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
Product: 1-meter bare-earth raster digital elevation model (DEM) data tiles in GeoTIFF format.
Geographic Extent: Approximately 47 square miles encompassing the Pilgrim Hot Springs area of Western Alaska.
The State of Alaska Division of Geological & Geophysical Surveys (DGGS) produced airborne lidar-derived elevation data for the Pilgrim Hot Springs area, western Alaska. Both aerial lidar and ground control data were collected by DGGS. This data collection is being released as a Raw Data File with an open end-user license. These data were produced in support of active fault detection and geothermal hydrology research in the area. This data collection is being released as a Raw Data File with an open end-user license. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30659).
Notes: Only a maximum of 4000 characters will be included.
Notes: Data collection is considered ongoing if a time frame of type "Continuous" exists.
Notes: All time frames from all extent groups are included.
Notes: All geographic areas from all extent groups are included.
(e.g., digital numeric data, imagery, photographs, video, audio, database, tabular data, etc.)
(e.g., satellite, airplane, unmanned aerial system, radar, weather station, moored buoy, research vessel, autonomous underwater vehicle, animal tagging, manual surveys, enforcement activities, numerical model, etc.)

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.

Process Steps:
- 2019-08-15 00:00:00 - Airborne survey - The airborne survey occurred on August 15, 2019. The weather was clear throughout the survey. This dataset includes point cloud data, a digital terrain model (DTM), and a digital surface model (DSM) covering Pilgrim Hot Springs, western Alaska (approximately 47 mi2). This survey was conducted with a DGGS-operated Riegl VUX1-LR lidar system with an integrated Global Navigation Satellite System (GNSS) receiver and Northrop Grumman inertial measurement unit (IMU) system. The integration was designed by Phoenix LiDAR systems. This survey was flown with a pulse rate between 200,000 and 400,000 pulses/second, at a scan rate between 80 and 150 scans/second. This survey was flown with an average elevation of 400 m above ground level and a ground speed of approximately 40 m/s with a fixed-wing aircraft configuration, using a Cessna 185 aircraft. The scan angle was set from 55 to 305 degrees, centered normal to the bottom of the aircraft.
- 2019-08-15 00:00:00 - Ground survey - Trimble R8 and R9 real-time kinematic GNSS systems were used to collect 62 combined checkpoints and control points for the project. Points were adjusted for accuracy according to Online Positioning User Service (OPUS) corrections in Trimble Business Center.
- 2020-01-01 00:00:00 - Lidar dataset processing - Point data were processed in SDCimport software for initial filtering and multiple-time-around (MTA) disambiguation. MTA errors, corrected in this process, are the result of imprecise interpretations of received pulse time intervals and occur more frequently with higher pulse refresh rates. IMU and GPS data were used to integrate flightline information with the point cloud in Spatial Explorer software. The point data were calibrated at an incrementally precise scale of sensor movement and behavior, incorporating sensor velocity, roll, pitch, and yaw fluctuations throughout the survey. Points were classified in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) 2014 guidelines, using macros designed in Terrasolid software. Careful attention was given to the interpolation of the project's ground surface to compensate for inconsistent penetration through low vegetation as a function of the scan angle. Once classified, points underwent a geometric transformation and were converted from ellipsoidal heights to GEOID12B (Alaska) heights. Raster products were derived from the point cloud using ArcMap. The DTM was interpolated from all ground class returns using a mean binning method. The DSM was likewise interpolated from only the first returns for all classes. An intensity image was produced in ArcMap using mean binning.
- 2022-11-16 00:00:00 - Data were retrieved from the Alaska DGGS elevation portal then reorganized into cloud optimized geotiff format and ingested into the Data Access Viewer system. (Citation: Processed Digital Elevation Model)

6. Data Documentation
The EDMC Data Documentation Procedural Directive requires that NOAA data be well documented, specifies the use of ISO 19115 and related standards for documentation of new data, and provides links to resources and tools for metadata creation and validation.

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.
