geopy地理查询库使用详解

geopy简介

可以使用geopy库来查询地址，国家，城市，地标，geopy使用的是第三方的geo解析器(包括谷歌地图，必应地图，Nominatim等)和一些数据源来获取地理信息

Each geolocation service you might use, such as Google Maps, Bing Maps, or Yahoo BOSS, has its own class in geopy.geocoders abstracting the service’s API. Geocoders each define at least ageocode method, for resolving a location from a string, and may define a reverse method, which resolves a pair of coordinates to an address.

geopy使用

从地址字符串获取Location对象

>>> from geopy.geocoders import Nominatim
>>> geolocator = Nominatim()
>>> location = geolocator.geocode("175 5th Avenue NYC")
>>> print(location.address)
Flatiron Building, 175, 5th Avenue, Flatiron, New York, NYC, New York, ...
>>> print((location.latitude, location.longitude))
(40.7410861, -73.9896297241625)
>>> print(location.raw)
{'place_id': '9167009604', 'type': 'attraction', ...}

从经纬度获取Location对象

>>> from geopy.geocoders import Nominatim
>>> geolocator = Nominatim()
>>> location = geolocator.reverse("52.509669, 13.376294")
>>> print(location.address)
Potsdamer Platz, Mitte, Berlin, 10117, Deutschland, European Union
>>> print((location.latitude, location.longitude))
(52.5094982, 13.3765983)
>>> print(location.raw)
{'place_id': '654513', 'osm_type': 'node', ...}

计算两点间距离

可以使用 Vincenty distance 或 great-circle distance

>>> from geopy.distance import vincenty
>>> newport_ri = (41.49008, -71.312796)
>>> cleveland_oh = (41.499498, -81.695391)
>>> print(vincenty(newport_ri, cleveland_oh).miles)
538.3904451566326

>>> from geopy.distance import great_circle
>>> newport_ri = (41.49008, -71.312796)
>>> cleveland_oh = (41.499498, -81.695391)
>>> print(great_circle(newport_ri, cleveland_oh).miles)
537.1485284062816
