Hazards Data Distribution System

After a major disaster, a satellite image or a collection of aerial photography is frequently the fastest, most effective way to determine the scope and severity of the event. The USGS operates the Hazards Data Distribution System (HDDS) to process and deliver satellite and aerial imagery in near-real time during natural or human-caused disasters such as hurricanes or oil spills.  The USGS used satellite imagery to help assess the scope of damage from the massive Grand Mesa mudslide in Colorado in May 2014.  The imagery from HDDS has also been used to support the response to over 33 fires during 2014. The data are provided in response to requests from the U.S. Forest Service, Bureau of Land Management, National Park Service, and State fire agencies. The imagery is available to all U.S. emergency management officials at the Federal, State, local, and Tribal levels.
