The Dartmouth Flood Observatory performs research and collects data on the space-based measurement of surface water "for research, educational, and humanitarian applications." On their homepage visitors are presented with a global map of current flooding, complemented by links to data sets related to historic flood levels from 1985 to the present. Visitors can also click on the "Active Archive of Large Floods" section for additional materials, such as an animation that depicts these mega-events. Moving on, the site also includes a link to the "Space-based Atlas of the Earth's Changing Surface Water". Here visitors can look over sample regional maps, and also look at detailed maps of the Mekong Basin from 2000 to 2006. The site is rounded out with some information about current staff members and a list of their publications.
