A digital library of flood-inundation maps is being produced for St. Paul, Minnesota, in a geographic information system by combining results from a one-dimensional hydraulic model with high-resolution digital elevation data. The high-resolution digital elevation data, obtained from aerial lidar sensors, and aerial photography (National Agriculture Imagery Program (NAIP)) provided a backdrop for the flood inundation maps. The availability of these maps, along with information regarding current river stage from USGS streamgage and forecasted river stage from the National Weather Service, will provide enhanced flood warning and visualization of the potential impacts should a flood be forecast for St. Paul and its residents.
