Thank Johannes!!!
right! I make some test and yes if you provide the flow=temp the output
accumulation will be the accumulation of the temp weighted by the area of
each cell.
So if i divide temp_accumulation / flowaccumulation i get the upper-stream
mean temperature.
Thank you very much
Hi:
There's an option to the r.univar module that takes a "zones"
raster, and calculates univariate statistics for each zone.
Statistics like mean, max, count, etc are calculated from the input
raster for each category in the zones file. The zones, in your case
would
Hi,
I'm searching for a GRASS command that is able to "accumulate" a raster
following the flow accumulation output obtained by r.watershed.
In other words if I have a temperature raster I would like to
accumulate the temperature values following the drainage direction. The
final results would to
