Map #43: Accumulative line graph or Lorenz curve
The lorenz curve above shows the population's income according to percent. The straight line is the estimated distribution if the data were more equal. The curved line is actual data.
http://www.answers.com/topic/lorenz-curve
http://www.liv.ac.uk/ssci/research/single_molecule_electronics.html
This displays a lorenz curve for a chemistry experiment. The dark line shows the actual distribution of data, where multiple molecules reacted in the experiment. The curved line shows a molecule that did not react, showing exponential decay with distance. I0 is the beginning of the experiment, Sw is the distance the molecule traveled due to the current, Iw represents the plateau of the current, and the slope at Sw is where the molecule lost contact with the current and therefore decreased movement.
Map #42: Index Value Plot
http://waterwatch.usgs.gov/?m=pa07d&w=plot
This portrays the average flow of a stream in the United States from 2001 to 2009. The higher the point, the wetter the stream, and the lower the point (under the solid straight line), the drier the stream. This is not a data graph for absolute numbers. Index is measured from climate differences or in the land's differences.
Map #41: Scatterplot
http://www.panopticon.com/products/scatter_plot_data_visualization_software.htm

There are no names for this population with 1 to 2 letters in them.
Map #34: Box Plot Map
http://www.mathworks.com/access/helpdesk/help/toolbox/stats/f4801.html
Box plots show a quick summary of data and are helpful with two sets of data. The red line in the middle of the blue box is the Median. The red lines towards the bottom show data that are scattered and do not fit in with the majority of the values. The top of the blue box is a line representing the median and average while the bottom of the box is the 25th percentile.
Map #33: Stem and Leaf Plot Map
http://www.eduplace.com/math/mhm/5/06a/index.html

Each design is measured on mass, task completion, actuator saturation, collision, accuracy, and trajectory completion.
Map #29: Black and White Aerial Photo
http://www.rolfealumni.com/whatsnew2003.htm
The black and white aerial photos are sensitive to the same wavelengths as us and much less of a differentiation between land and sea in these types of photos than in the infrared ones. This black and white aerial shows the area of Rolfe High School in Ames, Iowa.
Map #28: Infrared aerial photo
http://www.aerialarchives.com/Aerial-Maps-of-Sonoma-County.htm
These maps can be used to show changes to the environment, the condition of forests, oceans, and bays. This shows false color because the Infrared wavelengths on the film cannot be seen by humans. Vegetation and bodies of water are displayed in red, while the other areas are buildings, parking lots, and soil. This is a map of Sonoma County, California.
Map #27: Statistical Map
http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/census.html

Map #26: Propaganda Maps
http://www.victoriansatwar.net/archives/maps_2.html
Propaganda tells half truths about a party to make them appear worse than they really are, usually because they want to manipulate that party into doing or thinking something. This shows a satirical map of Europe at war in 1914 during WWI. These countries are portrayed as having dog-like behavior at this time. Germany is shown as a hostile Dachshund, Austria as an annoying Mongrel, Belgium as an minuscule Griffon, France as a fancy Poodle, the United Kingdom as a Bulldog that's biting Germany's nose. Other surrounding parties were displayed as things such as a Spanish bullfighter (Spain), a Greek man ready to stab someone in the back, Russia as a bear with a steamroller, and many others. These countries are represented this way to show how everyone was portrayed during the time of this war.

Map #24: PLSS map
http://iagenweb.org/harrison/twp/rangemap.htm
This is Harrison County, Iowa's PLSS map system, which divides the county into a grid-like pattern. It shows the Civil Townships (used in the U.S. Census)-which are all the colored areas- and it shows the Public Land Survey System Township and Ranges outlined in red. The names in purple are the towns. The PLSS help identify land ownership by dividing it into 36 squares (from northeast to southeast), each section with 640 acres. The smallest squares represent a quarter quarter section and the number in each of these sections tells the quarter section quadrant and quarter quarter section quadrant it belongs to.
Map #23: Isolines
http://mapmaker.rutgers.edu/355/links.html
The isolines represent lines of equal value-in this case, Temperature in degrees Fahrenheit for Australia.
Map #22: Range Graded Proportional Circle Map
http://www.neiu.edu/~ejhowens/377/examples.htm
These maps are mapped with a circle instead of a dot and the size of the dot tells how dense the population is in that area. This range-graded proportional map displays only a set number of circle sizes used in the map (four). It shows the estimated number of Filipinos living in these particular states in 2000. The majority of the Filipino population resides in Texas.
http://www.gis.unbc.ca/courses/geog205/lectures/theme_map_pd/index.php
This is also a range graded Proportional Circle Map because it uses a set number of circles rather than a variety in circle size.
Map #21: Dot Density Map
http://www.mpassociates.gr/software/distrib/science/golden/mapviewer7.html
Dot density maps usually use non-proportional point symbols that do not vary in size. This shows Arizona and each county's population, where one dot equals 10, 000 people. The majority of the population resides in Maricopa county in Arizona.
Map #20: Isopleth
http://www.envisci.ucr.edu/ensc176/es176_2003/ENSC_176_Summer_2003.html
Isopleths connect points which have the same numerical value of a certain variable. For example, this isopleth map shows the percentage of CO2 concentrations in the soil in 1999. The green lines represent tree kill boundaries. As you can see, the highest concentrations of carbon dioxide area found in the middle of the tree-kill area.
Map #19: Isopach
http://www.volcano.si.edu/world/volcano.cfm?vnum=1505-10=&volpage=var

Map #17: Isotachs
http://aurora.aos.wisc.edu/tropical/index.shtml
The colored areas represent isotachs, which show areas of equal wind speed with intervals of 10 knots. This map shows areas of higher wind speed around the North Atlantic Ocean and wind speeds from 20 to 30 knots all over North America.
Map #16: Isobars
http://seakayaking.wordpress.com/2006/11/
Isobars represent lines of equal atmospheric pressure. In isobaric maps, winds flow counterclockwise around lows, clockwise around highs, and parallel to isobars. The closer the lines, the stronger the winds and the further apart the lines, the weaker the winds. The dashed lines are the geopotential heights, where 500mb of air pressure is reached. People had to seek shelter from these 20 knot winds while sea kayaking in Japan.
Map #15: Cadastral Map
http://www.flyingemu.com/ccosta/bloy.html
These types of maps show the land-parcel boundaries that tell the location, shape and size of land parcels within the system. They also have a parcel number and identifier system, used to identify what land belongs to whom and is a basis for property rights. This cadastral map shows the breeding status of Black Oystercatcher birds in Contra Costa County, California. This type of map helps locate the birds more accurately because it is divided into a grid system.
Map #14: Topographic Map
http://geology.isu.edu/geostac/Field_Exercise/wildfire/topography.htm
