Use of VIIRS Day-Night Band Imagery in Response to Hurricane Sandy Recovery Efforts
In late October 2012, widespread strong winds, torrential rain, coastal flooding, and other effects of Hurricane Sandy contributed to widespread power outages throughout the northeastern United States. In response to this disaster, SPoRT provided SNPP VIIRS day-night band imagery and an experimental, false color blackout composite. SPoRT's experimental "blackout composite" of pre-storm and post-event imagery helped to identify missing lights in a single image. Through collaboration with NASA's Applied Sciences Disasters Program, daily composites were provided to the United States Geological Survey's Hazards Data Distribution System, where they were then distributed to the Department of Defense (DoD) Joint Task Force-Civil Support (JTFCS).
