nominal area choropleth map
This is a choropleth map using nominal data (different classes) showing the percentage of Latino/Hispanic citizens in Florida counties.
DOQQ
DOQQ (digital ortho quarter quads) are aerial photos that have been corrected so that the pixels are aligned with longitude and latitude lines, and have a narrowly defined region of coverage. This DOQQ image is of Louisiana.
similarity matrix
http://tomcat.esat.kuleuven.be/txtgate/tutorial.jsp
A similarity matrix is a matrix of scores which express the similarity between two data points. Most of this matrix is, indeed, similar except the bottom right hand corner.
correlation matrix
http://www.investors-routemap.co.uk/Guidebook_price_correlation.htm
A Correlation matrix describes correlation among variables. It is a square symmetrical matrix. The one shown is from an investment website showing the correlation between bonds and markets. The higher numbers are color coded in reds and oranges as "dangers".
star plot
http://start1.jpl.nasa.gov/caseStudies/autoTool.cfmA star plot consists of a sequence of "spokes" (radii). Each spoke represents a different variable in the multivariate data set. The star plot I chose maps out the designs for the NASA space systems. Each colored line represents a different design method they used.
Parallel Coordinate Graph
A Parallel Coordinate Graph can be a little tricky to read. The up and down slopes of the lines indicates change through time from one value to the next. The lines in parallel coordinate displays don't indicate change. Instead, a single line in a parallel coordinates graph connects a series of values - each associated with a different variable - that measure multiple aspects of something.
portolan chart
http://pro.corbis.com/search/Enlargement.aspx?CID=isg&mediauid=DAAC78FA-5E2E-4FA6-BEB5-0A01656FB9CC
A portolan chart is an early modern European navigation chart, dating from the 13th century or later. This one is of Italy and Greece.
lorenz curve
http://www.divisionoflabour.com/archives/cat_misc.php
Originally developed for representing income distribution, the Lorenz curve usually shows percent of households vs the percent of income. The Lorenz curve is shown in red, while the "perfect equality" is shown in blue.
index value plot
http://www.galatime.com/2006/03/05/nifty-volatility-atr-at-historic-lows/Index Value Plots are mostly found in the financial business atomospheres. This one is for the stock Nifty close ranging from the years 1995-2006 (yellow). The blue line represents the 14 day Average True Range.
triangular plot
A triangular plot is a map charting three variables with a constant sum. This triangular plot shows soil composition from the US Dept of Agriculture. One side represents sand, one side silt, and one side clay. Each side has a number scale for the variable composition.
bilateral graph
A bitlateral graph is a chart/map that shows data through two (sometimes more) related variables. This map shows two variables- one 30 yr fixed mortgage (blue) and one 30 yr fixed jumbo mortgage (green).

cartographic animation
(This image is only animated when you go to the link found below)A cartographic animation is a hands-on animated map. Usually found online, you can usually click or roll your mouse over the map to animate the specific item.
This choropleth map shows Nebraska County and it's deaths by certain diseases (classed and unclassed data) in 1996. Scrolling over the key shows a change in different types of diseases on the map.
DEM
http://www.soest.hawaii.edu/coasts/data/oahu/dem.htmlDigital Elevation Models (DEMs) use a raster grid that determine topographic elevation for a specific area.
This map shows the elevation of Hawaii's island - Oahu.
isobar
http://www.csulb.edu/~rodrigue/geog140/lectures/pressure.html
An isobar is a contour line of equal or constant pressure in meteorology. This is a map of isobars of pressure in New Zealand.
doppler radar
Doppler Radar uses pulses of microwave radiation to locate different types of precipitation in it's vicinity. I chose this doppler radar image because it was a hurricane in Florida that I personally experienced- Hurricane Charley in 2004.
statistical map
http://www.cviog.uga.edu/Projects/gainfo/gastat.htmA statistical map shows a set of data (or statistics) for a specific area. This map shows the population change in the US per state from 1990-2000. The highest population change was in Nevada (66%) and the lowest was in D.C. going down 5.7%. The average US population rate went up 13%.

isohyet
http://www.environment.gov.au/soe/2001/publications/technical/wind-erosion/index.html
An isohyet is a type of isoline that shows the precipitation in a specific area. This map shows the isohyets in Australia (lines only... the colors represent the Dust Storm Index)
proportional circle map
http://www.statcan.ca/english/Estat/guide/map-mul.htm
A proportional circle map shows numerical data through a circle, usually the bigger the circle- the bigger the number. For instance, this map shows the population of Canada through the size of the circles. Each circle is located in the area where the most population is located in each province... the bigger the circle, the larger the population.
isotachs
www.srh.noaa.gov/.../GEMPAK_Q-vectors.htmlIsotachs are a type of isoline that determine the wind speed. The vectors show direction. This map has green isotachs around the state of Florida.
LIDAR
Light Detection and Ranging (LIDAR) is a form of remote sensing that uses scattered light to find range and detect through lasers. This image is of Manhattan... taking right after the 9/11 terrorist attacks and show the rubble of the World Trade Center towers.
stem and leaf plot
A stem and leaf plot is an organizational way of mapping numerical data. The stem is the common digit at the beginning of the numbers and the leaf(s) is/are the ending digit(s).
For instance, this stem and leaf plot displays the ages at a family reunion. The first row shows 01, 08, 09 or 1, 8, 9. The second row shows 32, 34, 37, and so on.
PLSS map
PLSS maps come from the use of the Public Land Survey System. These rectangular land plots were divided up to let Public Domain Land benefit US citizens. This map shows Public Land in Minnesota.
population profile
Population profiles are a type of map that chart out the age vs the population in a specific location. A lot of the time they are split to show female population and male population separately. The profile I chose shows the amount of people in Botswana with AIDS projected for the year 2020.

isoline maps
http://www.lib.utexas.edu/maps/atlas_mexico/mean_annual_precipitaion.jpg
An isoline map has lines (or curves) that connect two points with the same value. This map shows the annual rainfall precipitation for Mexico. You can see the connection between the rainfall and the mountainous areas.
cartograms
http://images.google.com/imgres?imgurl=http://issrweb.asu.edu/images/gis/cartogram.gif&imgrefurl=http://issrweb.asu.edu/services/gis/sample-maps.html&h=416&w=660&sz=107&hl=en&start=26&sig2=fB2frQdQYVrzjawf4s0Tsg&um=1&tbnid=vh6gsgy3HDAPKM:&tbnh=87&tbnw=138&ei=6GOXSJOlDJSypgTT4PXmBg&prev=/images%3Fq%3Dcartograms%26start%3D18%26ndsp%3D18%26um%3D1%26hl%3Den%26rls%3Dcom.microsoft:en-us:IE-SearchBox%26rlz%3D1I7SUNA%26sa%3DN
I think cartograms are really cool. They show a distorted view to show the information on the map. The one I found shows the population per county in the United States. The bigger areas shown are the denser metro areas (Florida, New York, and California).

aerial photo (black and white)
This is an aerial (overhead) black and white photography of an area in Delaware County, Pennsylvania. I found the website pretty interesting because they had the same aerial view photographed once in 1960 and then again 40 years later, in 2000. I used the most recent photo, taken in 2000.
cadastral map

hypsometric map
Hypsometric maps use different colors to represent the elevation of terrain on a land area- green meaning flat, reddish/brown meaning hilly/mountainous, and white at highest peak.
thematic map
"thematic map" meaning themed map, basically. Just a map with a specific purpose, used with various different map types. This one shows the Hispanic population by county in Texas shaded by colors.

A windrose plot is a circular graph with each spoke broken down into color-coded bands that show wind speed ranges. They also use cardinal directions to show what speed wind was in what direction.
This map shows winds average over the period September 11-13, 2001 for the NYC area (coming from the west).
scatterplot
http://www.japanreview.net/images/Jittered%20Scatter%20Plot.gif
A scatterplot uses points on, usually, a graph to explain it's coordinate.
This scatterplot I found actually shows two different views on the worlds population GDP per capita in US dollars. The 1 on the x-axis represents "jus solis" which means citizenship by birth and countries with birth rights. The 2 represents not a citizen by birth. Each point represents one country's average GDP per capita (for each column).
propaganda map

A propaganda map is used to "sway" the viewer to think one thing over another. A lot of propaganda maps are used politically.
This map uses plastic cups on a platform shaped like the US to describe the American obesity rate across the country. Each color inside the cup represents the area's obesity statistic. This map uses propaganda by shaping the McDonalds golden arches in the middle to show that McDonalds is partially to blame for America's obesity.
As I was researching more about this famous propaganda map, I found this: "Figures from 1994 are indicated on one side of the cups, and those from 2002 on the other, so that the extraordinary increase in obesity levels becomes dramatically apparent as viewers walk from left to right." I found that to be very interesting.
mental maps
http://images.google.com/imgres?imgurl=http://www.peterminnema.nl/img/legends/identity_grift.jpg&imgrefurl=http://www.peterminnema.nl/legends.html&h=500&w=500&sz=174&hl=en&start=37&um=1&tbnid=-6msLe6Czud24M:&tbnh=130&tbnw=130&prev=/images%3Fq%3Dmental%2Bmaps%26start%3D20%26ndsp%3D20%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DN
I think mental maps are very eccentric. They can describe so many different things, places, emotions, etc. You don't necessarily need a legend, you can use your imagination or inner senses to describe the map. This map, for instance, is describing the layout of a park possibly in the middle of a city? Each picture represents a different area of the park. In the top right corner, there is most likely a skate ramp or a skateboarding area. There are probably statues in the central area and basketball hoops in the southeast corner.

flow map
This map shows the JetBlue Airline flights from their main hubs (NYC and Long Beach, CA) to other cities in the United States (and San Juan). The orange lines indicate roundtrip flights available starting in May and June 2008.
box plot
This box plot data explains the age ranges of adults and their blood pressure. The middle line in the box plot for the age range 30-45 shows that the median blood pressure for people of that age is approx 145. The outlines of the box show the next highest and lowest percentiles (25% and 75%)... reading at 141 and 155. The horizontal lines extending out portray the 10th and 90th percentile at 125 and 170. The two dots on the right hand side are values greater than the 90th percentile- 175 and 177.

topographic map
This topographic map illustrates a community located along a shoreline. Topographic maps show elevations of the land's surface (in feet above sea level) through the use of contour lines (these are the brown lines on this map). They trace points of equal elevation across the map, just like the one labeled "30" closest to the shore, as well as "50" found right behind it.
