Hi Markus, What I'm trying to do is start with a raster stream map from r.drain and convert it to a sequence of vector points, where each point has information as to its position along the stream. I then use the points for sampling a stream profile and related information. Oddly enough, with

Hello Michael You could use r.stream.order after r.stream.extract to get your stream network ordered, and then, after running r.thin on the ordered stream network, convert it to vector using r.to.vect with the -v flag, that way, each order is a cat, you can them use v.to.points or the add-on

r.stream.extract can make the raster streams—ones that are pretty much equivalent to those made with r.watershed. But it can’t do stream profiles AFAICT. Also, like r.watershed, it extracts a stream network, not a particular stream. That is why we’re using r.drain to extract a particular

Hi, I receive the following error on importing an ESRI binary grid file into GRASS 7. I guess that the error can be ignored as the imported file type is float32 so there is no .vat file? I'm not sure if related to GRASS or GDAL? Cheers, Richard -- View this message in context:
