Hypsometric maps show the surface but add a third dimension to the picture by using relief, whether they do so using contour or raised lines, colors, etc. This map depicts the study of "annual average accumulated degree-days above a 40 degree F." The number of accumulated days is the third dimension in the map and to distinguish between the numbers, they used a color gradient. Areas shaded black have zero days while areas shaded in a bright lime green have up to 13500.
