Proportional circle maps

I think proportional circle maps are really neat, and a user friendly way of understanding information. They use circles to represent data and figures of information on a given space. The picture shown has information about mexican population in the USA.

Choropleth maps

Choropleth maps are thematic in the sense that they use information from various regions and represent it through shadings and colors. The map I used for this example is of the state of Florida, and the percent of persons who are hispanic or latino.

Dot distribution maps

Dot distribution maps use symbols (dots) to represent an individual piece of information, which helps to display large multiples of individuals to reveal a larger group of information. This picture I used for an example is particularly interesting, because it shows the 1990 USA population, through light & electricity image. The validity of this picture and other similar pictures have been debated, as to whether they really are factual or not. Either way, it does portray a fairly good depiction of the US population.

Propaganda maps

Propaganda maps have misleading and biased information that is designed to sway the audience to believe a particular thing to be true. The map shown of hitler is not your stereotypical "map" but like we discussed in the beginning of the semester, pictures are maps as well. It is propaganda because the german letters below say (roughly) "he loves germany" and have a bird above his head to represent peace, and the clouds opening up behind him, almost giving him a jesus like disposition. We all know this was completely false.

Hypsometric maps

Hypsometric maps represent the elevation of the terrain through contouring, shading, tinting, and batching. The map shown uses hypsometric techniques to display the average annual rainfall in arizona, which makes the information more user friendly than if it were without colors and shades.

PLSS are maps used to divide public lands owned by the federal government. The PLSS map above has lines which are representations of the America's state boundaries which are supported federally.

A cadastral map shows the boundaries of a portion of land mass. The picture above shows the land divided into various private homes.
