Stem and Leaf Plots

Stem and leaf plots use data sets and put the first number in the first column and following numbers in the second column. This is a good way to also see the frequency among the data set. In this one, we see that income in the 300's is way more frequent than that of the 600s.

Box Plots


Box plots use data sets to show how particular sets of data within that group compare. In this one, it compares 3 machines and energy produced. Machine 3 was the highest, while 4 was the lowest.

Scatterplot

Scatterplots use two separate variables and graph them on an (X,Y) scale. The statistics are noted and the closer the dots are, the higher the correlation. This one shows women and men alcohol related deaths.

Index Value Plot


Index value plots are a good representation of statistics over time. This map shows streamflow over 10 years in the United States. The flow stays fairly balanced throughout that time span.

Lorenz Curve


The Lorenz curve takes into account the way things should be statistically compared to the way things actually are. This map is an example and it shows the income distribution for the population of Americans.

Classed Choropleth Maps

Classed choropleth maps use shading and a legend to show statistics across an area. This one in particular shows the cost:expenditure for public education throughout America.

Range Graded Proportional Circle Map

These maps use circles and widths of the circles to show the range of data across a region/area. This map shows channel width. The larger circles represent wider areas, while the smaller ones represent the smaller areas.

Continuous Variable Proportional Circle Maps

These maps use circles and sizes of the circles to represent certain attributes across a certain area. This map shows the Mexican population in western America.

DOQQ Maps

DOQQ maps use aerial photography to show land in infrared or red/blue color infrared format. This particular map shows Lake Travis in Texas in Red imaging.

DEM Maps

DEM maps are digital elevation maps. They use digital imagery to show elevation of land. This is a DEM of Borneo.

DLG Maps

Digital line graphs are also provided by the USGS and use digital lines to portray land. This is a map of the northern quadrant of San Francisco. 

DRG Maps

DRG maps are scanned images from the US Geological Service. This is one from Michigan. 

Isopleth Maps

Isopleth maps use 3D imaging to often show elevation of a certain regions. There are other uses for the map. However, this is the most popular. This is a map of a mountain region in Antarctica.


Isopach Maps

Isopach maps use contour lines to show thickness within a tabular unit or area. This map is a bit dated, but shows the thickness of the English channel basins. It does not necessarily mean deeper water, however it has increased subsidence, as noted on the maps footnote.

Isohyet Maps

Isohyet maps use contour lines to show areas of equal precipitation.  In this map, Taranaki, a region of New Zealand is shown. The smallest circle resemble the area of the highest precipitation.

Isotach Map

Isotach maps use lines to show wind pressure in weather reports. Here we see a map of the US and wind pressure and currents.

Doppler Radar

Doppler radars are used by virtually every weather company in America. They show intensity and direction of the weather that is being predicted to come. This is a doppler radar from Florida in 2004.

Black and White Aerial Photo

Black and white aerial photos are often used by military personnel. This photo was actually taken from an SR-71 jet in the 80's.

Infrared Aerial Photo

These maps/photos display an overhead photo of something, often in negative format. This is an aerial photo showing the leaves changing in the fall.

Cartographic Animation

These maps often use color coded and 3d imaging to show a certain attribute about a particular area. In this map we see the effects of Mt. St Helens.

Statistical Map

Statistical maps use color coded or numerical displays to show a distribution of a certain statistic over an area. We often see stats like rainfall or precipitation in these maps. This, for example, is a map conveying the precipitation across the USA.

Cartograms

Cartograms are a color coded representation of a certain area's distribution in certain categories. This shows the division of republican and democratic voters in America for the 2004 election.

Flow Maps

Flow maps show the direction, or flow, of how things come about. A series of events or cause effect, so to speak. This is a flow map/chart of the Gators offense last season and how it was so unorganized.

Isoline Maps

Isoline maps use continuous lines that represent the same statistic or attribute of a certain area. This one shows the air pressure across America.

Proportional Circle Maps

Proportional circle maps use circles of differentiating sizes to show the intesity or density of certain areas bases upon certain statistics. Here is a map that shows the voting patterns across the USA for Obama/McCain supporters. We see more red dots, but the blue dots are a lot bigger, hence why Obama won.

Choropleth Maps

Choropleth maps use shading and color coding to indicate differences or similarities within a certain area. The above map shows the different climates across America. As we see, it uses color coding to show the differences.

Dot Distribution Map

Dot distribution maps use dots spread throughout the map that notify a particular feature. In this case, the map above displays earthquake activity across the world. The dots indicate the location and intensity of the earthquakes.

Propaganda Maps

Propaganda maps are similar to mental maps, as they are a depiction of the world or a place by a particular person. Typically used in a satirical sense. Here we see a map of the world through the eyes or Reagan. This shows how the world was viewed as if USA and USSR were the only places that mattered at the time.


Hypsometric Maps

A hypsometric map shows elevation by either shading or contour lines. This is a map of Canada, where you can see the Rockies are extending up through the western part of the country, as indicated by the shading.

PLSS Maps

PLSS maps, or Public Land Survey System, divide areas up into a rectangular grid to show public land that's owned by the federal government. This right here is a map of a portion of Utah.

Cadastral Map

Cadastral maps show boundaries or territories in a specific area. They are often used for neighborhood planning. This one appears to be community map that shows all the lots for houses and other buildings.

Thematic Map

Thematic maps are used to convey a particular area and how that area may have differentiating attributes. This map, for instance, shows how arid the land across America is. As you see, Florida has very moist soil, while practically all of Nevada has very dry soil.

Topographic Map

Topographic maps are a lot like planimetric maps, but will take into affect elevation. This map is a depiction of Romania that shows elevation by using different colors. Green displays lower elevation while the darker brown represents higher elevation.

Planimetric Map

Planimetric maps are maps that will show an overhead view of a particular area. It won't take into affect elevation or any other natural elements. This one shows what looks like a city planning project. 

Mental Map

Mental maps are a depiction of how the world is seen through ones eyes. This one is an image of how a thriving Chinese economy views the economic struggle of America.
