@turf/nearest-point-to-line

nearestPointToLine

Returns the closest point, of a collection of points, to a line. The returned point has a dist property indicating its distance to the line.

Parameters

points (FeatureCollection | GeometryCollection<Point>) Point Collection
line (Feature | Geometry<LineString>) Line Feature
options Object? Optional parameters (optional, default {})
- options.units Units unit of the output distance property. Supports all valid Turf Units. (eg: degrees, radians, miles, or kilometers) (optional, default 'kilometers')
- options.properties Object Translate Properties to Point (optional, default {})

Examples

var pt1 = turf.point([0, 0]);
var pt2 = turf.point([0.5, 0.5]);
var points = turf.featureCollection([pt1, pt2]);
var line = turf.lineString([[1,1], [-1,1]]);

var nearest = turf.nearestPointToLine(points, line);

//addToMap
var addToMap = [nearest, line];

Returns Feature<Point> the closest point
