Yesterday I posted a Google Earth file marking all the churches in our Gulf Coast Baptist Association. The screen shot showed the pre-storm satellite imagery of our church currently displayed in Google Earth by default. The National Oceanic & Atmospheric Administration (NOAA) snapped satellite images a few days after the storm. You can dynamically overlay these images, within Google Earth, by downloading the katrina-overlays-netlink.kml file. Navigate to the gulf coast and click on one of the blue, red, or yellow dots to pull up the ability to view the overlays for that location. Choose the 4kX4k version for the sharpest detail.
