Univariate Choropleth Map

http://www.cdc.gov/pcd/issues/2007/oct/07_0091.htm

This map depicts the poverty rates for people all over the United States. It is a univariate map because it measures only one variable.

Unclassed Choropleth Map

http://www.agocg.ac.uk/reports/visual/casestud/dykes/issue3_1.htm

Unclassed choropleth maps allow for colors and shading without having to classify exactly what the colors mean. That makes this type of map widely unpopular because it makes the maps purpose unclear.

Classed Choropleth Map

http://personal.uncc.edu/lagaro/cwg/color/color_symbol.html

Classed choropleth maps used different shades of color and tenting to determine different measures of something. This map of North Caroline show how much money is spent per student in the state on public education. The data is done on a county-by-county basis.

Range Graded Proportional Circle Map

http://pubs.usgs.gov/fs/fs-004-03/

This map takes a look at water observations made by Lewis and Clark. The color of each circle denotes the color of the water (grey being no distinct color was noted). Within each circle is a triangle, and within each triangle, a black dot. The location of the black dot inside of the triangle describes the composition of the seabed.

Continuously Variable Proportional Circle Map

http://lib.utexas.edu/maps/thematic.html

This map uses different sized circles to show how much industry is in a certain area. Bigger circles are equivalent to areas with my industry and vice versa. Within each circle, each type of industry that is in that location is represented by different colors. This makes it easy ti see which industries dominate which areas.

Star Plots

http://commons.wikimedia.org/wiki/Category:Star_plots

Star plots are used to measure many variables at one time. Each variable is stationed at a point around a circle, then the results are placed along lines leading out to each variable. The leads to a star-shaped graph.

Correlation Matrix

Lorenz Curve

http://www.unc.edu/depts/econ/byrns_web/Economicae/Figures/Lorenz.htm

The Lorenz Curve is often used in economics and is often used to show income distribution. The straight line on the top shows what the income would be if it was perfectly equal. The lower line shows what the actual income is line, leaving the area that is shaded red in the middle to be the area that creates the inequality between the two.

Index Value Plot

http://waterwatch.usgs.gov/?m=pa07d&r=ma&w=pa07a%2Cplot

Choropleth Maps

http://www.pop.psu.edu/gia-core/divorce.htm

Choropleth maps display different statistical values for a variable in different colors or patterns. In this map, the increase in the divorce rate is measure, first by state, then by county. The brighter the shade of blue, the greater the increase in divorce rate.

Dot Distribution Maps

http://operationmilitarykids.ohio4h.org/resources/bycounty.html

Dot Distribution Maps (also called Dot Density Maps) use small dots to represent some statistical data characteristic about a particular area. On this map of the state of Ohio, each dot represents the place where a military family resides. One could deduce, from looking at this map, that the areas with the most green would be locations of military bases.

Propaganda Maps

http://strangemaps.wordpress.com/2006/11/23/38-the-world-according-to-ronald-reagan/

Propaganda maps are used, often by the government, to influence the general public of a certain idea. They manipulate what might be real and shape it into something that will lead an individual to feel a certain way about the topic at hand. This map demonstrates conflict taking place during the Cold War when Ronald Regan was president. This map was created to be seen by Americans.

Hypsometric Maps

http://www.earthexplorer.com/2009-03/Subsurface_Geology_Challenges_Goiania_Metro.asp

PLSS Map

http://www.rootsweb.ancestry.com/~alfrankl/landrecords.htm

A PLSS (Public Land Survey System) map is used in the United States by the federal government to divide areas of public domain into subsections and then sub-subsections, and so on and so forth. Within this system, land is typically divided into areas of 6 square-miles, initially, and then continue to be further divided. Markers are then placed on each corner of the square to help mark the territory. This map has divided Franklin County, Alabama into differed sections, and has numbered each column and row of the grid so that different parts of the county are more easily found.

Cadastral Map
