Aerial rapid assessment of hurricane damages to northern Gulf coastal habitats
Hurricane Katrina made landfall in southeast Louisiana on August 29, 2005, and Hurricane Rita made landfall in southwest Louisiana on September 24, 2005. Scientists from the U.S. Geological Survey (USGS) flew aerial surveys to assess damages to natural resources and to lands owned and managed by the U.S. Department of the Interior and other agencies. Flights were made on eight dates from August 27

ASTER and USGS EROS emergency imaging for hurricane disasters
Satellite images have been extremely useful in a variety of emergency response activities, including hurricane disasters. This article discusses the collaborative efforts of the U.S. Geological Survey (USGS), the Joint United States-Japan Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Science Team, and the National Aeronautics and Space Administration (NASA) in responding t

GIS for the Gulf: A reference database for hurricane-affected areas
A week after Hurricane Katrina made landfall in Louisiana, a collaboration among multiple organizations began building a database called the Geographic Information System for the Gulf, shortened to "GIS for the Gulf," to support the geospatial data needs of people in the hurricane-affected area. Data were gathered from diverse sources and entered into a consistent and standardized data model in a

USGS Rocky Mountain Geographic Science Center’s 2005 hurricane response and recovery activities
Sophisticated monitoring systems and analysis products were key components to emergency response and Federal recovery activities during the 2005 hurricane season. The U.S. Geological Survey's (USGS) Rocky Mountain Geographic Science Center worked with a number of Federal agencies to provide these types of near real-time geospatial monitoring systems and analysis products in support of crucial prea

Data access and dissemination for emergency response and long-term recovery efforts related to Hurricanes Katrina and Rita
The U.S. Geological Survey's (USGS) National Wetlands Research Center (NWRC) responded to Hurricanes Katrina and Rita by providing geospatial support to Federal, State, and local partners. The NWRC used its data and information management systems to deliver aerial photography and maps to emergency responders in a time of critical need.

Temporal analysis of floodwater volumes in New Orleans after Hurricane Katrina
Satellite images from multiple sensors and dates were analyzed to measure the extent of flooding caused by Hurricane Katrina in the New Orleans, La., area. The flood polygons were combined with a high-resolution digital elevation model to estimate water depths and volumes in designated areas. The multiple satellite acquisitions enabled monitoring of the floodwater volume and extent through time.

Topography-based analysis of Hurricane Katrina inundation of New Orleans
The ready availability of high-resolution, high-accuracy elevation data proved valuable for development of topographybased products to determine rough estimates of the inundation of New Orleans, La., from Hurricane Katrina. Because of its high level of spatial detail and vertical accuracy of elevation measurements, light detection and ranging (lidar) remote sensing is an excellent mapping technolo

Hurricane Katrina flooding and oil slicks mapped with satellite imagery
A multiple-database approach that combined remotely sensed data from Radarsat-1 and Landsat Thematic Mapper Plus (ETM+) imagery was used to map Hurricane Katrinainduced flooding and to identify offshore oil slicks. Maps depicting the areal extent of flooding, oil slicks, and floating debris provide vital information to emergency managers for directing floodrelief efforts and the clean-up of pollut

Estimation of post-Katrina debris volume
Hurricane Katrina severely impacted coastal Mississippi, creating large quantities of building and vegetation debris. This paper summarizes techniques to estimate vegetation and nonvegetation debris quantities from light detection and ranging (lidar) data and presents debris volume results for Harrison County, Miss.

Analysis of the Interstate 10 Twin Bridge’s collapse during Hurricane Katrina: Chapter 3D in Science and the storms-the USGS response to the hurricanes of 2005
The Interstate 10 Twin Span Bridge over Lake Pontchartrain north of New Orleans, La., was rendered completely unusable by Hurricane Katrina. The cause of the collapse of the bridges generated great interest among hydrologists and structural engineers as well as among the general public. What made this case study even more important was the fact that two nearby bridges sustained the effects of the

Geotechnical reconnaissance of the Mississippi River Delta flood-protection system after Hurricane Katrina
This article presents the post-Hurricane Katrina conditions of the flood-protection system of levees and floodwalls that failed in the environs of the Mississippi River Delta and New Orleans, La. Damage conditions and suggested mechanisms of failure are presented from the geotechnical point of view.

Using geospatial technology to process 911 calls after Hurricanes Katrina and Rita
The flooding that ensued in the Greater New Orleans area after Hurricane Katrina left thousands of victims trapped and in need of emergency rescue. This paper describes the processing of raw 911-call data into search and rescue products used by emergency responders after the storm.
