Hello!
I have a question regarding network plugins for qgis. I am trying to
solve a problem regarding gravel trucks and slope, with the idea of
saving money on fuel, as a fully loaded gravel truck uses more gas to go
up a slope, rather than down. I have managed to get the slope data I
needed, and draped it over the road lines, giving me a start and end
slope, with a third column for the average of the start and end slope
degrees. The problem is this: I can't find a network analysis plugin for
qgis of any kind that allows for user defined impedences, allowing me to
create a road hierarchy. I know that ArcGIS has that functionality, but
I was hoping that QGIS would have something like that, and I am not sure
if I can build it.
You can use the GRASS GIS v.net.* modules which are accessible via the
processing framework's toolbox if GRASS GIS is installed. They allow
defining a cost column for impedences.
