Infrared photographs also can show contrast of water. That can be seen in a better example on the link above.

U.S. Public Land Survey System

http://www.ak.nrcs.usda.gov/technical/plss.html
PLSS is set up by first establishing an initial points for a region. Most of the United States follows this system but the original thirteen colonies, Texas, parts of Florida, and a few other small locations. It is usually divided into 6-square mile townships and then townships are divided into 36 1-mile squares.

The site below also contains some great information about the PLSS process and maps to help gain a deeper understanding.

Digital Orthographic Quarter Quads

http://www.tceq.state.tx.us/gis/doqtnrcc.html

Digital orthographic quarter quads or DOQQ combines the mixture of an aerial photograph with the geometric qualities that can be found in a map. These maps are useful because they display some features that can be left out of or generalized in a standard map. They can also be used to find direct measurement of distances, areas, angles, and positions.

Digital Line Graphs

Mental Map

http://fasica.altervista.org/adam/adam_en.htm
Mental map are very interesting and very personal to a person. A mental map is one's internal map of a location. They are abstracted representations of real locations.The site listed showed multiple maps of Amsterdam by different people. The point of the exercise was to show how one's interpretation of a city is different then the actual location and from person to person it can differ.

Kriging Map

http://www.gisdevelopment.net/proceedings/mapindia/2006/environment%20and%20forestry/mi06envi_148.htm

Proportional circle map

http://geographyfieldwork.com/DataPresentationMappingTechniques.htm

This is another example of a point pattern map. A proportional circle map is able to give more information in the circles since they are pie graphs.  The circles themselves give information and then is able to be broken down more with the graph. In this map there are five different circle possibilities.

Dot Density Map

http://www.flutrackers.com/forum/showthread.php?t=6379

This map is fulled with multiple information but is also a good a example of a dot density map. In this map one dot equals 7 herds or swine farms in a area. It is to display the effect of the virus H3N2 in the areas. To me this map has more of a clustered look since some farms are far apart, while some areas are heavily populated.

Range-graded Proportional Crcle Map

http://www.neiu.edu/~ejhowens/377/examples.htm
Proportional map is a point pattern map, instead of displaying information by dots it uses a circle to do so. The circle size relates to the variable being measured and there is a set number of circles used. The above map is displaying the Filipino population in selected states and it is using a set of four circles.
