This question already has an answer here:
I'm working on a student project trying to make a slope map with degree values. I downloaded a DEM file from a map service and used the raster ->analyze(tool)->terrain model and got the model. Now I would like to make a slope map
I googled it and found Calculating slope in percentage with QGIS
The second answer seem to have the solution, but I'm simply too much of a beginner to quite get what I have to click, step by step, to do this. He links to gdaldem
How do I make the operation to get the percent slope values?
