[GRASS-dev] r.watershed and swap memory

[Luca Casagrande]

Hello everybody.
While Ivan is working on r.watershed I am trying to reach the result using
TerraSTREAM.

With the help of Thomas, I have successfully created a drainage map from the
DEM and the idea is to use it
with r.water.outlet. The problem is that it needs a drainage map with values
that run from -8 to 8, instead TerraSTREAM prompt out a bitmap (using SFD)
or a raster with values from 0 to 360 degree (with MFD). I can reclass it
with r.reclass
but I don't know how handle negative values.

Any suggestion on this?

Thanks

Luca
