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
Lidar-derived elevation data for the Utqiagvik-Atqasuk region, Alaska, collected August 2019, Raw Data File 2022-10, provides classified point cloud, digital terrain model (DTM), surface model (DSM), and intensity model data for the communities of Utqiagvik and Atqasuk and surrounding areas. The data were collected in support of the Alaska Strategic Transportation and Resources (ASTAR) program for the purpose of investigating the potential for future road infrastructure connecting the communities. Aerial lidar data were collected between August 19 and 23, 2019, and subsequently processed using a suite of geospatial processing software. These products are released as a Raw Data File with an open end-user license. All files can be downloaded from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30870).
The NOAA Office for Coastal Management (OCM) downloaded this data set from this AK DGGS site:
These files were processed to make the data available for custom and bulk download from the NOAA Digital Coast Data Access Viewer (DAV) . The total number of files downloaded and processed was 1.
In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
Notes: Only a maximum of 4000 characters will be included.

Data were collected by the Alaska Division of Geological and Geophysical Surveys (AK DGGS). OCM downloaded the data from the Alaska DGGS Elevation Portal and processed the data to be available for custom and bulk download from the NOAA Digital Coast Data Access Viewer (DAV).
- 2019-09-23 00:00:00 - Aerial photogrammetric survey - DGGS used a Riegl VUX1-LR laser scanner integrated with a global navigation satellite system (GNSS) and Northrop Grumman LN-200C inertial measurement unit (IMU). The lidar integration system was designed by Phoenix LiDAR Systems. The sensor can collect up to 820,000 points per second over a distance of 150 m. This survey was flown with a pulse refresh rate of 400,000 pulses per second, at a scan rate between 80 and 220 lines per second. This survey was flown with an average elevation of 200 m above ground level and a ground speed of approximately 30 m/s with a fixed-wing configuration, using a Cessna 180. The scan angle was set from 80 to 280 degrees. The total area surveyed was approximately 1,595 km^2. Aerial lidar was collected between August 19 and 23, 2019. Seven flightlines collected on the evening of August 22 yielded too large a file for our software to process and the points from those lines are not represented in our final product.
- 2018-09-01 00:00:00 - Ground survey - Ground survey points from an UMIAQ, LLC, collection in September 2018, were used as control and checkpoint data for this dataset. These survey data were originally gathered in support of a USGS 3DEP funded lidar project, headed by Quantum Spatial (now NV5 Geospatial).
- 2022-01-01 00:00:00 - Photogrammetric 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. Inertial Measurement Unit (IMU) and Global Navigation Satellite System (GNSS) data were processed in Inertial Explorer and 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 American Society for Photogrammetry and Remote Sensing (ASPRS) 2014 guidelines, using macros designed in Terrasolid software. Once classified, points underwent a geometric transformation and were converted from ellipsoidal heights to GEOID12B (Alaska) orthometric heights. Raster products were derived from the point cloud using ArcGIS Pro. The DTM was interpolated from all ground class returns using a TIN-based method. The DSM was likewise interpolated from only the first return points. An intensity image was also produced in ArcGIS Pro, using closest-to-mean binning.
- 2022-09-28 00:00:00 - The NOAA Office for Coastal Management (OCM) downloaded 1 raster DEM file in GeoTiff format from the Alaska DGGS Elevation Portal. The data were in UTM Zone 4 NAD83 (2011), meters coordinates and NAVD88 (Geoid12B) elevations in meters. The bare earth raster file was at a 1 meter grid spacing. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Used internal an script to assign the EPSG codes (Horizontal EPSG: 6333 and Vertical EPSG: 5703) to the GeoTiff formatted files. 2. Copied the files to https.

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.
