LIDAR

LIDAR (light detection and ranging) is a laser-based imaging system that displays high-accuracy, high-density elevation data. This LIDAR image was from September 15, 2001 after the 9-11 tragedy and shows a 3-D model of the elevation of New York City in relation to the destruction/debris from the attack. Several of these images were taken over a span of several days to show the change in elevation of the destruction.

Statistical Map

A statistical map uses colors and legends to display statistical information and ranges for the information being analyzed. In this statistical map, the United States Census Bureau is trying to show where the most population change in both metropolitan and micropolitan areas in the United States has changed over a 5 year period. Using the shading from lightest to darkest to indicated the lowest to highest amount of population change and the legend to reinforce the statistical numbers, the chartographer was effective in conveying his or her message.

Cartogram

A cartogram is a map where area is not preserved and instead another thematic mapping variable is substituted for land area. The map is distorted in order to project the information of this other variable. In this cartogram, the earth's continents are distorted in order to portray each area's consumption in relation to the rest of the world. The distortion and coloring in the map is a way to more accurately display a particular area's "footprint" on the world.
