Hypsometric Map

Any surface map showing relief and some type of three dimensional data can fall under the category of a Hypsometric map. Coloring, shaping, contour line, and raised relief are all ways this said third dimension can be expressed on these types of maps. The example above is a map showing relief in California. Changes in elevation are represented by different shadings of color.
