2004 UC Proceedings Abstract
 The National Map Hazards Data Distribution System Track: Homeland Security Author(s): Brenda Jones The U.S. Geological Survey (USGS) EROS Data Center (EDC) responds to emergencies on behalf of various government agencies for human-induced and natural disasters. This response consists of satellite tasking, imagery acquisition, image registrations, disaster-extent maps, data processing and photographic laboratory services, Web-based mapping services for product delivery, and post-disaster data archiving and distribution. EDC staff also work on disaster preparedness, including providing base data such as satellite images, vector data layers, and other pre-disaster data. These data augment eight base layers provided by The National Map and are incorporated into a Web-based browser and data delivery service, The National Map Hazards Data Distribution System (HDDS). These data are made available until the usage for a particular event declines substantially; then they are moved to a near-line archive. When usage has declined completely, the data are stored in an off-line archive. A goal of HDDS is to anticipate customer requirements and provide efficient delivery of disaster data and services.
