Floods

Mapping floodwater extent for active floods is critical for local and regional officials and for disaster relief organizations that need to ascertain where to focus their efforts. Land, Atmosphere Near real-time Capability for EOS (LANCE) provides data to the Dartmouth Flood Observatory and the near real-time (NRT) Global MODIS Flood Mapping initiative.

Potentially useful data sets: Moderate Resolution Imaging Spectroradiometer (MODIS) Corrected Reflectance True Color and Bands 7-2-1, MODIS Land Surface Reflectance Bands 1-2-1, Atmospheric Infrared Sounder (AIRS) precipitation (day and night). In Worldview, LANCE imagery can be overlaid with the following data sets from the Socioeconomic Data and Applications Center (SEDAC): Flood Hazard Frequency and Distribution, Flood Hazard-Mortality Risk and Flood Hazard Economic Risk.
