The latest Esri story map is a handy resource that reveals the latest pre and post Sandy imagery from NOAA. Using a slider action the user simply drags the red line to delineate where the pre and post imagery will be determined… amazing to see the destruction from this terrible tragedy.
The map shows NOAA imagery before and after Hurricane Sandy and lets you swipe over the map to view storm damage. You can also use the included bookmarks to explore some of the most damaged areas in the Mid-Atlantic and Northeast.
