Abstract
The conventional method of determining line-of-sight (LOS) between systems on the battlefield in combat models and simulations is via algorithms operating of a grid of elevation posts. Representation of the "micro-terrain" features which are critical to intervisibility forces finer grids to be employed, causing stiff computational and computer memory penalties. A LOS algorithm is proposed that operates directly on a set of elevation contours. This "vector" method is compared to the "raster" method at several levels of resolution within a simple scenario. LOS prediction accuracy, computational workload, and computer memory requirements are compared.
