pointToLineDistance

Returns the minimum distance between a Point and a LineString, being the distance from a line the minimum distance between the point and any segment of the LineString.

Parameters

• pt (Feature<Point> | Array<number>) Feature or Geometry

• line Feature<LineString> GeoJSON Feature or Geometry

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

  • options.units string can be anything supported by turf/convertLength (ex: degrees, radians, miles, or kilometers) (optional, default "kilometers")
  • options.method string wether to calculate the distance based on geodesic (spheroid) or planar (flat) method. Valid options are 'geodesic' or 'planar'. (optional, default "geodesic")

Examples

var pt = turf.point([0, 0]);
var line = turf.lineString([[1, 1],[-1, 1]]);

var distance = turf.pointToLineDistance(pt, line, {units: 'miles'});
//=69.11854715938406

Returns number distance between point and line
