# nearestPoint
Takes a reference point and a FeatureCollection of Features with Point geometries and returns the point from the FeatureCollection closest to the reference. This calculation is geodesic.
取一个参考点和一个具有点几何特征的FeatureCollection
,并从FeatureCollection
返回最接近的参考点的点。此计算是测地线计算。
参数
参数 | 类型 | 描述 |
---|---|---|
targetPoint | Coord | 参考点 |
points | FeatureCollection <Point> | 点集合 |
返回
Feature <Point> - 集合中与参考点最接近的点
示例
var targetPoint = turf.point([112.015826, 36.074031], {"marker-color": "#F00"});
var points = turf.featureCollection([
turf.point([105.142483, 35.834725]),
turf.point([104.772949, 30.963027]),
turf.point([110.907223, 33.09316])
]);
var nearest = turf.nearestPoint(targetPoint, points);
