[Qgis-user] Hillshade as layer property vs. Processing Toolbox GDAL hillshade

[Priv.-Doz. Dr. Maria Shinoto]

Hi,

Today I tried making a hillshade from the raster data you helped me out today -- after filling empty pixels, everything looks great.

Now, when trying to set the layer symbology to hillshade, I got artifacts with the default setting and the recommend bilinear with medium. Looking for a solution, I found this conservation about the same issue (I think) from about 3 years ago; it seems to be a problem still today (working with QGIS 3.12).

       https://github.com/qgis/QGIS/issues/23859

So I tried the hillshade tool from GDAL in the Processing toolbox with identical setting, and everything looks great.

I think that the flawed hillshade in the easily accessible Symbology dialogue needs some work or a hint to the GDAL tool in the Processing toolbox. It is frustrating for someone who is new.

I add screenshots from the bad results in the Properties > Symbology dialogue and the raster image from which I started.

Anyway, it was great to have a solution easily at hand ;-)

Best,
Maria
