在英国,如何根据GPS坐标找到地址?

GPS仅限于返回您所在位置的纬度和经度坐标。

要将这些坐标解析为地址,需要使用外部数据源。将地理坐标转换为地址的行为通常被称为 reverse geocoding .

有一些免费的反向地理编码服务,例如 that offered within the Google Maps API . 但是,请确保您阅读并理解 Terms of Use 在使用此类服务之前。

例如,您可以使用以下HTTP请求使用Google Maps API进行反向地理编码:

简单CSV:

http://maps.google.com/maps/geo?q=40.756041,-73.986939&output=csv&sensor=false

返回:

200,8,"601-699 7th Ave, New York, NY 10036, USA"

更复杂的XML:

http://maps.google.com/maps/geo?q=40.756041,-73.986939&output=xml&sensor=false

返回:

<kml xmlns="http://earth.google.com/kml/2.0"><Response> 
  <name>40.756041,-73.986939</name> 
  <Status>

只需更改 q 参数与您的 latitude,longitude .

请注意,免费版的GoogleMapsAPI每天对每个IP地址有15000个请求限制。( Google Maps API FAQ )

如果你计划大量使用谷歌的反向地理编码服务,你可能会考虑使用 Premier edition of the Google Maps API .

“Premier API自动随附” advanced geocoding capabilities with greater volume and speed “,因此,标准API的限制应该被新配额取代。

作为附加说明,根据一条 unofficial source (2008年4月)Premier API的成本为每年10000美元。

你可以使用各种免费服务,比如谷歌提供的服务,从一些GPS坐标中反向地理编码(技术术语)一个地址。我强烈建议使用他们的API,这里提供完整的文档:

http://code.google.com/apis/maps/documentation/services.html

谷歌 Geolocation Network Protocol 可能会帮助我 认为 我上次尝试的时候,它在英国的一些地方工作。

顺便说一句,这项法令调查刚刚发布了他们的数据,许可证确实很松,我认为他们也有一个网络服务。你可能想看看。

openstreetmap(志愿者创建的免费开放源代码世界地图)使用的是nomingim,看起来非常好。见
