Osmium is a c++ framework for working with osm data files. osmium can read osm data in xml or binary format (pbf) and can call different handlers for each osm object.

available handlers include:
* javascript handler (calls javascript callbacks you provide)
* multipolygon handler (assembles areas(multipolygons) from relations and
ways)
* nodelocationstore handler (stores node locations and builds way
geometries from them)
* statistics handler (does some general statistics)
* (others...)
this package provides the header files useful to develop third-party applications.
