我需要知道预定点在海里还是在陆地上 [英] I need to know the predefined point is in the sea or on the land

问题描述

我有一个系统，用户放置一些坐标（纬度/经度），我需要检查指定的坐标是否在海中。有什么服务可以给我答案吗？或者是否可以使用Google地图来完成这项工作。

您可以使用 Google地图地理编码API 。

，响应的result_type将类似administrative_area。如果您身处海中，则回复将为natural_feature。

以下是两个例子：

• 第一个是0,0点，位于大西洋中部： http://maps.google.com/maps/api/geocode/xml?address=0,0&sensor=false


• 第二个位于撒哈拉沙漠中部20.012065，-6.82251： http://maps.google.com/maps/api/geocode/xml?address=20.012065,-6.82251&sensor=false

编辑：更多回复评论的例子：

• 这一点位于英国声称的海域，在12英里的范围内。它显示为natural_feature： http：/ /maps.google.com/maps/api/geocode/xml?address=50.801541,0.424519&sensor=false


• 这一点位于苏必利尔湖，在雷湾。它显示为natural_feature： http： //maps.google.com/maps/api/geocode/xml?address=48.23565,-86.981506&sensor=false

I have a system where users put some coordinates (latitude/longitude), I need to check if specified coordinates are in the sea or not. Is there any service that could give me the answer. Or is it possible to do this using google maps.

解决方案

You can use the Google Maps Geocode API.

If your address is in land, the result_type of the response will be something like "administrative_area". if you are in the sea, the response will be "natural_feature".

Here are two examples:

• The first is the 0,0 point, in the middle the the Atlantic Ocean: http://maps.google.com/maps/api/geocode/xml?address=0,0&sensor=false
• The second is located at 20.012065,-6.82251, in the middle of the Saharan desert: http://maps.google.com/maps/api/geocode/xml?address=20.012065,-6.82251&sensor=false

Edit: Some more examples in response to comments:

• This point is located in the sea claimed by UK, within the 12 miles limit. It shows as "natural_feature": http://maps.google.com/maps/api/geocode/xml?address=50.801541,0.424519&sensor=false
• This point is located in the Lake Superior, in the Thunder Bay. It shows as "natural_feature": http://maps.google.com/maps/api/geocode/xml?address=48.23565,-86.981506&sensor=false
