What does the following mean, when I try to clip and save the result as a sqlite or other format?
Computed -srcwin falls outside raster size of 7807x4771
If you clip a raster on a vector layer, both must have the same coordinate reference system.
It is not enough to
Set CRS for layer in QGIS, because clipping is an external command.
Best practice is to look up the CRS of the raster, then rightclick on the vector layer -> Save As ... , apply the CRS of the raster to a new shapefile, and add that to the canvas.
