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

    Warning

    The 1.x series will not receive any new features or bugfixes
    unless explicitly asked on the issue tracker.

    Consider upgrading to geopy 2.

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`_.

.. _OpenStreetMap Nominatim: https://nominatim.org
.. _Google Geocoding API (V3): https://developers.google.com/maps/documentation/geocoding/
.. _Geocoders doc section: https://geopy.readthedocs.io/en/latest/#geocoders
.. _geopy.geocoders: https://github.com/geopy/geopy/tree/master/geopy/geocoders

geopy is tested against CPython (versions 2.7, 3.4, 3.5, 3.6, 3.7, 3.8),
PyPy, and PyPy3. geopy does not and will not support CPython 2.6.

Installation
------------

Install using `pip <http://www.pip-installer.org/en/latest/>`__ with:

::

    pip install geopy

Or, `download a wheel or source archive from
PyPI <https://pypi.python.org/pypi/geopy>`__.

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
<https://en.wikipedia.org/wiki/Geodesics_on_an_ellipsoid>`_ or the
`great-circle distance
<https://en.wikipedia.org/wiki/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:

.. 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:

.. 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
