Re: [GRASS-user] Error exporting to tiff
Hi, I resolve the error. The original raster to convert was in 16bit value, and before to do the r.gdal.out is need to rescale to 8 bit. I wrongly uess the setting BYTE in r.gdal.out was to convert from 16bitto 8 bit. Instead no, is necessary a convertion using rescale before. Thx to point me in right direction.

[GRASS-user] Stream extraction from pseudo-elevation map using r.watershed
Hi, I tried something that was working at least several months ago, but somehow r.watershed has changed. What I am trying to do is to extract a stream network from a pseudo elevation map. This pseudo elevation map is created by getting the distance of each stream cell from to outlet in upstream direction (using r.cost). In addition, the streams are buffered (3 cells wide) with cells of a value that is much greater than the actual stream value. This map has several features: 1) The cell values for the stream are certainly decreasing in downstream direction (=elevation is decreasing) 2) The stream is carved into a valley (important at river junctions where two streams meet). So this should actually meet the requirements for r.watershed (at least it was working some time ago) to extract the stream and get the drainage directions (e.g. for other tools like r.stream.order etc.). Now, when I try to run r.watershed (GRASS7.1) I get following warning several times: WARNING: MFD: cumulative proportion of flow distribution not 1.0 but -0.00 Although I get a drainage map as output, no output is created for the extracted stream network. I am wondering what changed and why and if this is a bug in r.watershed or if I need to change settings differently. Attached you can find the pseudo elevation map as geotiff to try it yourself! The command I am using is: r.watershed -m --o elevation=pseudo_elevation drainage=drainage_test stream=stream_test threshold=3 My system: GRASS version: 7.1.svn GRASS SVN revision: 65534 Build date: 2015-07-02 Build platform: i686-pc-linux-gnu GDAL: 1.10.0 PROJ.4: 4.8.0 GEOS: 3.4.2 SQLite: 3.7.9 Python: 2.7.3 wxPython: 2.9.4.1 Any ideas or suggestions?
