Classed choropleth maps

Classed choropleth maps the same as choropleth maps in the sense that they use shading to determine where each area falls into, but in classed cholorpleths there is a set range for each shade to fall into. Instead of the viewer having to guess what the exact number is, the color will match up with a certain amount such as the map above. http://hosting.soonet.ca/eliris/remotesensing/bl130lec7.html
