This map of the United States and its territories shows the areal extent and quality level of planned, in-progress, and existing publicly available lidar (IfSAR in Alaska) data identified by the United States Interagency Elevation Inventory (USIEI) that meet 3DEP base level specification planned to be under award by September 30, 2024. 3DEP base level specification data are defined as quality level 2 or better lidar data (IfSAR in Alaska) and 8 years or old or newer. The inventory was produced in partnership by the U.S. Geological Survey (USGS) and National Oceanic and Atmospheric Administration (NOAA). While every attempt has been made to accurately inventory projects that are publicly available, some errors and omissions may occur.
