I have two files, a DEM and a .GPX. How can I mix the two files so that the .gpx is part of the DEM (in black and white), but rendering the color at an elevation 10m higher than the DEM?
The color of the .GPX should be set to black and white, lighter or darker depending on how high it is above the DEM.
I tried with Raster > Conversion but I cannot see the output.
