Description: The terrain visible from a given point can be determined quick and efficiently by a computer. A FORTRAN subprogram--called VIEWIT--has been developed for this purpose. Input consists of data on elevations, by coordinates, which can be obtained from maps or ae rial photos. The computer will produce an overlay that shows the maximum area visible from an observation point. Both the observation point and the length of line-of-sight are variable. This new technique makes it unnecessary to draw overlays manually.

Keywords: view areas, scene area analysis, computer programs
