Hello. I'm having a hard time finding how to do this. Basically I have a DEM in Geotiff format. I want to draw polygon over elements and cut them out of the DEM. Let's say I want to create "holes" on the image.
I found the Crop option but isn't there one to Cut?
Thanks in advance.

Hi,
You could draw the bounding box for the geotiff and add your polygons as islands .Then you can crop to that.
All the best
