NOAA Conducts Aerial Survey Of Regions Ravaged By Hurricane Katrina

ScienceDaily (Sep. 2, 2005) — NOAA has posted online more than 350 aerial images of the U.S. Gulf Coast areas that were decimated by Hurricane Katrina. NOAA will be flying more missions in the days ahead that will yield hundreds of additional aerial digital images. The regions photographed on Tuesday range from Bay St. Louis to Pascagoula, Miss. The southeast coastal areas of Louisiana are being photographed on Wednesday. The aerial photograph missions were conducted by the NOAA Remote Sensing Division the day after Katrina made landfall at approximately 7:10 a.m. EDT on Aug. 29, 2005, in Plaquemines Parish, La.

NOAA used an Emerge/Applanix Digital Sensor System, or DSS, to acquire the images from an altitude of 7,500 feet. The equipment was mounted on NOAA’s Cessna Citation aircraft, which is a versatile twin-engine jet aircraft modified for acquiring coastal remote sensing imagery. The aircraft can support a wide variety of remote sensing configurations, including large format aerial photography, as well as data collection for digital cameras, hyperspectral, multispectral and LIDAR systems.

The NOAA Cessna Citation aircraft acquired 3-D images of the World Trade Center and Pentagon just days after the attacks on Sept. 11, 2001.

The NOAA imagery was acquired to support the agency’s national security and emergency response requirements. In addition, the imagery will be used for ongoing research efforts for testing and developing standards for airborne digital imagery.

NOAA, an agency of the U.S. Department of Commerce, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of the nation's coastal and marine resources.
