Package Exports

@turf/nearest-point-to-line
@turf/nearest-point-to-line/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@turf/nearest-point-to-line) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@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
- options.units string unit of the output distance property (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
