AB: The U.S. Geological Survey 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 and acquisitions, satellite image registrations, disaster-extent maps analysis and creation, base image provision and support, Web-based mapping services for product delivery, and post disaster data archiving. The EDC Emergency Response staff are on call at all times and have access to many commercial and government satellite and aerial photography tasking authorities. They have access to data processing and photographic laboratory services for off-hour priority requests. EDC staff work with agencies for preparedness planning, which includes provision of base imagery. These data may include digital elevation models, hydrographic models, base satellite images, vector data layers such as roads, aerial photographs, and other pre-disaster data. These layers are incorporated into a Web-based browser and data delivery service, the Hazards Data Distribution System (HDDS). The HDDS can be made accessible either to the general public or to specific agencies. As usage of data for a particular event declines, the data are moved to a post disaster near-line archive that is still accessible, but not in real time. When usage has declined completely, the data are moved to an off-line archive. These data are still accessible, although not in real time, and can be reloaded for historical purposes if another disaster strikes the same area. The HDDS concept anticipates customer requirements and provides faster delivery of data and services. Pending final USGS approval.
