National Geospatial Program


The mission of the National Geospatial Program is to provide National topographic information to advance science, support government, enlighten citizens, and enable decision making. The NGP provides a foundation of digital geospatial data representing the topography, natural landscape, and manmade environment of the United States. Accessible through The National Map Data Download, customers can incorporate NGP geospatial products and services into their decision making and operational activities.

Semantically enabling map projections knowledge

Map projections are an area of cartography with a firm mathematical foundation for their creation and display providing a basis for a knowledge representation. Using only variations on a single equation set, an infinite number of projections can be created, but less than 100 are in active use. Because each projection preserves specific...
