turf centroid module

Usage no npm install needed!

<script type="module">
  import spatialCentroid from 'https://cdn.skypack.dev/@spatial/centroid';




Takes one or more features and calculates the centroid using the mean of all vertices. This lessens the effect of small islands and artifacts when calculating the centroid of a set of polygons.


  • geojson GeoJSON GeoJSON to be centered
  • properties Object an Object that is used as the Feature's properties (optional, default {})


var polygon = turf.polygon([[[-81, 41], [-88, 36], [-84, 31], [-80, 33], [-77, 39], [-81, 41]]]);

var centroid = turf.centroid(polygon);

var addToMap = [polygon, centroid]

Returns Feature<Point> the centroid of the input features
