THIS IS THE "OLD" OSMIUM WHICH IS NOT BEING DEVELOPED ANY MORE!You almost certainly want the "new" Osmium at http://osmcode.org/

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:
Of course, you can also write your own handlers.
There are a few applications that use Osmium in the examples directory.
The osmjs directory contains the osmjs application that calls your Javascript code which can then work with the OSM data. It can, for instance, be used to convert OSM data into Shapefiles.
Note that OSM input files must contain objects in the right order for Osmium to work properly: first nodes, then ways, then relations. Normally OSM files are sorted this way, but if yours aren't, you can use Osmosis with the --sort option to do this.
Different parts of Osmium (and the applications built on top of it) need different libraries:
boost (several libraries) http://www.boost.org/ Debian/Ubuntu: libboost-dev openSUSE: boost-devel
zlib (for PBF support) http://www.zlib.net/ Debian/Ubuntu: zlib1g-dev openSUSE: zlib-devel
shapelib (for shapefile support in osmjs) http://shapelib.maptools.org/ Debian/Ubuntu: libshp-dev openSUSE: libshp-devel
libgd (for nodedensity example only) http://www.libgd.org/ Debian/Ubuntu: libgd2-xpm-dev openSUSE: gd-devel
GDAL (for OGR support) http://gdal.org/ Debian/Ubuntu: libgdal1-dev openSUSE: libgdal-devel
Expat (for parsing XML files) http://expat.sourceforge.net/ Debian/Ubuntu: libexpat1-dev openSUSE: libexpat-devel
GEOS (for assembling multipolygons etc.) http://trac.osgeo.org/geos/ Debian/Ubuntu: libgeos++-dev openSUSE: libgeos-devel
Google sparsehash http://code.google.com/p/google-sparsehash/ Debian/Ubuntu: libsparsehash-dev openSUSE: sparsehash
Google V8 Javascript engine (for Javascript support) http://code.google.com/apis/v8/ Osmium works with V8 version 3.14 and 3.15, but not with 3.21. Debian/Ubuntu: libv8-dev openSUSE: v8-devel
LibICU (for UTF-8/UTF-16 conversion, only for Javascript support) http://site.icu-project.org/ Debian/Ubuntu: libicu-dev openSUSE: libicu-devel
Google protocol buffers (for PBF support) http://code.google.com/p/protobuf/ (at least version 2.3.0 needed) Debian/Ubuntu: libprotobuf-dev protobuf-compiler openSUSE: protobuf-devel Also see http://wiki.openstreetmap.org/wiki/PBF_Format
Doxygen (to build API documentation) http://www.stack.nl/~dimitri/doxygen/ Debian/Ubuntu: doxygen
libboost-test (for tests) http://www.boost.org/doc/libs/1_47_0/libs/test/doc/html/index.html Debian/Ubuntu: libboost-test-dev
OSMPBF (for PBF support) https://github.com/scrosby/OSM-binary Debian/Ubuntu: libosmpbf-dev
You need to either install the packages for your distribution or install those libraries from source. Most libraries should be available in all distributions.
Doxyfile - Needed for building the Osmium C++ docs, call "make doc" to build. include - C/C++ include files. All of Osmium is in those header files which are needed for building Osmium applications. osmjs - Osmium application "osmjs". osmjs/js - Example Javascript handlers. examples - Osmium example applications. test - Tests (see below). debian - Needed to build Debian/Ubuntu packages.
First you need to (build and) install all the prerequisites.
Osmium is a header-only library, so there is nothing to build for the library itself.
Call "make doc" in the top-level directory to build the Osmium C++ docs.
Call "make install" to install the include files and documentation.
See "examples/README" for build instructions of the example applications.
See "osmjs/README" for build instructions of osmjs.
Call "make clean" in any of those places to clean up.
To use Osmium in your code you just have to include the headers you are interested in. So, if you need the Way class for instance you include <osmium/osm/way.hpp>. If you need the Debug handler, you include <osmium/handler/debug.hpp>.
If you need any OSM file input, then first define one or both of these macros
and then include
There are some parts of Osmium that are a bit more difficult to use. You'll find some examples in the 'example' and 'osmjs' directories.
There are a few tests using the Boost Unit Test Framework in the "test" directory. Many more tests are needed, any help appreciated.
Run "make test" from the main directory or go to the "test" directory and type "./run_tests.sh" to compile and run the tests. You can run a single test by calling "./run_test.sh TESTFILE", for instance: ./run_test.sh t/osm/test_node.cpp
There are some other tests that are not neatly integrated. Go to the "test" directory and run broken_way_geometries/test.sh or utf8_clipping/test.sh
Osmium is available under the GNU LGPL version 3 or later, or - at your option - the GNU GPL version 3 or later.
See http://eigen.tuxfamily.org/index.php?title=Licensing_FAQ&oldid=1116 for a good description of what that means.
