The Google Earth team has worked hard this weekend and has updated their earlier release of imagery. The first part includes even more NOAA imagery of the damaged areas. Click here to download the new network link enabled overview of the entire collection. This network link will automatically update to the latest imagery. You will see dots where the images are located and can individually load each image. As before, these are large images and you may not want to turn too many on at the same time due to computer memory.
Google has also developed a very cool dynamic overlay of imagery from Digital Globe of the New Orleans area. This is a network link which is based on your current view which will load tiles of images. Download this link here .
