Bilateral graph
Bilateral graphs display data when both positive and negative values are shown. This graph is of the Democrat candidate approval ratings for April 2007 through January 2008. In case this is too small: dark blue is Obama; red is Edwards; yellow is Clinton; lt blue is McCain; golden is Romney.
Nominal area choropleth map
Nominal area choropleth maps shows groups without any particular order. This is a map of Greece.
Unstandardized choropleth map
Unstandardized choropleth map uses real data and not averages. This map shows the Russian population in 2001.
Standardized choropleth map
http://upload.wikimedia.org/wikipedia/commons/thumb/7/78/USA_states_population_density_map.PNG/800px-USA_states_population_density_map.PNGThis is a standardized choropleth map of the population per square mile per state.
Univariate choropleth map
Univariate choropleth maps display a single attribute such as soil type, land use; or in this case, percentage of people.
Bivariate choropleth maps
http://proceedings.esri.com/library/userconf/proc99/proceed/papers/pap171/p1712.jpgBivariate choropleth maps uses color to solve a problem using longitude, latitude and 2 statistical variables. This map shows the median house value in Ohio counties.
Unclassed choropleth maps
Unclassed choropleth maps assign shadings in proportion to data values so these maps don't have to classify the data.
Classed choropleth map
http://personal.uncc.edu/lagaro/2101/2101_ProjectsS2001/beefmethaneJMK.gifClassed choropleth maps use data in order to create classes. This is a map of beef cattle emissions in North Carolina in 1992. The color shading shows tons of emissions in the various counties of North Carolina.
Range Graded Proportional Circle Map
http://www.neiu.edu/~jrthomas/377/circle.jpgRange Graded Proportional Circle Map are used anytime you want to show relative magnitudes of phenomena. This map was created in 1990 to show the Mexican population in the western United States.

Continuously variable proportional circle map
Continuously variable proportional circle maps utilize circles to create point data. The circles are in proportion to the variable being measured. This map is obviously of Canada. The circles represent the population distribution in 1980.
DOQQ
A DOQQ is used to measure true distances. It is an accurate representation of the surface. The DOQQ adjusts for topographic relief, tilt of the camera,etc. This map is of a small section of Washington, DC.
DEM
http://upload.wikimedia.org/wikipedia/en/c/cd/Oregon_DEM_relief_map.gifA Digital Elevation Model (DEM) is a digital representation of terrain. This map was taken by the USGS of Oregon.

DRG
http://www.goldensoftware.com/newsletter/50/Issue50Sgps5.gifA Digital Raster Graphic (DRG) map is usually created by the USGS (US Geological Survey). This map shows a proposed hiking trip route. In this map, purple represents the start of the trip and red is the end. The green, yellow and orange show the track at the north end of the map, showing the order of the points.
Isopleths
Isopleth maps generalize and simplify data through 3-d. These types of maps are common for mapping surface elevations, rain level,etc. This map shows the rain fall for New Zealand.
isopach
http://www.searchanddiscovery.com/documents/2007/07022lash/images/ani03.gifIsopachs are contour lines of equal thickness. An isopach map illustrates this thickness with a stratum. This map shows Geneseo Shale (thickness is measured in feet).
Isohyets
Isohyets are lines that join points of equal precipitation. This map shows rainfall using data used from measurements taken at sites where rainfall is monitored by the Taranaki Regional Council.
Isotachs
Isotachs are lines of constant wind speed. This map is an isotach analysis for Hurricane Ava (1973). The solid lines show the direction of the air flow and the dashed lines (isotachs) show the windspeed.
Isobar
Isobar maps are maps that are illustrated with contour lines. These lines join places of equal average atmospheric pressure reduced to sea level for a specified period of time. This map is showing the lines of constant atmospheric pressure.
LIDAR
LIDAR is a laser ranging technique that is used for high-resolution topographic data. This map shows the ocean floor in 3-d imagery.
Dopplar radar
This is a doppler radar for July 23, 2009, from the Weather Channel. The green in the map shows rainfall and its predicted path.

http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/landweber_version_16.gifThis statistical map is a map showing the international connectivity for June 1997. Through the use of statistical data and color coding, the map shows the areas with internet, email only, etc.
Cartograms
There are 2 types of cartograms: area and distance. I have chosen an area cartogram. Each county was rescaled in proportion to its population and reflects the results of the 2004 US Presidential election (popular vote).

Flow maps are a mix of maps and flow charts that show the movement of objects from one location to another. This map is a Telecommunications Flow Map that shows the volume of international telephone calls between nations.
Isoline Map
Isoline Maps use continuous lines to join points of the same value. These type of maps are commonly used to portray high and low weather patterns. This map was taken from the Doppler Radar at 10:50 a.m. on July 9, 2009.
Proportional Circle Map
Proportional Circle Map show pie symbols to represent quantifiable data which is proportional to the amount represented relative to other symbols of the same type on the same map. The symbols in this map represents major industries in Germany.
Dot Distribution Map
Dot distribution maps portray quantitative data as dots. The pattern of dots reflect general locations where a particular phenomenon most likely occured. This map shows the locations of Millennium Medical Products Inc.
Choropleth Maps
Choropleth maps have areas that are shaded in proportion to the measurement of statistical variables, such as population density. This map is from the Department of Agriculture which gauged the acres of hay in the United States in2002.

Propaganda maps
Propaganda Maps are used to incite emotions in others towards a particular cause. Hitler believed that it was the manipulative power over one's emotions that would be of an enormous value to him. Propaganda maps have also been used to extend ideas to the illiterate masses. This map was created by the French to show the ports and shipping centers that were bombed by the Luftwaffe.Hypsometric Maps
Hypsometric maps are maps that show elevation by contours or through shading, tinting or batching. This is a map of Hawaii showing the island and the varying elevations.

PLSS Maps are used for titles and deeds of land. PLSS Maps were created under the Land Ordinance Act of 1785. The basic units of area are section and township.
Cadastral Maps
Cadastral maps include details of ownerships, precise location, and value of individual parcels of property. They are often used in conjuction with other records such as property records, title registery, etc.
