Elevation can be displayed in many different ways, with one particularly popular derivation being the hillshade (also called “relief representation”). Other options for displaying elevation include contouring with or without hypsometric tinting, spot height labels, and, of course, the 3D oblique effect (which is really 2.5D if you want to get picky about it). (See Figures 6.37 and 6.38 for color suggestions.) hillShade
