The National
Map Hazards Data Distribution System (HDDS)/Asian Tsunami
The U.S. Geological
Survey is playing a vital role through its National
Center for Earth Resources Observation and Science (EROS) in relief
efforts to nations impacted by the Asian tsunami disaster of December
26, 2004. EROS maintains the world's largest collection of civilian
remotely sensed data of the Earth's land surface. Within hours after
the disaster occurred, EROS began providing relief organizations worldwide
with pre- and post-tsunami satellite images, as well as image-derived
products that incorporate information on population density, elevation,
and other relevant topics. These images and image-derived products are
being used by relief organizations to make practical, well-informed
decisions as to where relief efforts are most urgently needed and how
best to carry out those efforts.
