"用于从美国城市名称中获取纬度和经度的 Python 模块"

Question

我正在寻找一个python模块，它可以将城市名称作为输入并返回输入的纬度和经度。

Answer 1

Have a look at geopy . In the "getting started" documentation it shows:

>>> from geopy import geocoders  
>>> gn = geocoders.GeoNames()

>>> print gn.geocode("Cleveland, OH 44106")
(u'Cleveland, OH, US', (41.4994954, -81.6954088))

>>> gn.geocode("Cleveland, OH", exactly_one=False)[0]
(u'Cleveland, OH, US', (41.4994954, -81.6954088))

Answer 2

An example:

from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent='myapplication')
location = geolocator.geocode("Chicago Illinois")
print(location.address)

Available info:

>>> location.raw
{u'display_name': u'Chicago, Cook County, Illinois, United States of America', u
'importance': 1.0026476104889, u'place_id': u'97957568', u'lon': u'-87.6243706',

You can also use geocoder with Bing Maps API. The API gets latitude and longitude data for all addresses for me (unlike Nominatim) and it has a pretty good free version for non-commercial uses (max 125000 requests per year for free). To get free API, go here<\/a> and click "Get a free Basic key". After getting your API, you can use it in the code below:

import geocoder # pip install geocoder
g = geocoder.bing('Tokyo', key='<API KEY>')
results = g.json
print(results['lat'], results['lng'])
