I'm using QGIS. I'm new.
I have a CSV file, with the source point (the_geom) and destination point (the_geom).
I have a road network already imported into PostGIS with pgRouting, and I need to have the ability to calculate the distance from a source to a destination, by using the road path as the road. After calculating, it should save the distance back into the DB in a new column.
Is there any quick and easy way to solve this?
Thanks for all the help! :)
