[GRASS-dev] r.stream.watersheds & r.stream.variables add-on

[Giuseppe Amatulli]

Hi,
we have developed 2 grass add-on

"r.stream.watersheds" that performs (for each single grid cell of a stream
network) the sub-watershed delineation based on the drainage direction and
a gridded stream network


"r.stream.variables" which will calculate and relate the
upstream-contributing environmental conditions (contiguous layers, e.g.
air-temperature, elevation, land use, etc.) to each stream grid cell.
https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.stream.variables

The main output is thus an environmental variable that follows the river
continuum from the source to the mouth of a river, and can be used in e.g.
species distribution models (or any ecological model).

A publication has been submitted and will be soon on line.

Right now the add-on is in Bash ( it was easier to adapt the same script
that we use in the high-performace-computing for the massive computation)
but we are planing to translate in  python.

While converting the add-ons into python, we want to provide users the
possibility to use these tools. We would like to fill in the manual
page, and provide a short-term work-around (copy the .sh-files into
/scripts, as this works perfectly).

Meanwhile, we work on the python version and release it as soon as
possible. Does this sound reasonable?

Is there a way we could have the manual page for these add-ons online?

Thanks and best wishes,
Giuseppe & Sami
