Abstract
A terrain profile for executing terrain following flight is generated using a minimal volume of digital terrain elevation data (DTED) information. By limiting the amount of information considered in generating the terrain profile, the computational time and resource requirements for terrain profile generation are reduced, but without comprising the integrity of the terrain profile generated. The sample region is limited by limiting the width of sample regions according to expected use including most likely terrain following flight command data, potential unexpected flight path deviation, and long range terrain following flight data.
