I'm working on a project that I have to model a highway map into a network and apply some network analysis algorithms in that network to get insight into.
I found that QGIS Road Graph Plugin routing pretty well only with raw map data. So I searched for source code of this plugin but it seem that the SVN repository hasn't available any more. I searched in QGIS Github repository, but still cannot find.
Do you have any idea about where they put that code in?
