Hi List!
I officially announce new modules for hydrological analysis:
r.stream.order - for strahler, horton etc. stream order analysis
r.stream.basins - for delineate basins according different stream file (more advanced than r.water.outlet)
r.stream.distance - for calculating distance to and elevations above streams and outlets
r.stream.stats - for calculate hortonian statistics
Modules work both on planimetric and LL locations. Thier only limitation is lack of support of massive grids. But for computers with 2GB RAM
there should be no problems with datasets up to 10M cells
More information and tutorial on http://heretic.livenet.pl/heretic
I think that modules meets all requirements from rfc2 so please add them to grass addons database.
I tested modules before submit but if someone find some errors or bugs please let me know.
best regards
Jarek Jasiewicz
