Here is a satellite overlay of New Orleans that was taken on August 30, 2005. There are a number of clouds in the picture, but you can see the dark green flooded areas to get an idea of the damage.
This overlay shows the elevation levels of New Orleans, LA , along with Metairie, Kenner, Harahan, Arabi, Gretna, and Westwego, allowing easy determination of the flood zones.
