Hypsometric maps are three dimensional surface maps. These maps are used to show different elevations of the earth by using color, shading, tinting, and contouring. In the map above it shows raised relief by displaying the different elevation starting from sea level. The dark blue shows the depth of the ocean and the contrast of light blue shows the elevation rising. The same goes for the shading of the greens and browns. By looking at this map you are able to recognize the ocean, land, and mountain that are being represented in this hypsometric map.
