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点FeatureCollection，并返回从FeatureCollection最接近参考的点。这个计算是测地线的。

参数

参数	类型	描述
targetPoint	Coord	the reference point
points	FeatureCollection <Point>	against input point set

返回

Feature <Point> - the closest point in the set to the reference point

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);
