LAB 2: Five Maps

Here is an example of a choropleth/ isarithmic map because it uses color and region distinction to show information. This map shows the average precipitation in the state of Georgia.  

Here is an example of an isarithmic map. Isarthmic maps use distinctive colors or shading to corresponding units according to a key on the map.

 Dot-density maps, like the one above, use a predetermined shape, color, and scale. This map uses concentration to show data trends the distances of McDonald's' locations. The more data there is in an area, more corresponding dots there will be in that area.

This map is called a proportional symbol map. It uses a fixed shape of a fixed color, but the size changes in proportion to the amount of data. Thus, the more data there is in an area, the larger the shape in that area will be. Here, the larger the red circles are in a state the more murders occur in that state. 

This is a choropleth map. It uses different colors to help quickly visualize general data trends over larger areas. This map looks at the estimated household income in the of year 2008. The different colors used represented an average income base on the scale in the bottom right hand corner.
