# 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.
获取一个或多个Feature,并使用所有顶点的平均值计算质心。在计算一组多边形的质心时,这减少了小岛和人造岛的影响。

参数

参数 类型 描述
geojson GeoJSON GeoJSON to be centered
properties Object an Object that is used as the Feature 's properties

返回

Feature <Point> - the centroid of the input features

示例

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

var centroid = turf.centroid(polygon);
