I have vector data for a large area that I have split into 2km x 2km layers using Create Grid, Intersection, and split, within the vector menu. I've downloaded STRM data for the whole area. I'd like to be able to use the same grid to chop up the height data into 2km x 2km pieces so that I also have 2km x 2km height data pieces that match my vectors pieces. At present the STRM extend is way larger than my whole 20km x 20km vector layer.
Is there any way I could trim the .hgt layer to match the extent of the large vector layer, then split on a 2km x 2km grid?
