Isopleth



http://www.cbr.washington.edu/papers/jim/draft.html


Isopleths are also comprised using contour lines which generalizes and simplifies data with a continuous distribution. We use isopleth maps to depict population densities, temperatures, pressures etc.  This particular map shows the wind velocity by month and latitude averaged over several years. The data here is shown as a third dimension on the map.
