HorizonMap

HorizonMap is a tool for visualizing the line-of-sight range from any selected point on the globe. It is especially useful for shortwave radio communication or just finding some nice spots:)

Online version

An online version of the tool is available here.

Options

• Height Offset – the base height of the "eyes" above the ground
• Include Earth's Curvature – includes a simplified simulation of Earth's curvature in the calculations
