The Caml Hump: ocaml-osm-route

A quite simple program to do some basic routing over Open Streat Map maps. It parses an .osm.bz2 file, creates a compact data structure in memory (which is saved into a cache to speed up next searches), finds the OSM nodes closest to the source and goal points given as (latitude, longitude) couples, does the routing itself, prints it on the screen and saves it in .osm XML format (for example to load it into JOSM).
