[PDF] [JPG] [TIFF]

This poster shows Landsat satellite images of New Orleans, Louisiana, as floodwaters from Hurricane Katrina begin to recede. The image on the far left was acquired by Landsat 7 on August 30, 2005, one day after Katrina made landfall. The middle image was acquired by Landsat 5 on September 7, 2005, one week after the hurricane hit, and the image on the far right was acquired by Landsat 7 on September 15, 2005, two weeks after the hurricane devastated the region.

This recent MODIS product shows the extent of persistent flooding resulting from Hurricane Katrina.

Of particular note is the innundation of the barrier islands of the Breton National Wildlife Refuge and the coastal marshes which lie to the southeast of the city of New Orleans. Recent reports indicate that these features may be permanently lost.

Topography-Based Analysis of Hurricane Katrina Inundation of New Orleans [PDF] [JPG] [TIFF]

High-resolution, high-accuracy elevation data derived from lidar data collected in 2002 have been used extensively during the first weeks of recovery from Hurricane Katrina. The precise topographic measurements provided by lidar have proven very useful for various mapping activities in the low relief environment of New Orleans.

This poster was produced at USGS/EROS using 2002 lidar data. Because an accurate delineation of the inundated area from remote sensing data was not yet available, the flood water level within the city was derived from a lake level gage on Lake Pontchartrain, with the assumption that the level of the lake and the floodwaters had equalized by the afternoon of Friday, September 2, 2005. Comparison with subsequent imagery has shown the flood delineation to be a reasonable depiction.
