Digital Production of Landsat Image Maps in the Map Publishing Environment.

摘要

In support of counter narcotics activities the Defense Mapping Agency has begun production of a series of Landsat image maps. Produced at a scale of 1:100,000, these Landsat image maps are compiled from recent Landsat Thematic Mapper scenes. Bands 7, 4, and 2 are combined in a false color composite. Intensification of selected features provides improved topographic detail. The enhanced Landsat imagery is combined with a UTM grid and margin information and compiled and color separated in a digital environment. The Map Publishing Environment (MPE) output is film separates, printed via a large format laser filmwriter. In support of this new production system, a unique development/production environment was created to bring the Government cartographers into direct contact with the system developers in order to facilitate rapid modifications and changes to the application software as necessary.
