In a continuing effort to create industry tools, resources and partnerships that provide value to its end-user, the United States Geological Survey (USGS) has selected MapMart.com to participate in its private partnership program for providing free digital data downloads. These high-resolution, three dimensional data models of the earth’s surface known as SDTS DEMs (also called Spatial Data Transfer Standard Digital Elevation Models) are used for a variety of purposes including three-dimensional visualization and land surface analysis.

The data are also used by engineers, city planners and others who have an application need for three-dimensional data. The data are being released in the robust Spatial Data Transfer Standard (SDTS) format and are available by MapMart.com in other formats compatible with many popular three-dimensional software applications.
