jrouteosm (which does the precalculation) uses great circle distances. So does the current version of the ruby code. I tried using plain cartesian distances in the ruby code - this made no visible speed difference. You could doubtless speed up the precalculation by having jrouteosm use cartesian distances, but my concentration was on having the "live" phase be as fast as possible. -- Jon _______________________________________________ Routing mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/routing
