Hi, i build a topology using pgrouting`s function assign_vertex_id('vias', 0.1, 'the_geom', 'gid'); after that i found one vertex that constains the follow structure as you see, the node_id code don`t appears in the column target_id.
the question is, is bad the graph? this is the query from edges and node tables "node_id";"name_street";"source_id";"target_id" 165;"AV0400000C070";165;151 165;"CL0900000C050";165;166 165;"CL0900000C060";165;164 165;"AV0400000C060";165;174 this is the aproximate graphical representation, the vertices of the graph are connected to other edges, for simplify i put only the graph shown in the table | | | ---------------------*----------------------- | | | * is the node which converge the edges. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
