Devastation from Katrina Captured by NASA's EAARL System
The following photos were taken from NASA's Experimental Advanced Airborne Research Light Detection and Ranging (EAARL) system that has been surveying the coastline of the Gulf of Mexico this week. The aircraft is taking high-resolution observations that can be used to assess the amount of damage to communities and the environment. This activity is being conducted at the request of the U.S. Geological Survey in cooperation with the Federal Emergency Management Agency and the Army Corps of Engineers.
While making its observations of the land, the system, carried on a Cessna 310, has the ability to "see" through vegetation, like trees and shrubs, to view the land underneath. Near the coast it can map the beach surface under water. This will help in the recovery of the shoreline infrastructure; determine hazard areas and environmental loss.
