geopy使用详解　　由于专业需要，经常接触一些地理处理的工具包，文档都是英文的，自己看的同时将其翻译一下，一方面自己学习的同时有个记录，要是能同时给一起的学习的童鞋们一些帮助，想想也是极好的。以下的文档内容主要翻译自官方文档，水平有限，错误的地方希望大家指出。　　处理地理数据经常会涉及到地理编码的问题。地理编码指的是将地理信息转化成坐标关系的过程。分为正向和反向的编码。正向的是指将地址信息转换为坐标点，比如：武汉市武汉大学-->(114.3594147, 30.5401222) ；反向地理编码就是将地理坐标转换为具体的地址，是一个与前面相反的过程。　　基于python的地理编码库geopy 是用于地理编码的常用工具，使用它可获取多种地图服务的坐标。目前Python2和Python3下都支持。Python开发者可以使用geopy很容易的获取全球的某个街道地址，城市，国家和地块的地理坐标，它是通过第三方的地理编码器和数据源来解析的。 geopy可以使用的地理定位服务如下： OpenStreetMapNominatim , ESRIArcGIS , GoogleGeocodingAPI(V3) , BaiduMaps , BingMapsAPI , Yahoo!PlaceFinder , Yandex , IGNFrance , GeoNames , NaviData
