similar to a few queries but really struggling to clip a DEM file from say USGS.
Going to Raster > Extraction > Clipper and then "select the extent by drag on canvas", does not work.
The process will continue for up to 1 hour then give error messages implying not enough storage?
I'm on QGIS 2.8 Tien, running a MacbookPro on El Capitan... didn't work prior to OS upgrade though from Yosemite.
Any ideas? Tried out thinking this and tried to clip after extracting contours, and then trying to clip by extent but this isn't possible at moment I think unless a tool is developed. My project is to Just make a file at 10km square of contours to input into Google Earth.
