I'm new to QGIS and using version 2.10.1-Pisa.
I have two raster layers created from ASTER DEM data. I have one for slope and want to create a binary layer where only pixels between 8 and 60 degrees are included. I've tried "Nepal_Mosaic_Slope@1" >=8 and "Nepal_Mosaic_Slope@1" <= 60 but it says crash dumped and closes QGIS?? Is there something stupid I am doing? Once I have done this I want to combine the result with a binary raster of elevation which I assume you can do with merge?
