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, however, derived products may be less accurate in extreme terrain and dense vegetation due to a lesser number of points defining the bare-earth in these areas. Questions regarding data accuracy can be best answered by AeroMetric/Quantum Spatial (Anchorage, Alaska) staff. The dataset was provided to us in LAS 1.1 format (not in LAS 1.3 format as noted in the delivery report.) result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: Data products collected were acquired at or below 600 meters above mean terrain (AMT) and have a horizontal accuracy of 0.4 meters (per manufacturer's system specifications) with a nominal point spacing of 0.74 meters. No direct testing of the horizontal accuracy was feasible given this dataset. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: The bare-earth classified LiDAR data were compared to Rodney P. Kinney and Associates check points throughout the project area. A statistical summary of the elevation differences was completed. The data have a vertical accuracy of 11 cm RMSE at the 95% confidence level. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: DGGS staff performed visual qualitative assessment to ensure data completeness. There are no void areas or missing data. Users should note that this dataset was acquired in 2005 and subsequently migrated to more modern specifications in 2013. Questions regarding data quality and completeness can be best answered by AeroMetric/Quantum Spatial (Anchorage, Alaska) staff. In addition to the classified point cloud data and delivery report provided by this release, AeroMetric also provided to DGGS: trajectory values, unclassified point cloud data, and a statistical summary of the elevation differences between LiDAR values and the ground survey points that were collected by Rodney P. Kinney and Associates) result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Quality control and quality assurance ground survey points were collected by Rodney P. Kinney and Associates and supplied to AeroMetric. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: Collection - The raw LiDAR data points were captured using AeroMetric's twin-engine Cessna equipped with a OPTECH 30/70 ALTM 70 kHz LiDAR acquisition system. The system includes differential GPS (DGPS) and inertial navigation systems (INS) to provide the necessary trajectory accuracy. dateTime: DateTime: 2005-01-01T00:00:00 processStep: (LI_ProcessStep) description: Processing - The airborne trajectory solution was processed in Applanix's POSPac v. 4.4, which first computes a 2 Hz Post Processed Kinematic (PPK) DGPS trajectory, then integrates the 200 Hz inertial measurement unit data for a final smoothed best estimate of trajectory (SBET). This SBET is then integrated with the LiDAR pulse data, utilizing Optech's REALM software, for a final x,y,z 'point cloud' dataset in industry standard LAS (LiDAR Accuracy Standard) format in the NAD83, Universal Transverse Mercator (UTM), Zone 4 Meters coordinate system with ellipsoidal heights. dateTime: DateTime: 2006-01-01T00:00:00 processStep: (LI_ProcessStep) description: Migration and calibration - For this delivery, AeroMetric gathered the necessary data from the Unalakleet archive drive. Using GeoCue (V2012.1.27.5), AeroMetric converted the LAS swath data to NAVD88 GEOID09, NAD83 UTM Zone 4. The archived LAS swath data lacked return and scan angle information. Individual points were classified based on return number. Using proprietary in-house software, AeroMetric was able to use these classifications and timestamps to calculate the point return fields. Polygons were digitized along flight line edges to re-class the geometrically unreliable points near the extreme edge of the swath to help with calibration. An in-situ calibration was performed using the data collect for this project. The dataset was classified in each line separately for ground and other common features between lines, such as building roofs. This dataset was processed in TerraSolid's TerraMatch (Version 11.001) to compute corrections for roll, pitch, heading, and mirror scale. These corrections are applied in order to minimize discrepancies between flight lines. dateTime: DateTime: 2013-01-01T00:00:00 processStep: (LI_ProcessStep) description: Classification - AeroMetric preformed 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. This step was followed by manual classification of any data which appeared to be poorly classified using the automated methods. Breaklines were digitized along coast and water bodies that met project standards listed above. dateTime: DateTime: 2013-01-01T00:00:00 processStep: (LI_ProcessStep) description: Verification - Rodney P. Kinney (RPK) and Associates provided AeroMetric with Post Processed Kinematic (PPK) Quality Assurance and Quality Control (QAQC) data, to check the vertical accuracy of these LiDAR data. The 2006 control file had to be translated by AeroMetric from GEOID99 to GEOID09. A comparison between the QAQC and the LiDAR point data were made using TerraScan, to determine any vertical bias in the data. An adjustment of 0.21 meters was applied to the LiDAR data in order to match the provided QAQC data. dateTime: DateTime: 2013-01-01T00:00:00 processStep: (LI_ProcessStep) description: Classified LAS 1.1 files - AeroMetric created classified LAS 1.1 files using the client provided tiling scheme. The points within each tile are sorted sequentially in order of acquisition, and have adjusted GPS timestamps. Note: that the Acquisition and Processing Report provided by AeroMetric incorrectly cites the deliverable format as LAS 1.3. dateTime: DateTime: 2013-01-01T00:00:00 processStep: (LI_ProcessStep) description: File compression - LAS files were compressed to LAZ format to facilitate online distribution dateTime: DateTime: 2014-01-01T00:00:00 processStep: (LI_ProcessStep) description: The lidar files were received by the NOAA Office for Coastal Management for incorporation into the NOAA Digital Coast. The data consisted of 19 lidar files. The data were in LAS format 1.1 and were in UTM, Zone 4, NAD83, meters coordinates. The data were in NAVD88 (Geoid09), meters vertical units. The classifications of the data are: 1 (Unclassified), 2 (Ground), 3 (Low Vegetation), 4 (Medium Vegetation), 5 (High Vegetation), 6 (Buildings), 9 (Water), 10 (Ignored Ground, breakline proximity). For Digital Coast data storage and provisioning, the NOAA OCM performed the following processing: 1. The data were reviewed for any elevation outliers. 2. The data were converted from UTM, Zone 4 coordinates to geographic coordinates. 3. The data were converted from NAVD88 elevations to ellipsoid elevations using Geoid09. 4. The data were zipped to laz format. dateTime: DateTime: 2014-05-13T00:00:00 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID12B) meters, using the GEOID12B grids provided by the National Geodetic Survey. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org) Processing notes: dateTime: DateTime: 2023-07-01T05:11:21 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor return to top metadataConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
