Pentagon agency creating digital map of the world

Future military operations may use a constantly updated digital "image skin" for a comprehensive map of the world under development by the Pentagon's National Geospatial-Intelligence Agency (NGA).

This week, the NGA sought information from potential contractors to help develop the "orthorectified image skin" that would provide the base layer for the world map. Such a map would give the military a clearer picture of any potential trouble spot where troops would have to operate.

The U.S. Geological Survey defines orthoimagery as "high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability" of a traditional map.

"A key element necessary to support global readiness is the availability of a current and accurate worldwide image base to ensure a common operational picture for all users," the NGA document says.
