Aug 1, 2014 -- Save time. Save resources. Find out what elevation data sets are available and where to get them by using the newly updated U.S. Interagency Elevation Inventory. This curated source of information about available elevation data can reduce duplication of effort in data collection and provides one source for finding and accessing data. Inventory users get a comprehensive, nationwide listing of high-accuracy topographic data, primarily lidar, as well as bathymetric data, including NOAA hydrographic surveys, multibeam data, and bathymetric lidar.
These data are shown on a map with their geographic extents, and each entry includes information about vertical accuracy, point spacing, and date of collection. A direct link to the data download site is included when available. The inventory was updated in June 2014.
This inventory is provided to the public through the NOAA Digital Coast and is kept up to date through a partnership between the National Oceanic and Atmospheric Administration and the U.S. Geological Survey, with contributions from the Federal Emergency Management Agency.
