How does Z factor affect hillshade analysis in QGIS?
Scale and Z factor have no effect on hillshade analysis in QGIS. I used an SRTM DEM to create a hillshade in QGIS 2.2.0. However, the resultant hillshade seems to be vertically exaggerated. Also, changing the settings for scale and z-factor does not have any effect on the resultant hillshade.
How do I change hillshade on data frame?
You can change the illumination angle on the Data Frame Properties dialog box. This will be applied to the hillshade setting made in the Layer Properties dialog box but will not change any function properties when using the Hillshade function.
How do you change the gamma in hillshade?
Right-click Hillshade Function and click Properties. Click the Hillshade tab and edit the properties. Click OK to close the Raster Properties Function dialog box and click OK again to close the Layer Properties dialog box. Gamma can be used to help normalize the display and put more emphasis on lower elevations.

How to calculate slope of terrain in QGIS?
To calculate the slope, you need to use the Slope algorithm of the Processing ► Raster terrain analysis. Keep the Z factor at 1.0 Save the output as a file with the name slope in the same folder as the hillshade Now you’ll see the slope of the terrain, each pixel holding the corresponding slope value.
What’s the range for the hillshade raster layer?
Range: 0 to 360. 0 is north. Set the vertical angle (in degrees) of the sun, that is the height of the sun. Values can go from 0 (minimum elevation) to 90 (maximum elevation). Specify the output hillshade raster layer.
