KML File - Week 7 assignment

http://coastal.er.usgs.gov/remote-sensing/advancedmethods/DRTO/drto_bathy_index.kmz
This KLM file on Google Earth is of the Dry Tortugas National Park (DRTO) in the Florida Keys. When you run the file you will see that this place is anything but dry. There are approximately 79 interactive location pins in this file. The pins represent submerged Topography data with a DEM image. The data pins are organized to make up a grid of 2 km x 2 km tiles. There is also an elevation color bar at each location which demonstrates both surface topography, and submerged topography.

Proportional Circle Map

http://www.cscs.umich.edu/~crshalizi/slothblog/2006/
Above is an extreme example of a proportional circle map; this is also an example of a cartogram. This map is demonstrating the Red-Blue political divide in the US. It is broken down county by county and it is area proportional. The color demonstrates how the counties voted for either party (red/Republican, blue/Democrat) during the 2000 Presidential election. The intensity of the color signifies the degree to which the counties voted Democrat or Republican.
