pointToPolygonDistance

Description

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

Name	Type	Description
point	Feature<Point> | Point | Position	Input point
polygonOrMultiPolygon	Feature<Polygon | MultiPolygon> | Polygon | MultiPolygon	Input polygon or multipolygon
options	Object	Optional parameters (default {})
options.units	Units	Units of the result e.g. "kilometers", "miles", "meters"
options.method	"geodesic" | "planar"	Method of the result

Returns

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