This is a LIDAR image of flooding in New Orleans after Hurricane Katrina. This image is an active sensor emission source taken from a over head plane. You can see that most of the areas directly near the bay were hit hard and experienced many feet of water. The green areas represent the areas that were under the most water followed by the yellow, orange, and red. This type of map could be used by response or rescue teams to assist in extracting victims in the major disaster areas.
