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 contains the Javascript framework based on osmium.
