Point in Polygon
Test GeoJSON points against Polygon or MultiPolygon boundaries and report which polygon contains each point.
Input
Boundary points count as inside by default. The first input supplies points and the second supplies polygons.

Understanding Point in Polygon
Spatial relationships and derived geometry
Test GeoJSON points against Polygon or MultiPolygon boundaries and report which polygon contains each point.
Point in Polygon evaluates where features lie relative to one another or creates geometry from that relationship. Geometry validity, boundary rules and compatible coordinate assumptions control the result.
How to verify the operation
Boundary points count as inside by default. The first input supplies points and the second supplies polygons.
Review Point in Polygon with feature counts, empty outputs, boundary cases and a few known examples. Confirm units and CRS assumptions before treating the result as authoritative.
