Question

您好我想知道如何在开放层中找到两个标记之间的距离。

var distance = distanceBetweenMarkers(latLon1, latLon2){
//code to find the distance between latLon1, latLon2

}

请帮助我...

Answer 1

从LonLat创建积分并从distanceTo调用Geometry.Point方法[1]。

p1 = new OpenLayers.Geometry.Point(latLon1.lon,latLon1.lat);
p2 = new OpenLayers.Geometry.Point(latLon2.lon,latLon2.lat);
len = p1.distanceTo(p2);
