This map shows the population from ages 14 and under 2006 in Canada. Standard choropleth maps convey standardized data based on percentage of area.
Univariate choropleth map shows only one specific set of data. The map above shows the percentage of people living in poverty, by county, in the Untied States during 2000.
A Classed choropleth map is type of thematic map in which are colored or shaded to reflect the values of the different a classes mapped. The image above is taken from a 2000 Census of the number of male per 100 females in the U. S. by state.
The image above is in "grey scale" format it represents the population distribution of Canada in 1980 with the largest circles representing the most populated areas. The data is split into groups while using classification procedures which is common in choropleth mapping. A Range graded proportional circle map is a circle map that uses circle size in relation to data ranges or groups.
Digital Raster Graphics (DRGs) are scanned images of U.S. Geological Survey topographic maps. The image inside the map is georeferenced to the surface of the earth, which makes it possible to use DRG as a map layer in many GIS software. The DRG image above is the city of Austin, Texas.
Isopach maps are a type of a contouring map that uses lines, also known as isolines to represent rock or sediment thicknesses. This image shows sediment elevation data from East Asia which was compiled by the Committee for Coordination of Offshore Mineral Resources Prospecting.
Isobars are a type of contouring map the use rigid lines to represent air pressure. Isobars join points of equal pressure, measured in mb (millibars). This map shows the flow of air in relation to high and low pressure areas.
LIDAR (Light detection and ranging) systems are one form of remote sensing. In this image, scientists use computer generated 3D visualizations of multiple LIDAR data sets to represent new levels of archeology data analysis.
Doppler Radar is a type of remotely -sensed map which utilizes microwaves to track direction and speed of suspended water droplets in the atmosphere. This image is taken from a Doppler Radar showing the movement of Hurricane Katrina on August 28, 2005. 
The Statistical map above shows the total number of flood claims by state made between September 2004 and September 2005 according to the National Flood Insurance Program. Statistical maps can communicate relative map scale based on the data. Distances and areas can maybe be distorted in relation to population or values.
Cartogram maps are created by substituting standards of measure for distance or area. In this map country sizes are represented by the number of plant species and not actual land mass.
The U. S. Public Land Survey (PLSS) System is a systematic land partitioning system which covers most of the United States. Areas of the U. S. which fall outside of the PLSS system are considered to be unsystematic. This image was taken from the Federal Geographic Data Committee's website. It shows the progress of the committee's standardization of the PLSS in the United States as of September 2008.
Cadasteral maps are used to facilitate land owenership. In this example, we see a map survey of Wien the capital Republic of Austria taken from a collection created under rule Emperor Franz I, 1817-1861.
Topographic maps are a type of Contour map that uses contour lines to portray relief. Additionally, they capture a 3 dimensional aspect of terrain on a 2 dimensional surface. In this map we see the elevation of mountain Mt Passaconway and Mt. Tripyramid. Showing the elevation and a 3 dimensional view; its clear to see Mt. Passaconway is higher.
Mental maps are created from a person's memory of a place or event. This map is described as "going from my house to university". This picture depicts places the author is very familiar with.
