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.
