GeoPandas is an open source project to add support for geographic data to pandas objects. It
currently implements `GeoSeries` and `GeoDataFrame` types which are subclasses of
`pandas.Series` and `pandas.DataFrame` respectively. GeoPandas objects can act on
`shapely` geometry objects and perform geometric operations.
GeoPandas is a community-led project written, used and supported by a wide range of
people from all around of world of a large variety of backgrounds. Want to get involved
in the community? See our [community guidelines](community).
GeoPandas will always be 100% open source software, free for all to use and released
under the liberal terms of the BSD-3-Clause license.
