NOAA has an outfit which flies and takes aerial imagery after hurricanes hit to collect important data about the damage these storms cause. Google first worked with this team after Hurricane Katrina hit and the release of the imagery helped many people in response to the disaster. Now Google has once again worked with NOAA and released a Hurricane Ike Google Earth overlay showing new imagery taken after the storm. You can compare the current Google Earth imagery (from before the storm) with the newer NOAA imagery taken after the storm hit. To do this, select the “Hurricane Ike 2008” folder and drag the slider below the Places pane which changes transparency. You can visit NOAA’s Hurricane Ike Response page for more information. Here’s a sample comparing before and after:
There is also similar imagery available for Hurricane Gustav from a few weeks ago.
