The pygeoif module is a pure Python module that implements a protocol known as the geo_interface.

This protocol allows Python object-level introspection of geospatial data, for example, it converts geospatial data formats into Python objects. It will be used to convert between shapefile geometries stored in binary into WKT geometries that can be inserted into the database using the GeoAlchemy2 ORM:
