Programs used for simulating scenarios involving aircraft and ground sites frequently need some type of terrain model and an algorithm to determine when masking occurs between two points. This paper describes three different terrain models and compares them. Each model was implemented on the same computer and several trials using identical flight paths were executed to derive these results. The comparison shows (1) how closely the different models match the results of each other, (2) the efficiency of each model in terms of processing time, and (3) the size of data files necessary to represent a region of terrain for each model.
