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
These data were collected by Woolpert using a Leica Hawkeye4X system. Data for Niihau were acquired from September 8, 2021 through September 26, 2021.
The data includes raster topobathy data in geotiff format created from ground (2) and bathymetric point (40) lidar point values.
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.)

Notes: The name of the Person of the most recent Support Role of type "Metadata Contact" is used. The support role must be in effect.
Notes: The name of the Organization of the most recent Support Role of type "Metadata Contact" is used. This field is required if applicable.
3. Responsible Party for Data Management
Program Managers, or their designee, shall be responsible for assuring the proper management of the data produced by their Program. Please indicate the responsible party below.
Notes: The name of the Person of the most recent Support Role of type "Data Steward" is used. The support role must be in effect.
4. Resources
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.

Process Steps:
- 2024-01-17 00:00:00 - Woolpert acquired, calibrated, and performed the refraction correction of the lidar data. Light travels at different speeds in air versus water and its direction of travel or angle is changed or refracted when entering the water column. The refraction correction process corrects for this difference by adjusting the depth (distance traveled) and horizontal position (change of angle/direction) of the lidar data acquired within water. Relative accuracy of the swaths compared to overlapping and adjacent swaths was verified through the use of Delta-Z (DZ) orthos created in LASTools software. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths. The NovAtel software was utilized for GPS and inertial processing, Data were processed to an initial LAS format using the Leica Lidar Survey Studio software. Algorithms in TerraScan was used to create the initial ground surface. All lidar data was peer-reviewed. QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. LASTools was used to update LAS header information, including all projection and coordinate reference system information. The final lidar data is in LAS format 1.4 and point data record format 6. Data were processed in NAD83 (PA11) horizontal and vertical datum. The National Oceanic and Atmospheric Administration (NOAA) received files in laz format. Data for Niihau, HI was delivered in UTM Zone 4 coordinates and ellipsoid elevations in meters. Horizontal Datum-NAD83 (PA11) epoch: 2010.0 Projection-UTM Zone 4 North Horizontal Units-meters Vertical Datum-NAD83 (PA11) Ellipsoid height Vertical Units-meters The final classification scheme for all data delivered to NOAA is as follows: 1-Unclassified 2-Ground 7-Low Noise 9-Topo Water Surface 18-High Noise 40-Bathymetric Point 41-Bathymetric Water Surface 42-Synthetic Derived Water Surface 43-Submerged Object 44-International Hydrographic Organization (IHO) S-57 Object 64-Submerged Aquatic Vegetation 65-Bathymetric Bottom Temporal Changes
- 2021-10-01 00:00:00 - The lidar data is referenced to the NAD83 (PA11) ellipsoid. The lidar data in ellipsoid heights was used to create the final topobathymetric DEMs in ellipsoid heights. Lidar data were used to generate a raster in geotiff format with 1 meter pixel resolution for the entire area. The raster was then clipped to the tile grid and named according to project specifications to result in tiled topobathymetric DEMs. Bathy void polygons represent bathymetric areas with no bathymetric bottom returns and accompany the DEMs. Void polygon creation is described in the final project report and the void polygon metadata. A confidence layer has been created and provided to NOAA as part of the deliverables. Except where there are not enough lidar data points in a pixel to calculate a standard deviation value, the confidence layer is a raster product in geotiff format with 1 meter square pixels. The confidence layer provides a standard deviation value for every pixel by calculating the standard deviation of all ground and/or submerged topography lidar points that are located within a single pixel. The confidence layer pixels align to the pixels in the topobathy DEMs. The confidence layer can be displayed by unique values or classified into desired bins/ranges for analysis over larger areas.

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.
Missing/invalid information:
- 1.7. Data collection method(s)
- 3.1. Responsible Party for Data Management
- 5.2. Quality control procedures employed
- 7.1.1. If data are not available or has limitations, has a Waiver been filed?
- 7.4. Approximate delay between data collection and dissemination

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.
None
