Imagery from NOAA
After Hurricane Gustav passed on Tuesday, NOAA's Remote Sensing Division began flying rapid response aerial reconnaissance missions of the Mississippi delta region where the storm came ashore. The data they gathered are primarily to help emergency managers visualize conditions on the ground, but are also useful for anyone interested in the impact a major hurricane has on the landscape. The NOAA team has published the data they have collected so far on their official Hurricane Gustav response page, and members of the Google Earth team have processed it into a KML image overlay for easy access by anyone.
