standardized choropleth

This standardized choropleth map shows one variable.  It shows the distribution of the worlds population per square kilometer.

continuously variable proportional circle map


This is a continuously variable proportional circle map.  The map is of the known craters on the Earths surface. The size of the circles are proportional to the actual size of the craters.

correlation matrix


A correlation matrix is a type of graph that allows you to compare two different things in a number of categories.  

univariate choropleth map


A Univariate choropleth map is a choropleth map that only shows one variable.  In this map it shows the percent of Pacific islanders living in Auckland, New Zealand.

bivariate choropleth


A bivariate choropleth map is a variation of a normal choropleth map.  It shows two different variables.  In this map it shows the population and the median home value.  It is interesting to see the home values in the more or less populated areas.  

DOQQ


A DOQQ map is  an aerial picture that is geometrically correct.  The scale is correct and you can use the  map to measure distance.  in this map the scale is correct and would be a good map to use to see how far something's true distance is.

dem map

A DEM map is a map that shows a 3-D representation of the Earth's surface.  This is a DEM map of Lake Tahoe from the USGS.  You can see where the lake is in the the center and see the much taller mountains surrounding it.

cartographic animation


This is a map of the 2004 Indonesian Tsunami.  The map uses an animation to show where it started and where it went.

choropleth map


A choropleth map is a map that has a theme and uses colors or shades to show the measurment of what is being mapped,  the theme.  In this case the theme is of population in Europe.

stem and leaf plot


A stem and leaf plot is a statistical way to show quantitative data.  In this plot it is showing the ages of people at a family reunion.  The ages range from 1 to 81

nominal choropleth map


A nominal choropleth map is a map that displays nominal data.  In this map it is showing the percentage of black condo owners in california.  

similarity matrix

Similarity Matrix map looks crazy, but it allows us to compare the similarities between two different things.  

range graded proportional circle map


A range graded proportional circle map is a circle map where the data is categorized into ranges.  This map is an old circle map of France

scatter plot


A scatter plot shows the two variables for a set of data.  This scatter plot is comparing the age of wives to husbands

star plot


A star map uses different designs to show different variables in a set.  This star plot is showing the differences

index value plot

\

Index value plots show current trends and also let you compare them to past trends.  This map is showing recessions in the USA.  And it shows you the border between recession and not.

lorenz curve


A lorenz curve is used in economics mostly.  And it just compares people who are under the average in distribution of income.

unclassed choropleth map

In this unclassed choropleth map it is showing the difference in population change.  There are small differences in the keys from classed choropleth.

classed choropleth map


A classed choropleth map is a map that uses data already collected and aggregates it.  In this map it is comparing the ratio of women to men across the USA

triangular plot


A triangular plot, is  a graph shaped like a triangle.  The triangle shows the composition of something consisting of three variables all adding up and completing the triangle.  In this example you can see the make up of the triangle.  

bilateral graph


A bilateral graph is a type of bar graph that has many bars comparing different data.  In this example you can see the amount of trade in different categories like exports or imports.  

boxplot



A boxplot is a graph that shows groups of numerical data.  In this example you can see the three different groups.  The boxplot is depicting lottery payouts and you can see as the years progress the payouts become smaller and closer to the median.

parallel coordinate graph


A parallel coordinate graph is a tool used to simplify multi dimensional graphs.    And the lines show where they are and in which dimension.

histogram



Histograms show data, they show the spread of the data, if there are any outliers, and it shows the average data and which occurred most.  This map is just a simple example of that.  We can see that in between 299.8 and 300 was the most frequent data

isotach map


The isotachs on this map show areas with corresponding wind speed.  on maps like this, you can see many different isotype lines completing a weather map.

statistical map


A statistical map is a map where a variable such as rainfall or population is shown.  In this map the average commute is shown by state.

black and white aerial photo

http://www.jaha.org/edu/flood/rebuild/img/panoramas/index.html


A black and white aerial photo is taken from high above to get an aerial view over a wide range.  It is used to get information on a big area that is not easy to obtain from the ground.

isoline map


This isoline map is showing precipitation in Washington State.  The isolines link areas that have the same amount of precipitation.  Closest to the coast and east of the mountains  has the most because of orographic effect.  

dot distribution map


This is a dot distribution map that each dot represents population around lake St. Clair.  This particular map was showing the effects of population on the lake.

topographic map

http://mail.colonial.net/~hkaiter/topographic_maps.html


A topographic map is a map that shows relief features such as elevation, using contour lines.  As you can see in this map  the contour lines are representing different elevations.

cadastral map




A cadastral map is a map that shows how land is parceled out according to ownership.  This is a simple cadastral map that shows land parceled out along the Georgia coast.  Sometimes these maps can go into more detail.

planimetric map


A planimetric map is a map that shows only the horizontal positioning of things and does not take elevation into account.  As you can see this map just shows a street with businesses on it and pays no attention to elevation.

mental map


This is a mental map that I created showing the route that I take from my home in Fort Lauderdale to my apartment in Tallahassee.  These are the driving directions and show my preference of roads to take.

plss map



The Public Land Survey System was a system used to survey and divide land .  The system was started a little bit after the American Revolution and made it easier for the "country of Yeoman farmers" 1. to head out west.  This is a map of ohio being parceled out.

hyposemetric map



This is a hyposemetric map of France.  A hyposemetric map shows different elevation using colors and other variables.  In this map you can see the sea, and then going inland the elevation rises.

flow map

http://www.groundwatersoftware.com/map_viewer.htm


This flow map tracks cases of west nile virus across the USA.  The different colors represent how far the state is from the Mississippi river and the  height is proportional to confirmed cases of west nile

proportional circle map


This circle map shows the american indian population of Western States in America.  The circles are proportional to a range of numbers representing population.

wind rose map

http://www.mathworks.com/matlabcentral/fileexchange/17748-windrose


This is just your simple wind rose map.  These maps show from what direction wind is coming and also at what speed.  They were used before compasses were invented at let people know what direction certain places were located relative to a set location.

isopleth map



This isopleth map shows the number of deaths by the h1n1 virus, or swine flu.  The different lines and different colors mark the areas the number of deaths that occurred there.

cartogram

http://www-personal.umich.edu/~mejn/cartograms/


This cartogram shows a map of the world.  It looks a bit funny doesn't it?  That is because each country is proportioned to reflect the GDP it puts out every year.  You can see the United States are very large as is Japan, but you can barely see Africa
