[Qgis-user] Hillshade Rough Blocks for 1m Rasters?

[Nicolas Cadieux]

Hi,

If your x and y distance unit is different from the z distance (like 
long lat degrees for x and y and meters for z), you will need a z 
Factor, or you need to save the raster in a crs that has x,y,z in the 
same unit (like meter).

You can also improve the look in the layer/Symbology/Resampling and 
select cubic for "zoomed in" and Average for "zoomed out".
