Google Maps API V3：如何获取区域边界坐标（折线）数据？ [英] Google Maps API V3: How to get region border coordinates (polyline) data?

问题描述

我试图从Google地图获取（指定）区域边界作为GMaps坐标（以形成多段线）。这在某种程度上可能吗？ （来自maps.google.com或我自己的域名中的GMaps）。

使用专用工具手动绘制/勾勒区域（如 http://www.birdtheme.org/useful /v3tool.html ），但覆盖大范围的准确性是一大堆工作。
在这种情况下，绘制自己的答案不是一种选择。

示例：

1. https://maps.google.com/ - >输入Uusimaa ，芬兰


2. 您可以看到勾勒出想要的区域的粉红色边框


3. 该边框是我需要坐标

要求：

• 提取区域数据坐标（如果可用）来自给定的搜索（如示例所示）


• 如果以前是不可能的，则需要源于芬兰Uusimaa地区的精确地图（原始Google搜索没有得到所需结果）。 这个问题正在成为常见问题解答。查看对这些问题的回复：
  
  

  添加搜索区域大纲谷歌地图结果

  
  
  

  谷歌已经开始突出粉红色的搜索区域。此功能是否可在Google Maps API 3中使用？

  
  

  I'm trying to get (specified) region borders as GMaps coordinates (to form a polyline) from Google Maps. Is this possible in some way? (either from maps.google.com or my own GMaps in my own domain).

  Note: I know you can draw/outline regions manually with tools intended for it (like http://www.birdtheme.org/useful/v3tool.html), but covering a large region ACCURATELY is a ton of work. The draw-it-yourself answer is not an option in this case.

  Example:

  1. https://maps.google.com/ -> type in "Uusimaa, Finland"
  2. You can see the pink-ish border that outlines the wanted region
  3. That border is the polyline that I need the coordinates of

  Requirements:

  • Extract the region data coordinates (if available) from a given search (as in the example)
  • If the previous is not possible, a source to an ACCURATE map of the region "Uusimaa, Finland" is required (plain googling did not yield needed results).

  解决方案

  This is becoming a FAQ. See the replies to these questions:

  Add "Search Area" outline onto google maps result

  Google has started highlighting search areas in Pink color. Is this feature available in Google Maps API 3?
