        abstract:  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.
        purpose:  The purpose of this LiDAR data is to support transportation planning within the Road to Resources Program in Alaska.

TIN data have been produced in AutoCAD Civil3D from the model key points. The Civil3D TIN has been independently certified by an Alaska PLS to meet or exceed ASPRS class 2 accuracy for 2 ft contours. OCM found that there were 2 different values found for the vertical accuracy in two reports available for this data set. According to the Tetra Tech report referenced in the URL section of this metadata record, the value is 0.60 ft/18.3 cm RMSE. According to the UAF report, also referenced in the URL section of this metadata record, the value is 0.46 ft/14 cm RMSE.

                description:  The LiDAR data for the Hoonah corridor area was acquired July 16, 18 and 21 of 2014. SBET and shapefile of the trajectory are located with the point cloud data. The data was post processed through PosPac, Waypoint’s GPS and IMU (inertial measurement unit) post processing software, and LMS, Optech’s LiDAR post processing software. PosPac is used to generate the trajectory file which contains the position (X, Y, Z) from differential GPS observations and the plane’s attitude (roll, pitch, heading) from the IMU. LMS is used to join the discreet point range information to the trajectory information through a common time stamp and to calibrate the data. The calibration is achieved by first identifying common features in the overlap of adjacent flight lines, and then adjustments are applied to the IMU’s angular offsets to align the data. Once finished, LMS refines the calibration further through a bundle adjustment to create the final calibrated data set. Classification of the calibrated LiDAR data set is achieved through the use of TerraScan, the industry standard software from TerraSolid for classifying LiDAR. Individual macros were defined that derive and refine a ground surface, vegetation, and buildings. These macros are also used to eliminate spurious points below the surface and high point artifacts. The Hoonah area was then manually checked and edited to eliminate low and high points as well as to ensure that points are classified appropriately.
            processStep:  (LI_ProcessStep)
                description:  The NOAA Office for Coastal Management (OCM) downloaded 158 laz files from the Alaska Division of Geological and Geophysical Surveys data Portal (https://elevation.alaska.gov/). The files contained classified elevation and intensity measurements for the 2014 Hoonah data set. The data were in Alaska State Plane, Zone 5001 coordinates (NAD83, US survey feet) and NAVD88 elevations (GEOID12A) in feet. The data were classified: 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. OCM processed all points to the Digital Coast Data Access Viewer (DAV). OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. The LAStools software scripts lasinfo and lasvalidate were run on the laz files to check for errors. 2. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges. 3. Internal OCM scripts were run on the laz files to convert from Alaska State Plane, Zone 5001 coordinates to geographic coordinates, to convert from NAVD88 elevations to ellipsoid elevations using the GEOID12A model, to convert from feet to meters, to assign the geokeys, to sort the data by gps time and zip the data to database and to http.

                description:   The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID12B) meters, using the GEOID12B grids provided by the National Geodetic Survey. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org) Processing notes:
