I 145013 Danish addresses, and 10 big cities in Denmark as points in
QGIS. Furthermore, I have four vector layers that connect all the points. They are small roads, main roads, freeways and ferry routes. See the screen dump from
QGIS below for an illustration:
Now I would like to calculate the shortest distance from each address to each of the 10 big cities. I will use
pgRouting for this, and I have followed the nice tutorial on finding 1 shortest path here http://anitagraser.com/2013/07/06/pgrouting-2-0-for-windows-quick-guide/
However, I can't figure out how to extend the problem from 1 path to (145013 * 10 =) 1450130 paths.
- What method should I use in
pgRouting, and how do I incorporate all the 1450130 paths?
- QGIS 2.1.0
- postgres 9.2
- postgis 2.0
- pgRouting 2.0
- OS: Win 7 64bit
I have shared my data here: https://www.dropbox.com/sh/rn8gdxr1bki4q4x/fFRd0PerkP
It's in in a QGIS project file.
I appreciate all comments and answers!
