This post covers the necessary steps to use osm2po on Windows. Osm2po is both, a converter and a routing engine. It parses OpenStreetMap data and makes it routable. While osm2pgrouting seems to be limited by the amount of memory that is available on your system, osm2po is able to convert large sets like europe.osm. It generates SQL Insert scripts for PostGIS, compatible with pgRouting and Quantum GIS.
That’s all, you’re ready!
To load your network from the .pbf run:
C:\Users\Anita\temp\osm2po-4.2.30>java -jar osm2po-core-4.2.30-signed.jar prefix=at "C:\Users\Anita\Geodaten\OpenStreetMap Data\austria.osm.pbf"
Once finished, you should be able to test the results by visiting http://localhost:8888/Osm2poService in your browser:
