I'm trying to get all the routes from a source point (i.e. 336) to a group
of target/destination points (located at different edges/ends of
linestrings' network) using the below code:
SELECT seq, id1 as path, id2 as node, id3 as edge, (b.geom) as geom, cost
'SELECT id, source, target, (st_length(geom) * 0.001) as cost FROM
336, (SELECT array_agg(id) FROM schema.l1_pv1), false, false
) a, schema.network_noded b
It's resulting a weird de-attached "little" pieces of my original
nodded_network! However, the number of resulted paths is equal to the
target/destination points. Please advise:
1) What potential mistake I may have committed?
2) Does it mean that all the calculated travel_cost(s) are wrong (as
they are reflected/represented by wrong linestrings)?
I'm using QGIS 2.4.0 and pgRouting pg93-binaries-2.4.0
I found similar question on this list of pgRouting users, asked by Antonio
), but obviously the question is not answered yet?
