Cartograms

Cartograms are maps in which area is distorted. Like in this map of the US, the states are not displayed in the correct size instead they are shown according to the population of the counties. http://upload.wikimedia.org/wikipedia/en/4/47/Cartlinearlarge.png

Flow maps

Flow maps use lines to show movement. The thicker the line the more that is being moved and vise versa. This map is showing international telephone traffic. http://www.mundi.net/maps/maps_014/august2000_small.gif

Isoline maps

An isoline map liek the one shown is a 2D representation of something 3D. In the example here the map is showing a peak and a crater. http://www.sfei.org/ecoatlas/GIS/MapInterpretation/images/fig219.gif

Proportional circle maps

A proportional circle map uses circles to show data. For example, in this map shows internet use in Europe and the larger the circle the more people that use the internet and smaller the circle the less the people that use the internet.http://www.geog.ucsb.edu/~jeff/gis/proportional_symbols_files/map2.jpg

Choropleth maps

Choropleth maps are another one that use colors or shades to show proportions in information. My example shows the proportion of males per 100 females in the United States according to the 2000 Census.

Dot distribution maps

Dot distribution maps are most commonly used to show population, like in the example I used which shows the 2000 population of the US. The maps use dots to show information. When trying to show population, the more dots in the area, the more people that live there.

Propaganda maps

Here is an example of a propaganda map that is comparing infant mortality rates. A propaganda maps are directed at a specific audience and are designed to influence them to think a certain way. The information they give in the maps may or may not be true.
