I just finish first version of new grass module r.stream. Module is regular Grass module, written in C an has no addational dependencies. It was compiled with GRASS65 devel downloaded in last two week. Source code you can find here: http://heretic.livenet.pl/heretic/r.stream.tar.gz Module compiles and seems to work. Analysis was tested only on one dataset. To compile it copy r.streams directory to your grassXX../raster/ cd

I just finish first version of new grass module r.stream. Module is regular Grass module, written in C an has no addational dependencies.

Analysis of r.stream shall be run on same regions setings as r.watershed. If no, run g.region rast=your_dir_file first. For now module do not check if region and rasters are identical. It is planned to add in nearest feature. It also do not check if dirs and streams are SDF result. Threre are no addational description. It will be added after testing. It works only on cells data. Floating points data are not allowed (and have no sense). Module is quite fast. 3000 x3000 cells all three analysis runs no more than 30 s. on AMD 3800 2GB, Ubuntu 8.04 Module is part of comprehensive project which will add full Horton analysis and some addational terrrains analysis to Grass. More details in the feature. Any cooperation is
Re: [GRASS-user] Re: announcement of strahler stream order analysis
It works fine on my machine. Mac OS X, compilied addon and compilied GRASS from scratch. The strahler output also looks sensable. I do have a question, though. Say I have my own delineated streams with another method, but in raster format- will this still work? And is there an easy way to a vector out of a raster stream network?

I just finish first version of new grass module r.stream. Module is regular Grass module, written in C an has no addational dependencies. It was compiled with GRASS65 devel downloaded in last two week. Source code you can find here: http://heretic.livenet.pl/heretic/r.stream.tar.gz Module compiles and seems to work. Analysis was tested only on one
