Consideration of Line-of-Sight LOS conditions has always been an essential aspect of the battlefield. Knowledge of the surrounding terrain and its corresponding elevation has even more implications today in the modern Army. To date, the Defense Mapping Agencys DMA Digital Terrain Elevation Data DTED Level 1 database, an elevation matrix with 3 arc second or approximately 100-meter post spacing, has been used by most military and DOD users when elevation data was required for modeling, simulations or other applications. Recent advances in weapon systems and combat simulators has brought into question the adequacy of DTED Level 1 for terrain appreciation and threat prediction applications, especially LOS. Consequently, the need for higher resolution terrain data e.g, greater than 30 meter post spacing and the ability of differing resolutions of DTED to accurately predict LOS conditions is of great interest to the Armys community.
