I would like to estimate the walking time per cell in the Slope. I read that I should use "Reclassify" on the Slope raster to convert the values to cost in seconds to traverse a single cell. So, my question is: how could I convert the slope degrees in meters per second? I saw that, maybe, I could use the Tobler's hiking fuction, yet actually it is not more clear for me.
All of this because it's necessary in order to create a walking time buffer with barrier on the base of a DTM (I use ArcGIS 10.3.1)
Does someone have some suggestions?
Thank you in advance!
