Understanding Point on Surface
Spatial relationships and derived geometry
Create a representative Point guaranteed to lie on or within the supplied GeoJSON feature collection.
Point on Surface 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
The result is a representative location, not a population-weighted or visual center.
Review Point on Surface with feature counts, empty outputs, boundary cases and a few known examples. Confirm units and CRS assumptions before treating the result as authoritative.
