Parting Shots

Affecting more than 20 states, the scope of Hurricane Sandy, and the rebuilding efforts underway and yet to come, are difficult to imagine. Using geographic information system (GIS) mapping, technology companies Esri and Microsoft are providing a big-picture view of the hurricane impacts using National Oceanic and Atmospheric Administration (NOAA) satellite imagery. A map available at local.msn.com/weathersandyaftermap compares before and after images of Hurricane Sandy.

The graphics below show an area near Breezy Point Reid Beach in New York. Even from quite a distance, the images show portions of homes and entire structures moved from their foundations.

For links to more images, many of which show great system performance, visit this slideshow on the Wall Street Journal's website, or this collection of images from Google images.
