Attachment D: FY17 Status of 3DEP Quality Data

Attachment D: 3D Elevation Program FY17 Status of 3DEP Quality Data

Map showing the areal extent and quality level of planned, in progress, and existing publicly available lidar (IfSAR in Alaska) data identified by the U.S. Interagency Elevation Inventory (USIEI) that meet 3DEP base-level specification as of June 2016. 3DEP base-level specification data are defined as quality level 2 or better lidar data (ifsar in Alaska) and 8 years old or newer. The inventory was produced in partnership by the U.S. Geological Survey and the National Oceanic and Atmospheric Administration. While every attempt has been made to accurately inventory projects that are publicly available, some errors and omissions may occur.

Legend:

Dark Green = Meets 3DEP base-level specifications for lidar

Dark Blue = Meets 3DEP base-level specifications for IfSAR (Alaska)

Grey = Other lidar

Beige = No publicly available lidar data or IfSAR (Alaska only)
