Population Profile


This is a population profile of the United Kingdom. It is an analysis of the male and female population in various age ranges. This information would be useful to the Census Bureau when looking at funding for social programs.

Scatterplot


This scatter plot graph is quick and easily designed by plotting multivariate values that share a common association or correlation on a graph free handed. As seen in this scatter plot the years of experience a person has will ultimately affect their income.

Index Value Plot

The index value plot graphs condition of sites being monitored from 1988 until 1993 for changes in vegetation area in sampled woodland sites. Index value plots are useful when showing change over time.

Accumulative Line Graph

This is an example of the Lorenz curve or an Accumulative line graph meaning the overall probability of two scenarios distributed on a graph. These distributions can be infinite but will always start at 0 but are invariant .

Bilateral Graph

This particular bilateral graph shows positive and negative values for two variables global corporate governance versus the nations wealth in 3rd world countries in 2002. The strong the corporate governance the stronger the nations wealth.

Nominal Area Choropleth Map


Also known as a descriptive map this nominal area choropleth map provides geographical information about Canada's vegetation. The variation in color is associated with qualitative differences.

Standardized Choropleth Map

Even though the legend is unclear this is a standardized choropleth map by normalizing raw data in other terms, providing percentage information of the total population of Canada residents that are 14 years old and under during the 2006 census.

Bivariate Choropleth Map



The side by side compasion map represent two sets of spatial data, the correlation between land use and life expentancy in Africa, on one map with nominal data and an interactive use of color.

Unclassed Choropleth Maps



This is an example of an unclassed choropleth map it is hard to interpret between the classes it represents due to the use of monotone coloring and shading.

Classed Choropleth Maps


As with most classes choropleth maps it is easy to interpret this map, with very few colors being used it is less confusing to distinguish between the different data attribution classifications being displayed.

Continously Variable Proportional Circle Map

In a continously variable proportional circle map the size of the symbols will vary due to the direct value of the data it represents. The bigger the circle the more value it holds.

DOQQ


DOQQ also known as Diqital Orthophoto Quarter Quandrangles is one quarter of a digital angle that is displaced by the camera angle in which the terrain has been removed at a scale of 1:12,000.

DEM

Also known as Digital Elevation Model, DEM's are simple regularly spaced elevations of various ground positions. The normal scale is 1:250,000 and is based on latitude and longitude locations.

DLG

Also known as Digital Line Graph, DLG's are digital representations of cartographic information in large, medium, or small scales derived from ditigal vectors of other maps.

Isotachs

The wavy lines on this map is known as isotachs, these are needed to determine wind speeds along with isobars which are recorded in kilometers per hour.

Isobars

The curvy lines in this image are known as Isobars, which depict pressure gradients of an area. The isobars in this photo are fair close which indicates a steep pressure system moving through.

LIDAR

This process is known as LIDAR, in simple terms an elevation map. The information obtained using the LIDAR technique is merely reflection data using a laser beam to obtain elevation differences, which is useful in determining topographic changes.

Doppler Radar


This is an image enhanced radar derived data product obtained over a period of time using the doppler effect to diagnose the weather of a given area.

Black and White Aerial photo

Also known as orthophoto, this black and white aerial high altitude images provide great detail of the area. From this high view once can see the differences in terrain relief which can be very useful when it comes to updating surface features on maps.

Infrared Aerial Map

This photo is a "sky" view using infrared aerial mapping, which is most useful for planning Agriculture. Different color tones have different meanings for instance, this shot contains mostly live vegetation which is denoted in red. The green coloring denotes dead vegetation, whereas the blue represents ground and can vary in color depending on the moisture content it holds.

Cartographic Animation



This is an example of cartographic animation it is real time animation that changes as the event changes. These maps are user defined and the information generated is a result of what is questioned, in the case it is cancer deaths in Nebraska County.

Statistical Map


"Statistical map of Napoleon’s Russian campaign of 1812 ", the map provides the temperature pattern experienced during August - October. As well as a statistic count of soldiers and their advancement or retreat.

Cartograms

I would love to tell you what this cartograms represents but I can't because it is in Spanish. What I can tell you is that is picture represent the same statistical data but at different valuations, hence the enlarged shapes. Cartograms are based upon size depictions but the positioning and approximately scales are as close as possible to the original.
