in QGIS 3.2, I'm trying to apply "Shortest Path (Layer to Point)" from
the Processing Toolbox. The algorithm generates a layer with a feature
"cost", but I cannot find a way to interpret this feature nor a way how
to modify what it contains. Seemingly by chance it once contained a
distance in km and the other time some real number that I cannot interpret.
Does someone know how to specify the desired output of shortest path
analysis (km and minutes of traveling in my case)?
I'm very new to QGIS so I am only using the GUI so far.
