pointToPolygonDistance

Calculates the distance from a point to the edges of a polygon or multi-polygon. Returns negative values for points inside the polygon. Handles polygons with holes and multi-polygons. A hole is treated as the exterior of the polygon.

Parameters

• point (Feature<Point> | Point | Position) Input point

• polygonOrMultiPolygon (Feature<(Polygon | MultiPolygon)> | Polygon | MultiPolygon) Input polygon or multipolygon

• options Object Optional parameters (optional, default {})

  • options.units Units Units of the result e.g. "kilometers", "miles", "meters"
  • options.method ("geodesic" | "planar") Method of the result

• Throws Error If input geometries are invalid

Returns number Distance in meters (negative values for points inside the polygon)
