Python Geocoding Toolbox

Project description

geopy is a Python 2 and 3 client for several popular geocoding web services.

geopy makes it easy for Python developers to locate the coordinates of addresses, cities, countries, and landmarks across the globe using third-party geocoders and other data sources.

geopy includes geocoder classes for the ESRI ArcGIS, OpenStreetMap Nominatim, Google Geocoding API (V3), Yahoo! BOSS,, and Bing Maps API geocoder services, as well as several other. The various geocoder classes are located in geopy.geocoders.

Using pip:

pip install geopy

Or, manually: download the tarball from PyPI, unzip, and execute this in the same directory:

python install


To geolocate a query to an address and coordinates:

>>> from geopy.geocoders import GoogleV3
>>> geolocator = GoogleV3()
>>> address, (latitude, longitude) = geolocator.geocode("175 5th Avenue NYC")
>>> print(address, latitude, longitude)
175 5th Avenue, New York, NY 10010, USA 40.7410262 -73.9897806

To find the address corresponding to a set of coordinates:

>>> from geopy.geocoders import GoogleV3
>>> geolocator = GoogleV3()
>>> address, (latitude, longitude) = geolocator.reverse("40.752067, -73.977578")
>>> print(address, latitude, longitude)
77 East 42nd Street, New York, NY 10017, USA 40.7520802 -73.9775683

Measuring Distance

Geopy can calculate geodesic distance between two points using the Vincenty distance or great-circle distance formulas, with a default of Vincenty available as the class geopy.distance.distance, and the computed distance available as attributes (e.g., miles, meters, etc.).

Here’s an example usage of Vincenty distance:

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

Using great-circle distance:

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

0.97 - December 26, 2013

CHANGED: SSL connections are used by default for services with support.
These geocoders accept a new ‘scheme’ argument in their init, which may be ‘https’ or ‘http’. Users desiring unencrypted connections must now specify ‘http’. Note that SSL connections’ certificates are not verified.
CHANGED: Geocoders accept a timeout argument which specifies the number of
seconds to wait before raising a GeocoderTimedOut exception. This can be specified in the init, or specified one-off in each geocode or reverse call. There is now a default of 1 second.
CHANGED: geopy now supports Python 2 and Python 3 on a single codebase.
Support for Python 2.5 is also dropped.

CHANGED: GoogleV3’s protocol argument is deprecated in favor of scheme.

ADDED: ESRI’s ArcGIS geocoder implemented. Contributed by Arsen Mamikonyan.

ADDED: Geocoders accept a proxies argument which specifies a proxy to
route its geocoder requests through. It uses urllib, and accepts proxies in the form of a dictionary of {scheme: proxy address}, e.g., {“https”: “”}. This was present but undocumented in 0.96.
ADDED: Geocoders check a new method, _geocoder_exception_handler, if
defined, when the HTTP call to the geocoder’s service raises an exception. See LiveStreets for an example. Users can define or override this method.

ADDED: LiveStreets throws a GeocoderQuotaExceeded exception when appropriate.

ADDED: Point can parse a greater variety of coordinate strings. Contributed
by nucflash.
FIXED: GeocodersDotUS now authenticates with an Authorization HTTP header.
Contributed by Arsen Mamikonyan.

REMOVED: MediaWiki and SemanticMediaWiki geocoders removed.

REMOVED: Geohash module has been removed.

Full changelog available at the repository.
