谷歌地图 - 如何获得米之间的两点之间的距离？ [英] Google Maps - How to get the distance between two point in metre?

问题描述

我有这些坐标：

 （45.463688，9.18814）
（46.0438317，9.75936230000002）
  

我需要（使用Google API V3，我认为）可以计算这两点之间的距离。我该怎么做？

解决方案

如果您想使用v3 google maps API，请使用以下函数：
注意：您必须将& libraries = geometry 添加到您的脚本源文件中

  < script type =text / javascriptsrc =http://maps.google.com/maps/api/js?sensor=false&libraries=geometry>< / script> 
 
< script> 
 var p1 = new google.maps.LatLng（45.463688，9.18814）; 
 var p2 = new google.maps.LatLng（46.0438317，9.75936230000002）; 
 
 alert（calcDistance（p1，p2））; 
 
 //计算km中
函数的两点之间的距离calcDistance（p1，p2）{
 return（google.maps.geometry.spherical.computeDistanceBetween（p1，p2）/ 1000）.toFixed（2）; 
} 
 
< / script> 
  

I have these coordinate :

(45.463688, 9.18814) 
(46.0438317, 9.75936230000002)

and I need (trought Google API V3, I think) to get the distance between those 2 points in metre. How can I do it?

解决方案

If you're looking to use the v3 google maps API, here is a function to use: Note: you must add &libraries=geometry to your script source

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&libraries=geometry"></script>

<script>
var p1 = new google.maps.LatLng(45.463688, 9.18814);
var p2 = new google.maps.LatLng(46.0438317, 9.75936230000002);

alert(calcDistance(p1, p2));

//calculates distance between two points in km's
function calcDistance(p1, p2) {
  return (google.maps.geometry.spherical.computeDistanceBetween(p1, p2) / 1000).toFixed(2);
}

</script>
