HDDS Help Documentation
The Hazards Data Distribution System (HDDS) Explorer is a unique collection of imagery and documents designed to assist in the response to natural and man-made disasters. Like a traditional web-based interface to an imagery archive (such as EarthExplorer), HDDS provides geographic search capabilities based on latitude and longitude boundaries and other criteria. HDDS contains imagery acquired in the aftermath of a disaster as well as imagery of the same region before the event.
