Tetra Tech was contracted by the University of Alaska Fairbanks (UAF) to provide LiDAR and ortho-imagery data for the Road to Resources in Alaska Program. Tetra Tech collected LIDAR data and aerial imagery during the fall of 2013 and the spring/summer of 2014.
This classified point cloud data is part of a data set of LiDAR point cloud data, derived elevation products and orthoimagery. The data were acquired along 5 corridors in South Eastern Alaska near Ketchikan and Juneau. The data were procured by GINA (Geographic Information Network of Alaska) at the University of Fairbanks (UAF) on behalf of the Alaska DoT (Department of Transportation). The 5 corridors are identified as Anita Bay, Bradfield to Behms, Hoonah, Revilla and Wrangell. The classified data has been classified as follows: Class 1: Unclassified, Class 2: Bare-earth ground, Class 3: Low vegetation, Class 4: Medium Vegetation, Class 5: High Vegetation, Class 7: Noise, Class 8: Ground Model Keypoints, Class 9: Water, Class 14: Bridge Decks.
The NOAA Office for Coastal Management (OCM) downloaded this lidar data from the AK DGGS site (https://elevation.alaska.gov/) and processed the data to be available on the Digital Coast Data Access Viewer (DAV). OCM processed all points to the Digital Coast Data Access Viewer (DAV).
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
