如何确定经纬度坐标长上与谷歌地图API第2路 [英] How to determine if lat long coordinates are on a road with Google Maps API v2
问题描述
我已经使用谷歌的地理地址和使用经纬度/长已经得到了地址。我如何确定，如果我在路上呢？基本上，点击测试道路？我目前正在使用的位置经理纬度/经度和GeoAddress是相同的道路，毗邻的道路。
最终解决方案
使用反向通过谷歌地理编码API 的地理编码。
术语地理编码一般指翻译人类可读 地址到地图上的一个位置。做相反的过程， 平移地图上的一个位置到一个人类可读地址，是 被称为反向地理编码。
地理编码API支持直接使用经纬度反向地理编码 参数。例如，下面的查询包含 在布鲁克林的位置的纬度/经度值：
<$p$p><$c$c>http://maps.googleapis.com/maps/api/geo$c$c/json?latlng=40.714224,-73.961452&sensor=true_or_false
本文档介绍了如何跨preT JSON的结果，但StackOverflow上有不同的答案，解决更有效的方法来分析数据。

I have used Google geo address and using lat/long have got the address. How do I determine if I am on road on not? Basically hit-test for road? I am currently using location manager for lat/long and the GeoAddress is same for on road and next to road.
Final Solution
Use reverse geocoding via the Google Geocoding API.
The term geocoding generally refers to translating a human-readable address into a location on a map. The process of doing the converse, translating a location on the map into a human-readable address, is known as reverse geocoding.
The Geocoding API supports reverse geocoding directly using the latlng parameter. For example, the following query contains the latitude/longitude value for a location in Brooklyn:
http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true_or_false
The docs explain how to interpret the json results but StackOverflow has various answers addressing more efficient ways to parse the data.

Possible Solutions
Getting the nearest street/road coordinates in android - the answer to this question may point you in the right direction.
You can use directions api directly: http://maps.googleapis.com/maps/api/directions/json?origin=51,19&destination=51,19&sensor=false
Could you use the API to find directions which would then provide the closest road?
