TheU.S. Interagency Elevation Inventorya comprehensive listing of known high-accuracy topographic and bathymetric data for the U.S. and its territoriesisnow availablevia NOAAs Digital Coast website (www.csc.noaa.gov/digitalcoast/tools/inventory). The inventory displays lidar, interferometric synthetic aperture radar, and bathymetric data; bathymetry includes NOAA hydrographic surveys, multibeam data, and bathymetric lidar. In addition to graphic displays of data set footprints, listings also provide information that includes vertical accuracy, point spacing, date of collection, and often a direct link to download data. This project is an annually updated collaborative effort between the NOAA Coastal Services Center and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency.
