如何在一个位置的所有方向上使用5公里的点，对Google API进行地理编码？ [英] How to take 5 km points in all directions of a location, geocoding google api?

问题描述

好的，我有这些线：

  55.623151，8.48215 
  

我希望看到地理编码距北，南，东，西5公里，地点位于^以上。

我该怎么做？

解决方案

如果您使用Google Maps API v3，如下所示：

将Geometry库包含到您的网页中，以供 Spherical Computations ：

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

然后您可以计算：

  var point = new google.maps.LatLng（55.623151，8.48215）; 
 var spherical = google.maps.geometry.spherical; 
 var north = spherical.computeOffset（point，5000，0）; 
 var west = spherical.computeOffset（point，5000，-90）; 
 var south = spherical.computeOffset（point，5000，180）; 
 var east = spherical.computeOffset（point，5000，90）; 
  

您可以查看在jsfiddle上运行版本。

Ok so i have these cords:

55.623151, 8.48215

I would like to see the geo codes 5 km from north, south, east, west from this geo location above^.

How can i do this?

解决方案

If you use Google Maps API v3, then you would proceed as follows:

Include the Geometry library into your Web page for Spherical Computations:

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

Then you can compute:

var point = new google.maps.LatLng(55.623151, 8.48215);
var spherical = google.maps.geometry.spherical; 
var north = spherical.computeOffset(point, 5000, 0); 
var west  = spherical.computeOffset(point, 5000, -90); 
var south = spherical.computeOffset(point, 5000, 180); 
var east  = spherical.computeOffset(point, 5000, 90); 

You can check a running version on jsfiddle.
