Package Exports

@turf/line-intersect

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/line-intersect) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@turf/line-intersect

lineIntersect

Takes any LineString or Polygon GeoJSON and returns the intersecting point(s).

Parameters

line1 (FeatureCollection | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) any LineString or Polygon
line2 (FeatureCollection | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) any LineString or Polygon

Examples

var line1 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "LineString",
    "coordinates": [
      [126, -11],
      [129, -21]
    ]
  }
};
var line2 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "LineString",
    "coordinates": [
      [123, -18],
      [131, -14]
    ]
  }
};
var points = turf.lineIntersect(line1, line2);
//= points

Returns FeatureCollection<Point> point(s) that intersect both
