## 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.
|
|
|
|
**Parameters**
|
|
|
|
- `geojson` **[GeoJSON][1]** GeoJSON to be centered
|
|
- `options` **[Object][2]** Optional Parameters (optional, default `{}`)
|
|
- `options.properties` **[Object][2]** an Object that is used as the [Feature][3]'s properties (optional, default `{}`)
|
|
|
|
**Examples**
|
|
|
|
```javascript
|
|
var polygon = turf.polygon([[[-81, 41], [-88, 36], [-84, 31], [-80, 33], [-77, 39], [-81, 41]]]);
|
|
|
|
var centroid = turf.centroid(polygon);
|
|
|
|
//addToMap
|
|
var addToMap = [polygon, centroid]
|
|
```
|
|
|
|
Returns **[Feature][4]<[Point][5]>** the centroid of the input features
