Windroses show windspeeds and the directions they are blowing in. This one is of Olympia, Washington in 2000. http://www.climate.washington.edu/windrose/Seattle-WindRose.jpg

Climograph

Climographs show precipitation and temperatures for a specific place over a period of time. This one is for Memphis, TN for a year and shows us that they reached their peak temperature in July and had the most precipiation in January. http://www.uwsp.edu/geo/faculty/ritter/images/atmosphere/climate/climographs/memphis.jpg

Population profile

This is a population profile that is pridicting figures. It is showing the predicted amount of men and women with and without aids by age. http://www.ifad.org/operations/regional/pf/figure1.gif

Scatterplot

This scatter plot has husband's age on one axis and wife's age on the other. It shows a positive correlation between the two, meaning as a husband's age goes up so does the wife's.

Index value plot

This is a prime example of an index value plot. It shows us the average streamflow index from since June 1999. This shows us if it has been exceptionally dry or wet. http://water.usgs.gov/waterwatch/regplots/real/real_us_2.gif

Lorenz Curve

This lorenz curve shows the income distribution in households. The percentage of households is plotted on one axis and the percentage of income on the other. http://www.sarpn.org.za/documents/d0000990/images/lorenz_curve.gif

Unstandardized Choropleth

Unstandardized choropleth maps like this one show unordered and unaveraged data that have no rankings. This one shows minority goups with the highest populations in the states. https://courseware.e-education.psu.edu/courses/geog482/graphics/citationexample.jpg

Standardized choropleth maps

This map shows the population density of the US according to the 2000 census. It is measured by population per square mile by state. http://upload.wikimedia.org/wikipedia/commons/thumb/7/78/USA_states_population_density_map.PNG/800px-USA_states_population_density_map.PNG

Univariate Choropleth

Univariate Choropleth maps only show one piece of data unlike the bivariate ones. This particular map shows the percent of indivduals who live in poverty in the US. http://www.cdc.gov/pcd/issues/2007/oct/images/07_0091_02.gif

Bivariate choropleth maps

This is a good example of a bivariate choropleth map. It shows two different pieces of data, population density in 2002 and percentage population change between the years of 1989-2002 of Russia.

Unclasses Choropleth

This unclassed Choropleth map shows acres of vegetables harvested in the United States in 2002.

Classed choropleth maps

Range graded proportional circle map

These maps use circles to show an amount of something. For example this map shows population of cities in the Great Lakes area and the larger the circles, the greater the population. http://mapmaker.rutgers.edu/355/dotProporCircle.jpg

Continuously variable proportional circle map

This is a map of West Germany that shows the major industries different cities. The map uses circles to show data and the size of the circle is in relation to the amount of data.

DOQQ

A digital orthophoto quartar quadrangles is a computer generated image of an ariel photograph. These are used to fix the displacement caused by camera tilits. http://www.pasda.psu.edu/tutorials/arcgis/images/doqq.jpg

DEM

DEM is a digital elevation model or a representation of a ground surface topography. http://edc.usgs.gov/images/dem.jpg

DLG

DLG stands for digital line graph and these are digital vector representations of cartographic information. This one here shows the Lake Tahoe Basin.

DRG

DRG stands for digital raster graphics. These are scanned pictures of the United States Geological Survey like the one shown here.

Isopach

Isopachs are lines on a map that connect areas that have geological structures with equal thickness.

Isohyets

Isohyets are lines on a map that connect points that have equal rainfall. The map here shows rainfall measured in millilitters.

Isotachs

Isotachs are lines on a map that connect points with equal wind speeds. The map here shows wind speeds over the eastern United States.

Isobars

This map shows a low pressure cell. An isobar is a line that connects points of equal pressure.

LIDAR

LIDAR stands for light detection and ranging. It measures scattered light and creates a 3D model like the one shown here.

Doppler Radar

A doppler radar is simply a radar that uses the doppler effect. This is done by bouncing echoes off of targets to measure their radial velocity. This is a doppler radar of a hurricane over Florida.

Infrared aerial photo

Infrared aerial photo uses different light spectrums to show many things like changes in the environment like in this picture here. http://www.aerialarchives.com/imagedb/IR0010154f.jpg

Cartographic animations

A cartographic animation map moves in some way. The movement's purpose is to show something happening over a period of time. For example in this map is showing the coast flooding as the water levels rise.

Statistical maps

Statistical maps show quantity and location of statistic data at the same time. This map shows corn farms and each dot represents 10,000 acres. http://cache.eb.com/eb/image?id=64892&rendTypeId=4

Cartograms

Cartograms are maps in which area is distorted. Like in this map of the US, the states are not displayed in the correct size instead they are shown according to the population of the counties. http://upload.wikimedia.org/wikipedia/en/4/47/Cartlinearlarge.png

Flow maps

Flow maps use lines to show movement. The thicker the line the more that is being moved and vise versa. This map is showing international telephone traffic. http://www.mundi.net/maps/maps_014/august2000_small.gif

Isoline maps

An isoline map liek the one shown is a 2D representation of something 3D. In the example here the map is showing a peak and a crater. http://www.sfei.org/ecoatlas/GIS/MapInterpretation/images/fig219.gif

Proportional circle maps

A proportional circle map uses circles to show data. For example, in this map shows internet use in Europe and the larger the circle the more people that use the internet and smaller the circle the less the people that use the internet.http://www.geog.ucsb.edu/~jeff/gis/proportional_symbols_files/map2.jpg

Choropleth maps

Choropleth maps are another one that use colors or shades to show proportions in information. My example shows the proportion of males per 100 females in the United States according to the 2000 Census.

Dot distribution maps

Dot distribution maps are most commonly used to show population, like in the example I used which shows the 2000 population of the US. The maps use dots to show information. When trying to show population, the more dots in the area, the more people that live there.

Propaganda maps

Here is an example of a propaganda map that is comparing infant mortality rates. A propaganda maps are directed at a specific audience and are designed to influence them to think a certain way. The information they give in the maps may or may not be true.

Hypsometric maps

This is an example of a Hypsometric maps that shows the average annual precipitation for the state of Arizona. Hypsometric maps use colors or shading and a scale to show information. http://www.ocs.orst.edu/pub/maps/Precipitation/Total/States/AZ/az.gif

PLSS maps

Here is a PLSS ( public land survey system) map that shows the townships of Alabama. These maps are used to divide land owned by the government up. http://www.rootsweb.ancestry.com/~alfrankl/plss_basemap_alabama.jpg

Cadastral maps

This is a cadastral map of the village of Pielnia. These maps show land boundaries and who owns them. http://upload.wikimedia.org/wikipedia/en/c/c9/Pielnia_1852.jpg

Thematic map

A thermatic map shows geographic patterns by using statistical data, such as income or like in my example population. The maps also use a color coded key. My example shows the population changes in the United states from 1990- 1996. http://www.sou.edu/Geography/JONES/GEOG280/stpop96.GIF

Topographic map

A tophographic map most commonly uses contour lines and shows natural and man-made features on it. The example I chose shows Stowe, Vermont and it uses 20 foot contour intervals and the scale is 1:24,000. http://upload.wikimedia.org/wikipedia/commons/thumb/7/79/Topographic_map_example.png/350px-Topographic_map_example.png
