turf line-chunk module

Usage no npm install needed!

<script type="module">
  import turfLineChunk from 'https://cdn.skypack.dev/@turf/line-chunk';




Divides a LineString into chunks of a specified length. If the line is shorter than the segment length then the original line is returned.


  • geojson (FeatureCollection | Geometry | Feature<(LineString | MultiLineString)>) the lines to split
  • segmentLength number how long to make each segment
  • options Object Optional parameters (optional, default {})
    • options.units string units can be degrees, radians, miles, or kilometers (optional, default 'kilometers')
    • options.reverse boolean reverses coordinates to start the first chunked segment at the end (optional, default false)


var line = turf.lineString([[-95, 40], [-93, 45], [-85, 50]]);

var chunk = turf.lineChunk(line, 15, {units: 'miles'});

var addToMap = [chunk];

Returns FeatureCollection<LineString> collection of line segments
