Hypsometric maps are used to show relief on the surface through a third dimension type such as coloring and shaping, contour lines, and/or raised relief. This is a map of British Columbia that expresses elevation. The elevation is expressed through a color scheme on the map correlated with the scale on the right side of the map.
