Trying to use raster extraction clipper to prepare a selected area of the map for generating contours - keep getting the error message:
ERROR 1: TIFFOpen:everest_gmted30.tif: Permission denied
Any clues on what to do about this?
I encountered this problem as well and it took me a lot of time to figure it out. Turned out the solution was simple (but not obvious). Instead of writing just the filename in the space for "Output file", you should write the full filepath.
Do this by 1) clicking on "Select..." 2) type the filename in the "File name: " slot 3) click "Save"
After you're brought back to the "Merge" window, click "OK".
