I have a georeferenced orthophoto and a DEM as tiff-file. For my further workflow I want to export x,y,z (x,y from the orthophoto and z from the DEM).
I already managed to create a point layer and click a couple of points, which I want to use as control points. After clicking I exported the new layer as CSV & turned GEOMETRY on AS_XYZ.
It already works fine for X & Y, but not for the Z-Coordinate. I guess, because the height is saved as an attribute in the DEMz in cm.
Does anybody have an idea how to connect x,y and z?
(the DEM and orthophoto aren't snapped).

    look in the processing toolbox for the point sampling tool. – csk Jan 14 at 17:47
