GeosPy: Geolocation Inference Made Easy

=======================================

.. image:: https://travis-ci.org/tylfin/GeosPy.svg?branch=master

    :target: https://travis-ci.org/tylfin/GeosPy

GeosPy is a MIT Licensed Geolocation Inference Library, written in Python.

Of the few existing Python modules for conducting geolocation inference,

most are verbose and cumbersome.

.. code-block:: python

    >>> from GeosPy import Geos

    >>> geosPy = Geos()

    >>> print(geosPy.models)

    frozenset({'jakartr', 'backstrom'})

    >>> geosPy = geosPy.set_model('backstrom')

    >>> user_location_dict = {

    ... 'Tyler': (44, -71.5), 'Tim': (45.5, -73.5), 'Gwyn': (44.5, -89.5), 

    ... 'Conor':(55.0, -106.0), 'Sam': (25.7, -80.2), 'OffTheGrid': None}

    >>> user_friend_dict = {'OffTheGrid': ['Tyler', 'Sam', 'Gwyn', 'Conor', 'Tim']}

    >>> print(geosPy.locate(user_location_dict, user_friend_dict))

    {'Conor': (55.0, -106.0), 'Sam': (25.7, -80.2), 'Tyler': (44, -71.5), 

    'Gwyn': (44.5, -89.5), 'Tim': (45.5, -73.5), 'OffTheGrid': (45.5, -73.5)}

    ...

GeosPy is based off of `Jurgens et al. (2015)`_, implementing state-of-the-art

methods for geolocation inference. It allows the user to locate nodes with unknown locations

based solely on network-based relationships.

*Geolocation inference* is the identification of the real-world geographic location of an object on Earth based off of available data. GeosPy currently only supports network based inference methods.

Features

--------

- State-of-the-art geolocation inference method(s)
