U.S. Geological Survey Flood Inundation Mapping Science

Science Center Objects

Static flood-inundation map libraries consist of maps that have been created in advance of a flood that are ready to be served through the Internet. Each library consists of a set of flood extent and depth maps developed for predetermined stream stage intervals (for example, a map for each one foot of stage). A user can view real-time or forecast stage data from a USGS streamgage or National Weather Service flood forecast point and quickly access the map corresponding to the stage data.
