PyDriosm: an open-source tool for downloading, reading and PostgreSQL-based I/O of OpenStreetMap data

PyDriosm is an open-source tool for researchers/practitioners to easily download and read OpenStreetMap (OSM) data in popular file formats such as protobuf binary format (PBF) and shapefile, which are available for free download from Geofabrik and BBBike. The package also provides a convenient way for PostgreSQL-based I/O and storage of parsed OSM data.
