This is a statistical map which depicts the percentage of change in residents of each state from the 1990 census to the 2000 census.

This is a mental map depicting the Los Angeles area. The map shows which area of the city are seen as most dangerous to residents. The map was created by a Professor at Purdue University, Sorin Matei. Interviews were conducted with people in six ethnically diverse neighborhoods to find out where these people felt the least safe. The darkest shades indicate the areas with the most perceived danger while the lighter areas are considered safer. This map does not necessarily correspond to where the most crime is, however it is not just facts which affect our perception of our surroundings.  http://web.ics.pudue.edu/~smatei/MentalMaps/explain.html

This map is a cadastral map from 1736. It was used to delineate where in Montville, Connecticut the Mohegan Indians were granted rights to live. It is interesting to note that Britain ruled that the Mohegans' land consisted of much more than this area in Connecticut in 1705, however, that ruling was not implemented on this side of the Atlantic, as can be seen here. This is a great example of how land partitioning is a social institution. The bottom of the map consists of a note from the county surveyor asserting the legitimacy of the map. This map was originally on HistoryNYC.com, a map vendor. http://historynyc.com/products.asp?cat=53

This is a topographic map of the Grand Canyon, approximately the area that the National Park resides in. Just having returned from a trip to the Grand Canyon, this map has significance for me. Note how closely the contour lines are placed within the canyon, representing the sheer cliffs and steep walls. Contrast that with the sparse contour lines up on the rim of the canyon where the land is fairly flat. This map originally came from a link on a professor's web page that teaches a class in Physics at Davidson University in North Carolina. http://webphysics.davidson.edu/faclty/dmb/py220/grandcanyon/jpg

Planimetric Map

This is a map of San Francisco made for tourists. I particularly like the use of a planimetric map here as it conveniently ignores that those tourists must do some strenuous walking up and down many hills in order to get anywhere.
