#3860: GRASS GIS producing different slope than GDAL
------------------------+-------------------------
Reporter: mazingaro | Owner: grass-dev@…
Type: defect | Status: new
Priority: major | Milestone: 7.6.2
Component: Raster | Version: unspecified
Resolution: | Keywords: slope
CPU: x86-64 | Platform: Linux
------------------------+-------------------------
Comment (by mlennert):
The first difference is between gdaldem and r.slope.aspect results at the
resolution of the input data.
The second difference is between two runs of r.slope.aspect, one at the
resolution of the input data (10m), one at half that resolution (5m). It
is meant to show that differences because of different region settings are
probably much more significant than differences between the two programs.
I personally would not consider an average difference of almost 4 degrees
"normal" if I expected same results...
