Visible Area: Field Of View

Visible Area: Field of View shows what can and cannot be seen from any location on Earth. Map visibility using real elevation data, check the line of sight between two points and plan the light at any viewpoint. Plan, explore and analyze terrain with clear visual tools, on flat maps or in 3D.
