Start edge was not found
I am getting this message when i get this command,
SELECT * FROM shortest_path_shooting_star('SELECT id, source, target, cost,reverse_cost, "x1", "y1", "x2", "y2", rule, to_cost FROM routing',603758,470694,true,true)
When i do a SELECT * FROM routing where id=603758 or id=470694, i get a valid record back.
Am i missing something fundamental? Problem with costs?
thanks

"Start edge was not found" probably means that the start edge was not found. ;-)
What is your ID? A vertex ID or an edge ID?
For Dijkstra and A* algorithm you need vertex ID's as start and end point because the algorithm routes from vertex to vertex. For Shooting* algorithm you need edge ID's as start and end, because the graph only cares about links.daniel05/15/09 07:37:24 (18 months ago)
