[pgrouting-users] routing in linestring trouble

[Stephen Woodbridge]

Andrea,

You have to use "noded" data. All linstrings must be broken at 
intersections, like:

BAD                 GOOD

A                   A
|                   |
|                   |
|B----------D       B----------D
|                   |
|                   |
C                   C


A->C, B->D          A->B, B->C, B->D
