Presets

A viewshed marks every point visible from an observer, hidden behind intervening ridges. Scanning outward, a point is seen only if its angle above the horizontal exceeds every closer obstacle — so terrain shadows fall behind hills. Raising the observer reveals far more. It is essential for siting cell towers, wind turbines, scenic overlooks, and military positions.

Governing equation

Reading this result: At 10 m the observer sees over closer bumps but taller ridges still cast blind spots — coverage lands near 0%.

About this simulation

The full Viewshed tool models a delivery zone with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
