I have set up Postgresql, PostGIS and pgrouting on Ubuntu. I have imported an osm for wales using the following command:
./osm2pgrouting -file wales.osm \ -conf mapconfig.xml \ -dbname routing \ -user postgres \ -clean
All I now want to do is execute something to give me the fastest route between 2 Latitude/Longitude points.
Start: 51.499954,-3.571651 End: 53.386809,-4.445
The route has to be in the format of a series of latitude/longitude positions that make up the route.
Is this even possible? If not, what would it take to make it possible.
If it is possible, what sql do I need to execute?
I have been looking everywhere for an answer to no avail.
Further to Steve Horn's recommendation. I have now managed to get 5000 points coming back using this sql:
SELECT gid, AsText(the_geom) AS the_geom FROM dijkstra_sp('ways', 15522, 26857);
However, the points all seem to be ignoring the road type. (When I run it using Google Directions, the route mainly follows the main roads). What have I done wrong?
