Sandy is a major storm that has caused extensive flooding, physical damage, power and transportation outages, and multiple fatalities in NY and much of the US East coast.

NOAA’s National Geodetic Survey's remote sensing program conducts aerial photographic surveys the coast to document coastal damage and impacts to navigation. 

The data contained in these photos provide emergency and coastal managers with the information they need to develop recovery strategies, facilitate search-and-rescue efforts, identify hazards to navigation and HAZMAT spills, locate errant vessels, and provide documentation necessary for damage assessment through the comparison of before-and-after imagery.
