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

• line1 GeoJSON any LineString or Polygon

• line2 GeoJSON any LineString or Polygon

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

  • options.removeDuplicates boolean remove duplicate intersections (optional, default true)
  • options.ignoreSelfIntersections boolean ignores self-intersections on input features (optional, default false)

var line1 = turf.lineString([[126, -11], [129, -21]]);
var line2 = turf.lineString([[123, -18], [131, -14]]);
var intersects = turf.lineIntersect(line1, line2);

//addToMap
var addToMap = [line1, line2, intersects]

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