openlayer3计算两点之间的距离
openlayer3计算两点之间的距离
对应的openlayers的版本为3.7.
主要用的接口是ol.Sphere.haversineDistance([x1,y1],[x2,y2]);
4326坐标系中计算两点距离的方式为:
var wgs84Sphere = new ol.Sphere(6378137);
wgs84Sphere.haversineDistance(C1,C2);
示例为:
var wgs84Sphere = new ol.Sphere(6378137);
wgs84Sphere.haversineDistance([120.21592590991689, 30.210793016606],[120.21670777384473, 30.211168525868086]);
