Isoline Maps




source: http://www.lib.utexas.edu/maps/atlas_mexico/

Isoline maps are drawn with continuous lines with each line representing a constant value. This is an effective way to display elevations where areas of same or similar elevation are drawn with the same continuous line. The map above shows average annual precipitation in Mexico - where you see a continuous line you can assume the same average annual precipitation.
