turf-centroid
Advanced tools
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.
Parameters
features
(Feature | FeatureCollection) input featuresExamples
var poly = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Polygon",
"coordinates": [[
[105.818939,21.004714],
[105.818939,21.061754],
[105.890007,21.061754],
[105.890007,21.004714],
[105.818939,21.004714]
]]
}
};
var centroidPt = turf.centroid(poly);
var result = {
"type": "FeatureCollection",
"features": [poly, centroidPt]
};
//=result
Returns Feature<Point> the centroid of the input features
