NASA Post-Hurricane Katrina Images Available On Google Earth


When Hurricane Katrina made landfall in August 2005, it changed the look of some of the coastlines of three U.S. states. Now, using Google Earth’s software on the Internet, people can see the before and after affects, thanks to detailed images from NASA and the U.S. Geological Survey (USGS).

The images on Google Earth show changes that Hurricane Katrina made to the Gulf coast from Panama City, Fla. to New Orleans, La.

Hurricane Katrina made landfall in south Plaquemines Parish, La., near the towns of Empire, Buras and Boothville, on Aug. 29, 2005, at approximately 7:10 a.m. CDT. It caused widespread destruction in Louisiana, Mississippi, and Alabama and turned out to be the most expensive hurricane in the history of the United States, causing an estimated 80 billion dollars in damages, according to the National Oceanic and Atmospheric Administration. Katrina also turned out to be the deadliest U.S. hurricane since 1928, claiming at least 1,300 lives.

The coastlines of those states were forever changed. NASA, using an Atlantic Global Research contract aircraft and the agency’s own advanced technology, made it possible to see how much and what type of damage that Katrina caused when it came ashore.

The changes to the coasts were cataloged in detail using NASA’s laser mapping system called EAARL (Experimental Advanced Airborne Research Lidar) onboard an airplane. EAARL uses a laser to "see" and measure distance to a surface. EAARL can be used to get closer looks at things like coral reefs, sandy beaches, coastal vegetation, and trees.

During the month of September, 2005, 250,000 pictures were taken over 5 days of flying over the coastlines.

The EAARL Principal Investigator, Charles W. Wright, of NASA’s Wallops Island Flight Facility, Wallops, Va., placed the imagery online at Google Earth. "This is the first time that I can remember such an easy-to-use tool putting so much data at the fingertips of so many people with so little effort,” Wright said.

Wright said that the people involved with the project were busy working to bring the lidar data of the New Orleans levees online for FEMA, and had not anticipated that they would be bringing the photography online.

The U.S. Geological Survey’s Coastal and Marine Geology Program investigates the how much coastlines change due to hurricanes and other powerful storms. A big benefit to using this is that it will help people make decisions on where to rebuild.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Alliance „OLED Licht Forum“ – Key partner for OLED lighting solutions

Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, provider of research and development services for OLED lighting solutions, announces the founding of the “OLED Licht Forum” and presents latest OLED design and lighting solutions during light+building, from March 18th – 23rd, 2018 in Frankfurt a.M./Germany, at booth no. F91 in Hall 4.0.

They are united in their passion for OLED (organic light emitting diodes) lighting with all of its unique facets and application possibilities. Thus experts in...

Im Focus: Mars' oceans formed early, possibly aided by massive volcanic eruptions

Oceans formed before Tharsis and evolved together, shaping climate history of Mars

A new scenario seeking to explain how Mars' putative oceans came and went over the last 4 billion years implies that the oceans formed several hundred million...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
