1) to keep r.stream.basins as an add-on, demanding the delineation of<br>
multiple subbasins from coordinates to a user´s script looping<br>
r.water.outlet;<br>
2) to include r.stream.basins and keep also r.water.outlet;<br>
3) to include r.stream.basins in the core and remove r.water.outlet as<br>
obsolete.<br>
4) ?<br>
<br>

If r.stream.basins can replicate the functionality of r.water.outlet, I<br>
would prefer 3 . Some argument might be made for a conservative<br>
approach for option 2 for version 7.0 and drop r.water.outlet in version<br>
7.1, but 7.0 is in development status. Why not make the change now?<br>

As long as results are identical, +1. If not, this should be explored further.<span class=""><font color="#888888"><br>
