NOAA AERIAL MAPPING ASSISTING U.S. COAST GUARD, FEMA SHOWS FLOOD WATERS RECEDING IN REGIONS AFFECTED BY HURRICANE KATRINA
Sept. 12, 2005 — The NOAA Office of Response and Restoration is working closely with FEMA and the U.S. Coast Guard in coordinating the response to hazardous materials in the flood waters of New Orleans and with the continuing search and rescue mission in response to the aftermath of Hurricane Katrina.

One of the innovative technologies being applied is combining LIDAR (airborne laser used to measure topography) and aerial satellite imagery to create aerial maps of the region. NOAA is assisting in tracking the progress in removing water from the flooded areas of the region by providing aerial maps showing the progress to date.
The maps are generated using satellite imagery acquired from the Department of Defense National Geospatial Intelligence Agency combined with LIDAR (Light Detection and Ranging) data from Louisiana State University and the State of Louisiana. Research Planning Inc., a NOAA contractor, is conducting this synthesis that shows likely water depths based on the combination of data.

These maps show the progress in removing floodwaters from New Orleans following Hurricane Katrina by comparing water levels on August 31 and September 8. Note that the water depth estimates have not been verified with measurements on the ground.
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.
