Proportional Circle Maps

Proportional Circle maps are very similar to dot distribution/dot density maps in that they use shapes to depict numerical values on the maps. However, with a proportional circle map, the size of the circle is directly related to the data it presents, but not necessarily the area that it is covering. This particular example depicts zinc deposits found in a small portion of Canada. The larger dots presents a greater amount of zinc found in the soil. The amount of zinc is measured in ppm or parts per million. It also gives a legend for different types of deposits. The distances scale is also shown at the bottom of the map, so the map reader can determine how much area the map covers and what the actual distances is from circle to circle.

Choropleth Maps

This is an example of a cholopleth map. In particular, this map is a classed univariate cholopleth map. That means that the scale is divided up in equal 5 step intervals and depicts only one variable. This map shows the average spending by overseas residents in Great Britain in 2003. The scale is in millions of pounds. The map is shaded in pink. This is a good example of a cholopeth map.

Dot Distribution Maps

This map is a dot distribution map of the United States. It is based upon the 2000 Population of the US. Each dot represents 7500 people. With this particular style of map, the dots never change size, but remain constant in order to depict population correctly. The areas at are more white represent areas of our country with higher populations. This map shows that most of the country's population is concentrated on the east coast, especially in the New England states.

Hypsometric Maps

Hypsometric maps are surface maps that depict relief or elevation. This can be shown via color, contour lines, or raised relief. This particular map uses color to show elevation in a Cuban Archipelago. The scale is 1: 1,000,000. It shows elevation from 1 to 1970 and bathymetry from 0 to >>-6000. The shading gives a three dimensional view, which helps to portray the elevation depicted on the map.

PLSS Maps

PLSS Maps are created from the Public Land Survey System, which divides the land of the United States into ownership. It is a prime example of systematic land cadastral system. This map shows the partitioning of Ohio into various sections based upon a system that was not fully developed. It is not based upon the Principal Meridians. The sections that are shown the Virginia Military Survey, the Ohio Co. Purchase, and the Connecticut Western Reserve, to name a few.

Cadastral Maps

Cadastral Maps are maps that shows ownership and boundaries. This particular map is a map of Delware County in Delware, Ohio. The sections are color coordinated in order to show the boundaries. The sections are also clearly labeled with names in order to give more distinction of the ownership. This is a form of a land partitioning system.

Thematic Maps

Thematic maps are used to represent particular aspects of a region. There are many different types or methods of thematic mapping, including chloropeth, isarithmic, dot, and proportional symbols just to name a few. This particular map is a chloropeth map that shows the median age of the population in various states. The color scheme ranges from pale yellow to dark green in order to indicate the ages. This map shows only the northeastern part of the United States.
