Calculating distance to stream for multiple TFAs with RouteDEM
I ran RouteDEM with multiple stream thresholds, and I wanted to compare how the distance to stream for different points changed as I changed the TFA. I used TFA of 1400, upper limit 1800, stepsize 200, and checked "calculate distance to stream". This should theoretically have given me three different v_stream outputs, and three different downstream_distance outputs as well (or so I thought). But, although I did get three v_streams, I still only got one downstream_distance.tif. Is this calculated for the first TFA (1400)? or the last (1800)? Or am I missing some output somewhere? It would be great to have the stream distance rasters for each TFA - is that possible? Obviously I could run the tool manually over a range of TFAs and specify a different downstream distance filename each time, but wondering if that is automate-able.
