JarCastingturf-centroid
turf centroid module
turf.centroid(features)
Takes one or more features and calculates the centroid using the arithmetic mean of all vertices. This lessens the effect of small islands and artifacts when calculating the centroid of a set of polygons.
Parameters
| parameter | type | description |
|---|---|---|
features |
Feature,FeatureCollection | input features |
Example
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
Installation
