The damage of Katrina seen by Google Earth

A natural disaster brings out the need for up-to-the-minute maps and images, and Google Earth community members have created more than 100 overlays in the last 24 hours that tell the story of Hurricane Katrina's effect. These overlays drape on top of existing satellite images, and NOAA has been posting these flyovers so people can actually see the incredible devastation
