A Field Investigation of DTED Suitability for Line-of-Sight (LOS) applications
Abstract
Recent advance in weapon systems and combat simulators have increased the need for higher resolution data for terrain appreciation and three prediction applications. To date, the Defense Mapping Agency's (DMA) Digital Terrain Elevation Data (DTED) Level 1 database, an elevation matrix with 3 arc second or 100-meter post spacing, has been used by most military and Department of Defense(DOD) users when elevation data was required for modeling, simulations or other applications. The advent of the Tactical Terrain Data (TTD)* prototype and its corresponding DTED Level 2 cell (1 arc second spacing or 30-meter post spacing) has afforded joint service users a unique opportunity to compare the two databases in terms of their uses for relevent applications, especially line-of-sight (LOS). A major aspect of the Army's evaluation of the TTD prototype involved a comprehensive comparison of DTED Level 1 vs. Level 2 conducted by the Digital Concepts and Analysis Center (DCAC) at the United States Army Topographic Engineering Center (TEC) Fort Belvoir, VA and the prototype study area Fort Hood, TX.
