DESCRIPTION

This transmittal is a high-resolution data set that represents Range 400 (sited in a box canyon) at the US Marine Corps Air Ground Combat Center (MCAGCC) in the Mojave Desert at Twentynine Palms, California.

.

The primary data source is a 1-meter digital elevation model (DEM) and associated orthophoto generated from large-scale aerial photography by Raye Norvelle at the US Army Topographic Engineering Center (TEC). Based on extensive ground control, the vertical accuracy of this DEM is estimated to be an extraordinary 0.15 meter root-mean-square-error (RMSE).

The DEM extends over an area of 2.1 km East-West by 3.2 km North-South.

Sited in a box canyon, Range 400 is used to conduct company-level live-fire training in a deliberate assault against prepared defensive positions.

This data set was put to use at Twentynine Palms under the DARPA Leathernet Project. Since 1995, it remains a benchmark for high-resolution terrain representation of a desert area.

Both gridded and polygonal data sets are provided in the download.
