Black and White Aerial Photo


Black and white aerial photographs can be very beneficial in showing landforms, vegetation, and resources. They make landscape features more easily understood on a regional, continental, and even global scale. This photograph shows a neighborhood and major highway.

Infrared Aerial Photo


Geographers use a camera to capture a certain band of light called infrared. These images can be used specifically to document changes in the environment and the health of forests, wetlands, bays and oceans. This image shows water near land plots.

Cartographic Animations


A cartographic animation is a map that has moving aspects which show us what could happen under certain circumstances. In this case, the animation shows the development and movement of Hurricane Katrina.

Statistical Map



Statistical maps are based upon numerical values and gives a standard statistic with regards to a specific period of time. The given map depicts statistical changes in burglaries in the Denver, Colorado area.

Cartogram


Cartogram maps scale the area of each country in proportion to its population. The shape and relative location of each country is retained to as large an extent as possible, but a large amount of distortion tends to always exist. This map shows the amount electoral votes each state got by the number of squares that make up the state.

Choropleth Map



A Choropleth map is a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map. This map shown shows the divorce rate increase in each state based on color.

Dot Distribution Map


Dot distribution maps are used to show the presence of a feature or occurrence and display a spatial pattern. The map shown here shows the size of populations of cities in the United States based on dot distribution.

Propaganda Map

A Propaganda map is created to express a biased opinion and convince others of it, usually exaggerating specific features. This map in particular is a political satire showing President Reagan's view of the world.
