[postgis-users] PostGIS 2.0 Wishlist - PgRouting 1.0.0.a

[Anton A. Patrushev]

Hi David,

Yeah, I know. Thank you for your tutorial! :)

Well, I wrote few words in README.routing file...
But I guess it is not so helpfull :)

So, it works almost like A* with several differences:
1. It calculates a path from edge to edge (not from vertex to vertex)
2. You need 2 more columns - rule (varchar) and to_cost (double precision).

For example,

 gid | source | target | cost | x1 | y1 | x2 | y2 | to_id | to_cost | rule
-----+--------+--------+------+----+----+----+----+-------+---------+------
  12 |      3 |     10 |    2 |  4 |  3 |  4 |  5 |       |    1000 | 14

means that cost of going from edge 14 to edge 12 is 1000,

and

 gid | source | target | cost | x1 | y1 | x2 | y2 | to_id | to_cost | rule
-----+--------+--------+------+----+----+----+----+-------+---------+------
  12 |      3 |     10 |    2 |  4 |  3 |  4 |  5 |       |    1000 | 14, 4

means that cost of going from edge 14 to edge 12 through edge 4 is 1000.

Indeed, I should write better readme :)

Anton.
