Statistical Map
Statistical maps represent different statistics for different areas. There are several different kinds of statistical maps such as a dot, proportional or choropleth map.
This is a map of the United States illustrating the percentage of persons living in each state who are uninsured between 1990 and 1993.
Thematic Map
A thematic map is a map or chart especially designed to show a particular theme connected with a specific geographic area. These maps might portray physical, social, political, cultural, economic, sociological, or any other aspects of a city, state, region, nation, or continent.
This map shows the number of Hispanics/Latinos living in the state of New York in 2000.
Topograpic Map
A topographic map is characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods.
This is a map of the Atlanta, Georgia metropolitan area’s highways and major roads.
Proportional Cirle Map
A proportional circle map shows data in proportion to the size of the circle. The larger the number is, the larger the circle is on the map.
This map shows the Mexican population of the Western United States. The smaller the size of the circle represents the small amount of Mexican residents for the state.
Propaganda Map
Propaganda cartography can be created and defined by their function. If maps are created for political propaganda measures, it can according to this categorization be identified as cartographic propaganda.
A propaganda map is used to influence people to change their beliefs about a certain thing. This is a reflection of Ronald Reagan’s point of view (it’s us (U. S.) versus them (USSR) theory during the Cold War Era.

The map shows geographic objects, natural and cultural physical features, and entities without topographic features such as roads, buildings, and bodies of water. A planimetrically accurate map showing planimetric detail and other general features shows accurate horizontal distances between features.

Choropleth Map
A choropleth map is a thematic map in which areas are shaded and shows the measurement of the statistical variable being displayed on the map, such as population density or per-capita income. Choropleth maps provide an easy way to visualize how a measurement varies across a geographic area or it shows the level of variability within a region.

Cartogram Map
http://www.viz.tamu.edu/faculty/house/cartograms/PresVote.html
A cartogram is a map in which some thematic mapping variable is substituted for land area or distance. The geometry or space of the map is distorted in order to convey the information of this alternate variable.
This map illustrates the results of the popular vote in the 1996 U.S. presidential election. Each state is colored either a shade of red or a shade of blue, and is distorted either enlarged or diminished to reflect the number of votes each candidate received.
Cadastral Map
http://www.mcatoolkit.org/US_State_Maps/Maps_Florida.html
Cadastral maps are comprehensive registers of the metes-and-bounds real property of a country. Cadastres commonly include details of the ownership, the tenure, the precise location (some include GPS coordinates), the dimensions (and area), the cultivations if rural, and the value of individual parcels of land. Cadastres are also used by many nations around the world, some in conjunction with other records, such as a title register.
In the United States, Cadastral Survey within the Bureau of Land Management maintains records of all public lands. Such surveys often require detailed investigation of the history of land use, legal accounts, and other documents.This is a map of Florida is used by the nature conservancy in Marine Conservation Agreements. The map’s boundaries are county by county and the areas that are part of the conservation agreement are shaded blue.
