@spatial/boolean-overlap

booleanOverlap

Compares two geometries of the same dimension and returns true if their intersection set results in a geometry different from both but of the same dimension. It applies to Polygon/Polygon, LineString/LineString, Multipoint/Multipoint, MultiLineString/MultiLineString and MultiPolygon/MultiPolygon.

Parameters

• feature1 (Geometry | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) input
• feature2 (Geometry | Feature<(LineString | MultiLineString | Polygon | MultiPolygon)>) input

Examples

var poly1 = turf.polygon([[[0,0],[0,5],[5,5],[5,0],[0,0]]]);
var poly2 = turf.polygon([[[1,1],[1,6],[6,6],[6,1],[1,1]]]);
var poly3 = turf.polygon([[[10,10],[10,15],[15,15],[15,10],[10,10]]]);

turf.booleanOverlap(poly1, poly2)
//=true
turf.booleanOverlap(poly2, poly3)
//=false

Returns boolean true/false
