Choropleth Maps

http://www.eps.mq.edu.au/courses/GEOS219/images/deaths.jpg

A choropleth map is a type of thematic map. Areas are shaded or patterned in proportion to the variable being displayed. There are many different types of choropleth maps, all having different ways of portraying the variable. This choropleth map shows the deaths per 1000 live births in Australia. The deaths are represented by the shading, the darker the shading, the higher the death rate is and vice versa.

A Hypsometric map is a topographic map that portrays the different ranges of elevation with different shades of a color. The relief of an area is shaded in relevance to it's height. For example, in this topographic map of Maryland, you can see that the higher parts of elevation are located in the west of the state, because the darker the shade, the higher the elevation.

Unclassed Choropleth Maps

An Unclassed Choropleth map portrays it's data values by shading. An unclassed choropleth map does not break down the information into intervals. Instead of knowing the exact numeric data, you have to analyze the map on its shading. The darker the shading, the higher the numeric value is, and the lower the numeric value is, the softer the shading will be.

A Classed Choropleth map is a type of choropleth map that portrays information that is classified and broken down into different intervals. This map's information is classified and broken down into 4 intervals of ages.

Parallel Coordinate Graph

A parallel coordinate graph is a graph that plots all the points of data set on one single graph. By doing this, it is easy to understand and compare the distribution of data. From this parallel coordinate graph it is easy to see information about the data set for example, the highest and lowest value points .

Continuously Variable Proportional Circle Map

A Continuously variable proportional circle map utilizes circles to portray the size of the value point. A circle will be proportional to the size of the data for a specific variable. Sometimes, information can be given within the circle, like this map above.

Black and white photos give a unique look to areas and images. Black and white infrared film is sensitive to a specific light spectrum and have a high sensitivity to blue light wavelengths. Black and white photos are usually shot at weddings, for landscape, and for art. This image is a black and white picture of Destin, Fl.
