Point in Polygon for a territory carve
Simulate a territory carve live in your browser. This runs the real Point in Polygon solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.
Controls
Is a point inside a shape? The ray-casting algorithm shoots a ray from the point in any direction and counts how many polygon edges it crosses: an odd number means inside, an even number means outside. It is the math behind geofencing — triggering an alert when a phone or vehicle enters or leaves a region — and behind hit-testing in graphics. Drag the point, or click anywhere to move it there.

About this simulation
The full Point in Polygon tool models a territory carve 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.
