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
In June 2014, WSI, a Quantum Spatial Inc. (QSI) company, was contracted by the Puget Sound LiDAR Consortium (PSLC) to collect Light Detection and Ranging (LiDAR) data for the Washington Department of Natural Resources (WA DNR) Lands in western Washington. Data were collected to aid the WA DNR in assessing the topographic and geophysical properties of the study area. Acquisition of the three separate areas were completed between December 2014 and March 2015, each area was delivered and will be available separately.
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.)

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:
- 2014-12-31 00:00:00 - The LiDAR survey was accomplished using a Leica ALS70 and a Leica ALS80 system mounted in a Cessna Grand Caravan. The report associated with this project summarizes the settings used to yield an average pulse density of 8 pulses/m^2 over the WA DNR Lands project area; figure 5 shows acquisition flightlines. The Leica ALS70 and ALS80 systems can record unlimited measurements (returns) per pulse, but typically do not record more than five returns per pulse. It is not uncommon for some types of surfaces (e.g., dense vegetation or water) to return fewer pulses to the LiDAR sensor than the laser originally emitted. The discrepancy between first return and overall delivered density will vary depending on terrain, land cover, and the prevalence of water bodies. All discernible laser returns were processed for the output dataset.
- 2014-06-01 00:00:00 - 1. Resolve kinematic corrections for aircraft position data using kinematic aircraft GPS and static ground GPS data. Develop a smoothed best estimate of trajectory (SBET) file that blends post-processed aircraft position with sensor head position and attitude recorded throughout the survey. 2. Calculate laser point position by associating SBET position to each laser point return time, scan angle, intensity, etc. Create raw laser point cloud data for the entire survey in *.las (ASPRS v. 1.2) format. Convert data to orthometric elevations by applying a geoid correction. 3. Import raw laser points into manageable blocks (less than 500 MB) to perform manual relative accuracy calibration and filter erroneous points. Classify ground points for individual flight lines. 4. Using ground classified points per each flight line, test the relative accuracy. Perform automated line-to-line calibrations for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Calculate calibrations on ground classified points from paired flight lines and apply results to all points in a flight line. Use every flight line for relative accuracy calibration. 5. Classify resulting data to ground and other client designated ASPRS classifications (Table Assess statistical absolute accuracy via direct comparisons of ground classified points to ground control survey data. 6. Generate bare earth models as triangulated surfaces. Generate highest hit models as a surface expression of all classified points. Export all surface models as ESRI GRIDs in EDRAS Imagine (.img) format at a 1 meter pixel resolution. 7. Correct intensity values for variability and export intensity images as GeoTIFFs at a 0.5-meter pixel resolution.
- 2016-03-05 00:00:00 - The NOAA Office for Coastal Management (OCM) downloaded topographic files in .laz format from PSLC. The files contained lidar elevation, intensity, return number, class, scan angle and GPS time measurements. The data were received in Washington State Plane South Zone 4602, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03, and from feet to meters. 2. The las files were converted from a Projected Coordinate System (WA SP South) to a Geographic Coordinate system (NAD83), converting from feet to decimal degrees. 3. Erroneous points were removed and class 11 points were reclassified to class 12 (overlap) to hold to the NOAA OCM classification scheme. 4. Filenames were altered with the addition of which WA DNR Land the tile resides. At the moment of publication of this metadata, P3 is not available publicly and therefore will not be available with this Digital Coast project.

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.
