Thread: pgr_createTopology creates bad topology
Hi, I want to calculate the shortest way between two points using pgr_dijkstra function. When I excecute that function, it doesn't show anything. Only when two points are just in front of each other, pgr_dijkstra shows the way it is between them. Just in this last case, pgr_dijkstra works fine. But when the calculation is more complex, pgr_dijkstra does nothing. I made a lot of tries and I am sure that pgr_createTopology doesn't work as it should. Maybe my table needs more fields to get its topology done well, but I don´t know what. An explanation about what fields are needed for pgr_createTopology would be helpful too. I attach two screenshots: how it built the table's topology and its fields composition. Thank you very much! <http://postgresql.nabble.com/file/n5925750/forum.jpg> <http://postgresql.nabble.com/file/n5925750/forum_2.jpg> -- View this message in context: http://postgresql.nabble.com/pgr-createTopology-creates-bad-topology-tp5925750.html Sent from the PostgreSQL - pgadmin support mailing list archive at Nabble.com.
