Generating a color relief raster is a one-liner with the
gdaldem color-relief command line. If you want something that's a little more visually appealing, we will perform a combination of a slope, hillshade, and some color relief. Our end result is a single new raster representing a merge of layers to give a nice visual effect of elevation relief. The results are going to look similar to the following image:
For this exercise, you need to have the GDAL libraries installed that include the
gdaldem command-line tool.
