Data Management Plan
DMP Template v2.0.1 (2015-01-01)Please provide the following information, and submit to the NOAA DM Plan Repository.
Reference to Master DM Plan (if applicable)
As stated in Section IV, Requirement 1.3, DM Plans may be hierarchical. If this DM Plan inherits provisions from a higher-level DM Plan already submitted to the Repository, then this more-specific Plan only needs to provide information that differs from what was provided in the Master DM Plan.
1. General Description of Data to be Managed
Because no metadata record was provided with the Anita Bay data, this record was created by the NOAA Office for Coastal Management (OCM) based on information supplied in the Anita Bay Corridor Quality Assurance Report, the Tetra Tech UAF Light Detection and Ranging (LiDAR) and Ortho-Imagery Data Project Revilla Corridor, and the Hoonah metadata. Links to both reports are provided in the URL section of this record.
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.
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).
In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

Programs must identify resources within their own budget for managing the data they produce.
5. Data Lineage and Quality
NOAA has issued Information Quality Guidelines for ensuring and maximizing the quality, objectivity, utility, and integrity of information which it disseminates.
(describe or provide URL of description):
- The LiDAR data for the Anita Bay corridor was acquired June 27 of 2014. SBET and shapefile of the trajectory are located with the point cloud data (see Figure 2 for the organization of LiDAR and LiDAR derived 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 Anita Bay area was then manually checked and edited to eliminate low and high points as well as to ensure that points are classified appropriately. Breaklines were derived from LiDAR and imagery and help define water classes in the LiDAR data.
- 2018-08-30 00:00:00 - The NOAA Office for Coastal Management (OCM) downloaded 16 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 Anita Bay 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. 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. LAStools las2las script was run to convert the gps times from week to adjusted. 4. 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 assign a lidar domain profile, to sort the data by gps time and zip the data to database and to http.

7. Data Access
NAO 212-15 states that access to environmental data may only be restricted when distribution is explicitly limited by law, regulation, policy (such as those applicable to personally identifiable information or protected critical infrastructure information or proprietary trade information) or by security requirements. The EDMC Data Access Procedural Directive contains specific guidance, recommends the use of open-standard, interoperable, non-proprietary web services, provides information about resources and tools to enable data access, and includes a Waiver to be submitted to justify any approach other than full, unrestricted public access.
