#2980: r.watershed and max_slope_length ---------------------+------------------------- Reporter: mankoff | Owner: grass-dev@… Type: defect | Status: new Priority: normal | Milestone: 7.0.4 Component: Raster | Version: 7.0.1 Keywords: | CPU: OSX/Intel Platform: MacOSX | ---------------------+------------------------- I'm not sure if this is a bug, but I think it might be. The {{{max_slope_length}}} seems to have no effect in the {{{r.watershed}}} program. Below is an example that should work on the NC data set. I'd expect there to be different accumulation maps based on setting {{{max_slope_length}}}, but they appear identical.
{{{ r.mapcalc "rain = 1" r.watershed -s -a --v elevation=elev_srtm_30m accumulation=acc drainage=fdir flow=rain r.watershed -s -a --v elevation=elev_srtm_30m accumulation=acc.len drainage=fdir.len flow=rain max_slope_length=15 g.gui.mapswipe first=acc second=acc.len }}} Also mentioned at https://www.mail-archive.com/grass- u...@lists.osgeo.org/msg31665.html and https://gis.stackexchange.com/questions/187312/what-does-the-max-slope- length-option-do-in-grass-r-watershed -- Ticket URL: <https://trac.osgeo.org/grass/ticket/2980> GRASS GIS <https://grass.osgeo.org> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
