Issues while plotting the results of pgRouting shortest path
I am trying to actually figure out what this column exactly represents and how to use that in my case. I created a network topology and persisted it to postgresql database using
osm2po tool for a certain region. Now I am using pgrouting on it to find the shortest route. I am not sure how this column is used by qgis to display the route. It's just a bunch of number, how can I use it in my case?
I am actually using gpx format file to transfer the shortest path. How can I exploit this geometry and send that information in gpx so that it is displayed nicely.
