Viewshed maps

Perform viewshed analysis using a loaded grid file with a user-specified transmitter location, height, starting angle and radius. All visible areas from the transmitter location within the selected radius are filled with a user-specified color. Alternatively, choose to display the invisible areas from the transmitter.

Viewshed analysis is useful in many applications, such as determining if mining operations or drill rigs can be viewed from public locations, determining what is visible from trails or roads, and to locate communication towers.
