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
This delivery contains point cloud data in LAS 1.2 format classified in the following manner:
Class 1: Unclassified
Class 2: Ground
Class 3: Low Vegetation
Class 6: Buildings
Class 7: Noise
Class 8: Ground Model Keypoints
Class 9: Water
Class 10: Breakline Proximity
The following are the collection parameters and equipment used to create these data sets:
Aircraft: Piper Navajo (812TB)
LiDAR System: Leica ALS70
Approximate Collection Altitude (Above Mean Terrain): 1070 meters
Ground Speed: 150 kts
Pulse Rate Frequency: 245 kHz
Mirror Scan Frequency: 60 Hz
Scan Angle (+/-): 15 degrees
Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas. Classified data sets such as this one may have varying posting due to some pulses not reaching the ground.
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 1804. 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.
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.)

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.

The data were collected for UAF/GINA and made available on the AK DGGS Elevation Portal (https://elevation.alaska.gov/). The NOAA Office for Coastal Management (OCM) downloaded the data from this site to make the data available for custom downloads from the NOAA Digital Coast Data Access Viewer and for bulk downloads from the AWS S3 bucket.
- 2013-08-01 00:00:00 - Created a smoothed-best estimated trajectory (SBET) of the sensor at a rate of 200 Hz, by integrating the airborne GPS and IMU data The basis of the GPS coordinates were two dual frequency GPS receivers, collecting data at a rate of 2 Hz operated by Aero-Metric during the acquisition phase of this project, and were referenced to to NAD83 (CORS96) ellipsoid heights.
- 2013-08-18 00:00:00 - Integrated SBET and raw laser data to produce point cloud data in LAS 1.2 format for each flight line.
- 2013-08-22 00:00:00 - Processed data calibration: An in-situ calibration was performed using the data collect for this project. The data was classified in each line separately for ground and other common features between lines, such as building roofs. This data was processed in TerraMatch 11.001 (TerraSolid, Ltd.), to compute corrections for roll, pitch, heading, and mirror scale. These corrections are applied in order to minimize discrepancies between flight lines.
- 2013-08-24 00:00:00 - Automated classification of the bare-earth data from the LiDAR point cloud using a series of algorithms customized for the types of terrain encountered in the project.
- 2013-10-17 00:00:00 - Manually classified any data which appears to be improperly classified using the automated methods.
- 2013-07-19 00:00:00 - Created classified point cloud data, in LAS 1.2 format.
- 2022-11-14 00:00:00 - The NOAA Office for Coastal Management (OCM) downloaded 1804 laz files from the Alaska Division of Geological and Geophysical Surveys Elevation Portal (https://elevation.alaska.gov/). The files contained classified elevation and intensity measurements for the 2013 Coastal Plain project. The data were in AK State Plane Zone 4 NAD83 (2011), meters coordinates and NAVD88 (GEOID12A) elevations in meters. The data had the following classifications: 1 - Unclassified, 2 - Ground, 3- Low Vegetation, 6 - Buildings, 7 - Noise, 8 - Model Key Point, 9 - Water, 10 - Breakline Proximity. OCM processed all points to the Digital Coast Data Access Viewer (DAV). The metadata and the report said that there were Class 13 points (Bridges), but the OCM internal script to check the point classifications, resulted in 0 points with that classification. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Internal OCM scripts were run to check the number of points by classification and by flight ID and the gps and intensity ranges. 2. Internal OCM scripts were run on the laz files to convert from AK State Plane Zone 4 NAD83 (2011) meters coordinates to geographic coordinates, to convert from NAVD88 elevations to ellipsoid elevations using the GEOID12A model, to assign the geokeys, to sort the data by gps time and zip the data to database and to the AWS S3 bucket.

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.
