data (DFAD). On a digitial map, data for cultural features such as buildings and roads; DFAD is usually provided by Defense Mapping Agency; Compare: Digital Terrain Elevation Data;
