DOQQ
DOQQ
DOQQ maps are made using characteristics of an aerial image. This areal image uses geometric features of a map. Distortion is omitted so these images are abled to be used as flat maps. This image take from a photograph in South Carolina and turned into a computer image, you can observe the obvious displacement of the terrain.
Infrared Aerial Photo
Infrared Aerial Photo
An infrared aerial map is done using photography and can a powerful tool. Not only beneficial for the environment but can be used to monitor damage to infrastructure, used my law enforcement or even track toxic chemical. The example here is that of a football stadium, you can see how dark the field looks because it is made of turf compared to its surrounding environment.

Cartographic animations
When it comes to cartography animation is very importation in the representation of the information and data. By definition as a graphic art that occurs in time animation is a visual statement that evolves through change in the display. We see this daily on the weather channel which is where my example is from. As time and technology evolves this has become much easier to present.
Statistical Maps
Statistical Maps
This map shown is a Statistical map and can be used to depict representations of distances apart from physical distance. Shown is that from the national data book in 2006 showing the average travel time to work. Again colors are used and those states that are darker have higher times to get to work.

Proportional Circle Maps
Proportional Circle Maps
Proportional Circle maps use different sized circles to show differences between two place as we see in the above example depicting the Czech Republic. These maps areas are shaded with colors that are referenced in the key to the lower left. This images shows the population density information using a choropleth map.
