Eighty percent of the American city of New Orleans, in the state of Louisiana, is now flooded by the effects of Hurricane Katrina, with some parts of the city under 20 feet of water. Two levees
were breached, including the 17th Street Canal levee. In an earlier
report, three people have died of dehydration during the evacuation
phase and another four have died at the Superdome [1].
There has been no other update of casualties since, with efforts
focusing on continued rescue rather than body-counting. Many refugees
are trapped in flooded houses and rooftops waiting to be rescued. On August 30, Louisiana governor Kathleen Blanco ordered the complete evacuation of the city of New Orleans, including the thousands of people seeking shelter in the Superdome [2].
An effort to sandbag the 17th Street Canal levee breach has failed, and
the pump which was partially offsetting the flooding has stopped
working. Major flooding is now expected, and those left in the city are
urged to leave immediately or take refuge in a second story.

 9/3 Update:

NOAA
CONDUCTS AERIAL SURVEY OF REGIONS RAVAGED BY HURRICANE KATRINA

Aug.
31, 2005 — NOAA today 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. (Click

Update,
Sept. 1, 2005: NOAA made available an additional 1,450 aerial images
of the regions impacted by Hurricane Katrina, including New Orleans.
See New Orleans images below.

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. (Click

Miss., taken on Aug. 30, 2005, after Hurricane Katrina slammed the region.

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.
