Complete beginner here. Any help or pointers very welcome.
I've trying to create a DEM for the Yorkshire Dales National Park in the UK (I know I can download extant DEMs!).
I've downloaded the OS Open Zoomstack (Geopackage), and added a contour layer to my map.
I've Googled and spent over an hour looking and experimenting but can't make progress.
Thanks for your help!
Thanks for this, Dan.
The contour data is vector, so clipping seems to select either contour vectors that are wholly contained with the area specified, or else the entire extent of the vector beyond the area specified. This latter effect creates a spaghetti mess of a selection, rather than a neat box.
