Re: [GRASS-user] hydro-flatenning process ?
From a dem file (breaklines), i would like apply hydro-flatenning process. Is it possible to do that with grass? I would like define an hydrologic topology on my DEM. Each cellul of my raster should have a topologic component. My goal is to flatten waterway areas 's values. r.in.xyz http://grass.osgeo.org/grass64/manuals/r.in.xyz.html r.surf.idw http://grass.osgeo.org/grass64/manuals/r.surf.idw.html v.surf.bspline http://grass.osgeo.org/grass64/manuals/v.surf.bspline.html v.surf.rst http://grass.osgeo.org/grass64/manuals/v.surf.rst.html ? - best regards Helmut -- View this message in context: http://osgeo-org.1560.x6.nabble.com/hydro-flatenning-process-tp5065095p5065707.html Sent from the Grass - Users mailing list archive at Nabble.com. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Although a feature request was filed 4 years ago: http://trac.osgeo.org/grass/ticket/793 You could probably generate hydro flattened surfaces separately and combine them with the DEM manually using the raster calculator, but unfortunately I don't think there is a one click button. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/hydro-flatenning-process-tp5065095p5065874.html Sent from the Grass - Users mailing list archive at Nabble.com. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
