Range 400 (Twentynine Palms)
Digital Orthophoto Mosaic
1 meter Digital Elevation Model
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).
Sited in a box canyon, Range 400 is used to conduct company-level live-fire training in a deliberate assault against prepared defensive positions.
The first and highest resolution data set represents Range 400 at the US Marine Corps Air Ground Combat Center in the Mojave Desert at Twentynine Palms, California.
