GeoJSON Centroid
Calculate the centroid of all vertices in a GeoJSON input and return it as a Point feature.
Input
A centroid can fall outside concave polygons; use Point on Surface when the point must lie on the feature.

Understanding GeoJSON Centroid
Spatial relationships and derived geometry
Calculate the centroid of all vertices in a GeoJSON input and return it as a Point feature.
GeoJSON Centroid 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
A centroid can fall outside concave polygons; use Point on Surface when the point must lie on the feature.
Review GeoJSON Centroid with feature counts, empty outputs, boundary cases and a few known examples. Confirm units and CRS assumptions before treating the result as authoritative.
