I am trying to produce a multidirectional hillshade from ASTER DEMs in QGIS. basically I am trying to achieve something similar to this
which is a screenshot from this layer https://services.arcgisonline.com/arcgis/rest/services/Elevation/World_Hillshade/MapServer but there the problem is that I can not print maps in the high resolution I need. so i thought i do it myself but when I apply these settings
that work for other DEMs very nicely I get a terrible image for Aster.
I kind of suspect it has to do with the fact that I can not apply the scale correction factor of 111120 (in the Scale ratio vert. units to horiz. box) which I usually do for aster. any thoughts for how I can make this work?
