#807: r.watershed doesnt consider longer distance to diagonal neighbouring pixels ---------------------+------------------------------------------------------ Reporter: aread | Owner: [email protected] Type: defect | Status: new Priority: major | Milestone: 6.4.0 Component: Raster | Version: 6.4.0 RCs Resolution: | Keywords: r.watershed Platform: All | Cpu: All ---------------------+------------------------------------------------------ Comment (by mmetz):
Replying to [comment:2 hamish]: > > how does the patch (or r.watershed for that matter) work with lat/lon locations? Tested only in real projections, should most probably use geodesic distance for lat/lon locations? I'm busy investigating the new patch for its behaviour in depressions, just to make sure I do not introduce another bug. Outside depressions it looks ok, flow directions are set as expected. > maybe that had something to do with the removal (????) > FWIW svn (cvs) history back to 1999 (~r1 to r3) can be found in the grass54 branch even if the history has been broken in trunk. Also the old ViewCVS is AFAIK still up & running (link on trac wiki page). The change happened between 1990 (grass32) and 1998 (grass40), I did not manage to find that commit :-( Markus M -- Ticket URL: <https://trac.osgeo.org/grass/ticket/807#comment:4> GRASS GIS <http://grass.osgeo.org>
