I have calculated shortest route/path by using pg_Dijkstra algorithm in PostGIS and it is working fine. Now how to calculate driving directions from starting edge to end edge. I have gone through the link. But unable to go forward.

Is there any algorithm or procedure to calculate driving directions in PostGIS?

  • what is the difference between the shortest route and driving directions? – Ian Turton Jul 17 at 13:08

    with driving directions the shortest route is "translated" into natural language and passed as directions to the driver (ie. turn left, go straight, etc) – vagvaf Jul 17 at 13:12
