# @turf/line-chunk ## lineChunk Divides a [LineString][1] into chunks of a specified length. If the line is shorter than the segment length then the original line is returned. **Parameters** - `geojson` **([FeatureCollection][2] \| [Geometry][3] \| [Feature][4]<([LineString][5] \| [MultiLineString][6])>)** the lines to split - `segmentLength` **[number][7]** how long to make each segment - `options` **[Object][8]** Optional parameters (optional, default `{}`) - `options.units` **[string][9]** units can be degrees, radians, miles, or kilometers (optional, default `'kilometers'`) - `options.reverse` **[boolean][10]** reverses coordinates to start the first chunked segment at the end (optional, default `false`) **Examples** ```javascript var line = turf.lineString([[-95, 40], [-93, 45], [-85, 50]]); var chunk = turf.lineChunk(line, 15, {units: 'miles'}); //addToMap var addToMap = [chunk]; ``` Returns **[FeatureCollection][2]<[LineString][5]>** collection of line segments [1]: https://tools.ietf.org/html/rfc7946#section-3.1.4 [2]: https://tools.ietf.org/html/rfc7946#section-3.3 [3]: https://tools.ietf.org/html/rfc7946#section-3.1 [4]: https://tools.ietf.org/html/rfc7946#section-3.2 [5]: https://tools.ietf.org/html/rfc7946#section-3.1.4 [6]: https://tools.ietf.org/html/rfc7946#section-3.1.5 [7]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number [8]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Object [9]: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String [10]: 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.
