I am using pgr_dijkstra for finding the shortest path between two given nodes. The network map is actually a grid based one and I have created all the necessary columns and working fine. But I do not understand how does the id2 (which is edge) given?
The values given for id2 (e.g., 59721224, 59721496 ...) can not be found any of my tables. So how does this id2 (edge) values are given? Every single time I query pgr_dijkstra, id2 values are changing but none of the other columns are changing.
This is how my wp_norway_network1 table looks:
