geopy is a Python 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

OpenStreetMap Nominatim
,
Google Geocoding API (V3)
, and many other geocoding services. The full list is available on the
Geocoders doc section
. Geocoder classes are located in
geopy.geocoders
.

geopy is tested against CPython (versions 3.5, 3.6, 3.7, 3.8, 3.9) and PyPy3. geopy 1.x line also supported CPython 2.7, 3.4 and PyPy2.

Geocoding

To geolocate a query to an address and coordinates:

.. code:: pycon

>>> from geopy.geocoders import Nominatim
>>> geolocator = Nominatim(user_agent="specify_your_app_name_here")
>>> 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', ...}

To find the address corresponding to a set of coordinates:

.. code:: pycon

>>> from geopy.geocoders import Nominatim
>>> geolocator = Nominatim(user_agent="specify_your_app_name_here")
>>> 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', ...}

Measuring Distance

Geopy can calculate geodesic distance between two points using the

geodesic distance
_ or the
great-circle distance
_, with a default of the geodesic distance available as the function
geopy.distance.distance
.

Here's an example usage of the geodesic distance, taking pair of :code:

(lat, lon)
tuples:

.. code:: pycon

>>> from geopy.distance import geodesic
>>> newport_ri = (41.49008, -71.312796)
>>> cleveland_oh = (41.499498, -81.695391)
>>> print(geodesic(newport_ri, cleveland_oh).miles)
538.390445368

Using great-circle distance, also taking pair of :code:

(lat, lon)
tuples:

.. code:: pycon

>>> 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)
536.997990696
