I am calculating the path distance in ArcMap 10.1,
My inputs are point locations(source) from which I am calculating the path distance. A cost raster that shows the impedance per cell(30m) and impedance in terms of minutes taken to cross each cell.
A DEM defining the elevation values at each cell location that is the surface raster and the same DEM to apply for slope correction ToblerAway When I run the function without the DEM for slope correction I get realistic time of 0-80 minutes.
When I incorporate the DEM and use the ToblerAway within the path distance, my results become unrealistic and get 0- 0.36 minutes. The DEM is SRTM 30 m projected in UTM. What could be the problem?
