Doppler Radar

Doppler technology utilizes microwaves to track direction and speed of suspended water droplets in the atmosphere. NOAA created this map to show the eye of Hurricane Claudette in Houston, Texas.

Infrared Aerial Photo

http://ecosystems.mbl.edu/pie/data/MAP/irparker.jpg

Infrared Aerial Photography is a powerful tool that can be used to document changes to the environment, the health of forests, wetlands, bays and oceans, as well as many other applications.

Red tones in color infrared aerial photographs are almost always associated with live vegetation and the tone of red can be a guide to the density and health of the vegetation and how vigorously it is growing. Dead vegetation will tend to appear as various shades of tan or green. Thus infrared imagery is particularly useful for crop, forest, wetland, vineyard and other agricultural analyses.

Color infrared aerial photography is also useful for analyzing water depth and sediment content. Clear, clean water will appear very dark, close to a black tone. As sediment content increases the shades shift to blue color tones. Color tones of very shallow water may reflect predominantly the color tones of the soil beneath this water. Color infrared aerial photography is therefore uniquely useful for analyzing sediment flows.

In the infrared aerial photo above, which depicts the mouth of the Parker River in Massachusetts, you can see that the water appears to be clean and clear, since it takes on such a dark, blackish tone. Also, it is evident from the photograph that there is a great deal of vegetation at the mouth of this river, with the more dense areas of vegetation appearing as bright red.

Black and White Aerial Photo

Aerial photography is the taking of photographs of the ground from an elevated position. The term usually refers to images in which the camera is not supported by a ground-based structure.

Black and White Aerials can show the evolution of site conditions over time, as illustrated through aerial photos 

Statistical Maps

Statistical maps are used to display the distribution of some variable over a specified geographic area, usually defined by political boundaries. The map below is an example of a statistical map. This map shows the distribution of the Internet, across the globe.

Cartogram

A Cartogram varies the size of geographic areas based on the data values associated with each area. Cartograms scale geographic areas to things such as population, GNP, and electoral votes.

This map is a population cartogram of the world. Asia is larger in comparison to the rest of the world's population.

Flow Maps

Flow maps are used to show the movement of objects from one location to another. They are easier to read many times because of the merged edges. They are used frequently when depicting migrations.

This map shows the flow of Texas truck freight.

Isoline Map

An isoline map conveys numerical values for continuous distributions by means of lines joining points of equal value.

The weather channel uses this map in order to display temperature differences.

Proportional Circle Maps

Proportional circle maps display data in relation to the size of the circles. These proportional circle maps illustrate the distribution of four mineral deposits in the Selwyn Basin of Canada using circles that are sized according to the quantity of mineral found at that location.

Chloropleth Map

Choropleth Maps are thematic maps that are based on predefined aerial units.  These maps use graded color series to show least intensity to most intense (shown using a light to dark color pattern).

This particular map shows the population densities of the countries of the world http://atschool.eduweb.co.uk/kingworc/departments/geography/asgraphmapskills.htm

Dot Distribution Map

Dots distribution maps use visual imagery to illustrate the quantity of a particular variable by showing the distribution of that variable over a given geographical location.

This dot distribution illustrates the distribution of the world's population and can be found at  http://www.museumstuff.com/learn/topics/Dot_Distribution_Maps

Propaganda Map

http://bigthink.com/ideas/21097

A propaganda map is used for the intent of threat, an agent of control, exploitation, manipulate and or emphasize. The propaganda overall, is a tool for power.

This particular propaganda map was used by the United Kingdom to show what Germany's secret goals were to taking over Europe. This was a way to get all the people of surrounding countries that were threatened by this portrayal

Hypsometric Map

This hypsometric map shows the relief of the surface of the moon. The image displayed shows the topography of moon as the third dimension of the two-dimensional map through the use of color.

PLSS

The PLSS typically divides land into 6-mile-square townships, which is the level of information included in the National Atlas. Townships are subdivided into 36 one-mile- square sections. Sections can be divided even further into quarter sections, quarter-quarter sections, or irregular government lots. Usually, a permanent monument, or marker, is placed at each section corner. Monuments are also placed at quarter-section corners and at other important points, such as the corners of government lots.

The map that I used is an example is a map of Franklin County, Alabama where some of my family is from.

Cadastral Map

A cadastral map provides detailed information about property in a specific area. An example of a cadastral is this map  below displaying a village which shows the boundaries of all of the parcels or lots within the village, although cadastral maps can show other types of areas as well. A cadastral map can include a number of details, including information about tax rates, who owns the land, which kinds of structures are present, and what the zoning is in the region

Topographic Map

A topographic map is large-scale map showing relief and man-made features of a portion of a land surface distinguished by portrayal of position, relation, size, shape, and elevation of the features. Here is a topographic map of the state of Florida.

Thematic Map

A thematic map is a type of map or chart especially designed to show a particular theme connected with a specific geographic area.This particular thematic map demonstrates the breakdown of land reserves on a Hawaiian island. It can used by Hawaiian real estate agencies presentations or publications.

Isopach Maps

Isopach maps illustrate rock or sediment thickness using contour lines. The map shown here shows the thickness of sediments beneath Long Island.
