Python Geocoder

Simple and consistent geocoding library written in Python.

Many online providers such as Google & Bing have geocoding services, these providers do not include Python libraries and have different JSON responses between each other.

It can be very difficult sometimes to parse a particular geocoding provider since each one of them have their own JSON schema.

Here is a typical example of retrieving a Lat & Lng from Google using Python, things shouldn't be this hard.

>>> import requests
>>> url = 'https://maps.googleapis.com/maps/api/geocode/json'
>>> params = {'sensor': 'false', 'address': 'Mountain View, CA'}
>>> r = requests.get(url, params=params)
>>> results = r.json()['results']
>>> location = results[0]['geometry']['location']
>>> location['lat'], location['lng']
(37.3860517, -122.0838511)

Now lets use Geocoder to do the same task.

>>> import geocoder
>>> g = geocoder.google('Mountain View, CA')
>>> g.latlng
(37.3860517, -122.0838511)

API Overview

Many properties are available once the geocoder object is created.

Forward

>>> import geocoder
>>> g = geocoder.google('Mountain View, CA')
>>> g.geojson
>>> g.json
>>> g.wkt
>>> g.osm

Reverse

>>> g = geocoder.google([45.15, -75.14], method='reverse')
>>> g.city
>>> g.state
>>> g.state_long
>>> g.country
>>> g.country_long

House Addresses

>>> g = geocoder.google("453 Booth Street, Ottawa ON")
>>> g.housenumber
>>> g.postal
>>> g.street
>>> g.street_long

IP Addresses

>>> g = geocoder.ip('199.7.157.0')
>>> g = geocoder.ip('me')
>>> g.latlng
>>> g.city

Bounding Box

Accessing the JSON & GeoJSON attributes will be different

>>> g = geocoder.google("Ottawa")
>>> g.bbox
{"northeast": [45.53453, -75.2465979], "southwest": [44.962733, -76.3539158]}

>>> g.geojson['bbox']
[-76.3539158, 44.962733, -75.2465979, 45.53453]

>>> g.southwest
[44.962733, -76.3539158]
