Correlation matrix
A Correlation matrix describes correlation among M variables. It is a square symmetrical MxM matrix with the (ij)th element equal to the correlation coefficient r_ij between the (i)th and the (j)th variable. The matrix I found is in reference to lifestock genetics. I found it here http://www.livestockgenomics.csiro.au/Genome_to_Phenome/matrix_corr_gt1SD.png

Box Plot
A boxplot (also known as a box-and-whisker diagram or plot) is a convenient way of graphically depicting groups of numerical data through their five number summaries. The smallest observation, lower quartile (Q1), median (Q2), upper quartile (Q3), and largest observation. Q1, Q2, and Q3 form boxes, and the smallest and largest observations form whiskers. The one I found shows annual snow depth at Mathsville Ski Resort. I found it here http://edubuzz.org/blogs/nbhs3x1/files/2007/01/boxplot-2.JPG

Parallel coordinate graph
A parallel coordinate graph is used to plot large multivariate datasets. Each variable in the data plot is represented as its own Y Axis on the graph. A maximum point for each Y axis is selected, and they are scaled relatively to each other so that each variable takes up the same area in the graph space. The one I found shows baseball statistics. I found it here http://www.matthewtavares.com/baseball_report/graph_allteams.bmp
Triangular Plot
A triangular plot is a graph of 3 variables. It is most often used in geologic studies to show the relative compositions of soils and rocks, but it can be more generally applied to any system of three variables.

Scatterplot
A scatterplot is a summary of a set of two variables, usually drawn before working out a linear correlation coefficient or fitting a regression line. It gives a good visual picture of the relationship between the two variables. The scatterplot I found shows a wifes age in reference to her husbands age. I found it here http://cnx.org/content/m10949/latest/age_scatterplot.gif
Index Value Plot
An index value plot shows a variable's range within an index rather than at a specific point. The graph I found shows the water variables in North Carolina since 1999. I found the graph here http://water.usgs.gov/waterwatch/regplots/real/real_nc_2.gif
Accumulative line graph or Lorenz curve
Accumulative line graph or Lorenz curve is a graphical representation of the cumulative distribution function of a probability distribution. The graph I found shows the two variables as being "cumulative percent of income" and "cumulative percent of population" and shows the perfect equality reference line, related to the area of inequality. I found this graph here http://www.unc.edu/depts/econ/byrns_web/Art/Glossary/LorenzCurve.jpg

Unstandardized choropleth maps
Unstandardized choropleth maps use no order in their ranking, they use raw numbers. The map I found shows the amount of water withdrawls in million gallons per day for every state. I found this map here http://pubs.usgs.gov/fs/2005/3051/images/2000choropleth.gif
Standardized choropleth maps

Bivariate choropleth maps
A bivariate choropleth map displays two variables on a single map by combining two different sets of graphic symbols or colors. It usually illustrates the relationship between the two. The map I found (very outof focus) displays the land use, life expectancy, and GNP per capita in Africa in 1989. I found it here http://image24.webshots.com/25/3/32/3/286333203FPiEKt_fs.jpg
Unclassed choropleth maps
Unclassed choropleth maps assign shadings proportional to the data values so that these choropleth maps do not have to classify the data. The map I found shows the acres of vegetables harvested for sale in 2002 for every county in the United States. It has a scale to go along with it. I found the map here http://www.nass.usda.gov/research/atlas02/Crops/Vegetables%20and%20Melons%20Harvested/Vegetables,%20Acres%20Harvested%20for%20Sale-choropleth%20map.gif
Classed choropleth maps
A classed choropleth map determines height and shading or color intensity of the bar for each map classed. This would involve creating a classed frequency legend including a frequency histogram, a frequency curve, and shading. The map I found shows males to every 100 females, data taken from the 2000 census. Looks like Alaska needs a few more girls!! I found this map at http://my.ilstu.edu/~jrcarter/Geo204/Choro/map-AmFact-6eqint-orange-80pct.jpg

The one I found was taken of Washington D.C.. I found it here http://seamless.usgs.gov/website/seamless/products/1mdoqq.jpg
DEM
DEM's (Digital Elevation Models) are a digital representation of ground surface topography or terrain. This map shows Lake Tahoe in Nevada.

This map shows a LIDAR map after a landslide in Daly City, California in January 2007. I found this map at http://soundwaves.usgs.gov/2007/06/LidarExampleLG.jpg
Doppler Radar
Doppler Radar is something that I find useful in everyday life. I am deathly afraid of thunderstorms and tornados (having been in a tornado when I was 12), so anytime the sky looks even hintingly dark, I turn on the National Weather Center doppler radar. Doppler radar shows the amount of precipitation in any given area. It is also used to predict tornados and hail using the circulation of rain and cloud coverage. This map shows a very bad thunderstorm in Texas in 1997, that actually produced numerous tornados. I found this map at http://www.srh.noaa.gov/images/lub/events/2007/20070417_hailandtornadoes/radar_srm_slaton.jpg
Black and White Aerial Photo
Black and White Aerial photos are normally used for personal or reference purposes. This photo shows Liverpool, UK in 1941, from 1800 feet and I found it being shown for cultural remembrance purposes at http://www.culture24.org.uk/asset_arena/5/55/15555/v0_master.jpg

Cartogram Map
A cartogram map is when some variable is substituted for land size. This map shows the world in reference to population. As you can see China and India have more population than other countries, so they appear larger. Take a look at the size of Indonesia compared to Australia, weird! I found this map at http://strangemaps.files.wordpress.com/2007/03/population1024x512.png
Flow Map
Flow maps conbine information and have less clutter than most maps. They also show the movement of things over a given time.

Isoline maps are a two-dimensional map representing a three-dimensional model. They have continuous lines joining points of the same value. This map shows the elevation of New York state. I found this map at http://www.regentsprep.org/Regents/earthsci/graphics/102A_9-10.gif
Proportional Circle Map
Proportional Circle maps display data in relation to the siz of circles. This map shows the American Indian population in the states out west in the United States. I found this map at http://www.neiu.edu/~nerobert/Circle%20Map.jpg
Choropleth Map
Choropleth maps are maps that are shaded or patterned in proportion to the measurement variable being displayed. This map shows domestic freshwater use in the United States in 1990 by millions of gallons used per day... Florida's not looking so great... I found this map here http://water.usgs.gov/watuse/graphics/domap.st2.color.gif
Dot Distribution Maps
The dot distribution map portrays quantitative data as a dot. They are very useful in portraying populations, like seen in this map of the United States in 2000. I found this map here http://www.census.gov/geo/www/mapGallery/images/small2kden.jpg
Propaganda Maps
Propaganda maps are used to skew the opinions of their readers into believing whatever the creater is trying to portray. This map was published in Germany in 1934 to create fear of Czech bombing. I found this map at http://strangemaps.files.wordpress.com/2006/12/threat.jpg
Hypsometric Map
A hypsometric map is a map that depicts the configurations of land. This map is an antique map of the United States showing elevation by shading. I found this map at https://www.rare-maps.com/maps_pic/JOC-1896-HYPSO.jpg

A PLSS map is a PublicLand Survey System that subdivides and describes land in the United States. This map shows a portion of Minnesota's PLSS Map, as you can see the state of Minnesota is marked off into sections and townships. I found this map at http://www.fairview-industries.com/standardmodule/mn-exmp2.gif
Cadastral Map
A cadastral map is a comprehensive register of the land bounds of a county. It usually includes ownership and dimensions of land. This one I found is of counties in Delaware. I found this map at http://www.dalisproject.org/images/cadastral_map.jpg
Thematic Map
Thematic maps are made to reflect a particular theme about a geographic area. This map represents the Land Reserves in Hawaii and who owns the land. I found this map at http://www.creativemappingsolutions.com/maps/thematic/thematic_map_1-web.jpg
