@turf/boolean-intersects

booleanIntersects

Boolean-intersects returns (TRUE) if the intersection of the two geometries is NOT an empty set.

Parameters

• feature1 (Geometry | Feature<any>) GeoJSON Feature or Geometry

• feature2 (Geometry | Feature<any>) GeoJSON Feature or Geometry

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

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

Examples

var point1 = turf.point([2, 2]);
var point2 = turf.point([1, 2]);
var line = turf.lineString([[1, 1], [1, 3], [1, 4]]);

turf.booleanIntersects(line, point1);
//=false

turf.booleanIntersects(line, point2);
//=true

//addToMap
var addToMap = [point1, point2, line];
point1.properties['marker-color'] = '#f00'
point2.properties['marker-color'] = '#0f0'

Returns boolean true if geometries intersect, false otherwise
