# @turf/boolean-crosses ## booleanCrosses Boolean-Crosses returns True if the intersection results in a geometry whose dimension is one less than the maximum dimension of the two source geometries and the intersection set is interior to both source geometries. Boolean-Crosses returns t (TRUE) for only multipoint/polygon, multipoint/linestring, linestring/linestring, linestring/polygon, and linestring/multipolygon comparisons. **Parameters** - `feature1` **([Geometry][1] \| [Feature][2]<any>)** GeoJSON Feature or Geometry - `feature2` **([Geometry][1] \| [Feature][2]<any>)** GeoJSON Feature or Geometry **Examples** ```javascript var line1 = turf.lineString([[-2, 2], [4, 2]]); var line2 = turf.lineString([[1, 1], [1, 2], [1, 3], [1, 4]]); var cross = turf.booleanCrosses(line1, line2); //=true ``` Returns **[boolean][3]** true/false [1]: https://tools.ietf.org/html/rfc7946#section-3.1 [2]: https://tools.ietf.org/html/rfc7946#section-3.2 [3]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean --- This module is part of the [Turfjs project](http://turfjs.org/), an open source module collection dedicated to geographic algorithms. It is maintained in the [Turfjs/turf](https://github.com/Turfjs/turf) repository, where you can create PRs and issues. ### Installation Install this module individually: ```sh $ npm install @turf/boolean-crosses ``` Or install the Turf module that includes it as a function: ```sh $ npm install @turf/turf ``` ### Diagrams ![esri-crosses](diagrams/esri-crosses.gif)
