Hi list!
I announce major update of r.stream.*:
new nodule r.stream.angle: to calculate stream direction and
inter-stream relation. That module use experimental algorithm to divide
streams int shorter but near-straight line segments, and next calculate
its direction (0-360 downstream). It may also divide line into segments
along ordered lines of the same Strahler, Horton or Main stream order,
depending on user choice. More in the description.
I didn't know any GIS software which do such or similar segmentation. If
someone knows (open or proprietary) I will be grateful for pointing it.
major update r.stream.distance: now it can calculate distance to
streams/junction/outlet downstream (default, it was previously available
as thje whole module) and new option to calculate distance to the local
or farthest maximum/divides upstream. See more details in the description.
regards
Jarek Jasiewicz
Any plans to move this to the main SVN? It seems like a very good addition to the GRASS tool set.

Hi Michael!
Good idea (from my point of view). If yes, I need little time to finally polish the code, add some additional functionality and port it to GRASS 7. So if there will be such decision (to move it to main SVN) I need a month to finish all I planned (I do not want access to main SVN branch yet).
