Isotachs

Isotachs are defined as a line in a given surface connecting points with equal wind speed. The isotach shown above is an example of upper level dynamics and Mesolow development.

Isobars

"A line drawn on a weather map connecting points of equal pressure is called an isobar. The isobars are generated from mean sea level pressure reports and the pressure values are given in millibars (http://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/prs/isb.rxml)." This picture shown above is actually an example of parallel isobars.

LIDAR

A lidar uses laser (light amplification by stimulated emission of radiation) instead of radio or microwave radiation. Like my last example, this lidar map displays one of the most horrific things to happen in the US. This LIDAR map shows the aftermath of the World Trade Center Terrorist attack. This photo was taken at an altitude of 3,300 feet above ground zero.

Doppler Radar

Doppler radar is a system for measuring speed that is based on the doppler effect. The doppler effect according to google definition is "The observed change in the frequency of sound or electromagnetic waves due to the relative motion of the source and observer." This Doppler radar photo was taken of Hurricane Katrina in the midst of the massive crisis that took place a few years ago =(

Black and White Aerial Photo

The photo pictured above is an example of a black and white aerial photo. Black and white aerial photos are used to distinguish more detail in a picture. This black and white aerial photo is a photo taken of a former train yard also known as the balloon track site.

Infrared Aerial Photo

Infrared aerial photography is a powerful tool that can be used to document changes in the environment, health of wetlands and forests, and even monitor sites contaminated by toxic chemicals (http://www.aerialarchives.com/Infrared-Aerial-Photography.htm). The above example of infrared aerial photography is a photograph of the Onondaga Lake area.

Cartographic Animations

This example of cartographic animation depicts data found after Mt. Saint Helens erupted in 1979. Cartographic animation is used fairly regularly and is a great tool because it helps people better visualize and take in the data they are being shown.
