## 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]&lt;([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]&lt;[LineString][5]>** collection of line segments
