Fast and flexible C++ library for working with OpenStreetMap data

The Osmium Library has extensive support for all types of OSM entities nodes, ways, relations, and changesets. It allows reading from and writing to OSM files in XML and PBF formats, including change files and full history files. Osmium can store OSM data in memory and on disk in various formats and using various indexes. Its easy to use handler interface allows you to quickly write data filtering and conversion functions. Osmium can create WKT, WKB, OGR, GEOS and GeoJSON geometries for easy conversion into many GIS formats and it can assemble multipolygons from ways and relations.
