OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. The initial map data was originally collected by volunteers performing systematic ground surveys using a GPS unit and other devices.
The OSM geospatial data are stored and processed in different formats. Two main formats are:
- OSM XML – xml-format provided by the API
- PBF – highly compressed, optimized binary format that uses Google's Protocol Buffers.
This section describes configuration parameters used in OSM data source provider.
