Impact of Digital Terrain Elevation Data (DTED) Resolution on TerrainVisualization: Simulation versus Reality

摘要

This study provides evidence of the influence of DTED resolution (in regions withdifferent terrain roughness) on Army terrain data applications. The report documents results of the U.S. Army Topographic Engineering Center's DTED resolution analysis including extensive field work and terrain visualization undertaken to investigate DTED integrity in comparison to the actual terrain. Finally, the report offers conclusions reguarding DTED support for Army tactical and simulation applications.
