For more than two decades, the emergency management community has articulated a need for real-time, street-level flood inundation maps depicting the areal extent, depth, and infrastructure impacted by flood waters, to inform critical decisions that save lives and property before, during, and, after a flood event. NOAA will collect and integrate high-resolution bathymetric and topographic data to advance flood and inundation mapping capabilities, particularly for previously underserved communities inland and along the coast. NOAA tracks the progress of making real-time flood inundation mapping services available for 100% of the U.S. population, using Oak Ridge National Laboratory LandScan 2019 data and the latest Census data to assess how many residents lie within the areas served by FIM.
