The Walking time is a QGIS python plugin that uses Tobbler’s hiking function to estimate the travel time along a line depending on the slope. The input data required are a vector layer with lines and a raster layer with elevation values. One can adjust the base velocity (on flat terrain) according to the type of walking or walker.
