All data was collected during ideal conditions (rivers at or below mean level, leaf off, etc.). For this collect two sensors were used: The Leica ALS-50 (High Relief Collection) and Optech 2050 (High and Low Relief Collection). LiDAR calibrations were performed to determine and therefore eliminate systematic biases that occur between the the two sensors. Once the biases were determined they were modeled out. The Leica ALS-50 produced an average point spacing of 1.4 meters. The Optech 2050 produced an average point spacing of 1.3 meters. All points are classified as Class 2 (Ground) which includes water points and any possibly remaining artifacts. Leica ALS-50 LiDAR Acquisition Paramters: Avg.

The project did not meet the specifications for vertical accuracy or data voids. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: The LiDAR data was compiled to meet a 1 meter horizontal accuracy. The calibration of the LiDAR sensor itself and the calibration process of the data produced by this sensor ensure that this accuracy is met. ; Quantitative Value: 1 meters, Test that produced the value: Value stated as RMSE @ 95% confidence in meters result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: The LiDAR data was tested by Sanborn for vertical accuracy. Sanborn collected a total of 60 ground control points for use in verifying the vertical accuracy of the classified LiDAR data in North Puget Sound. Only 45 ground control points proved valid. These points were tested against the classified LiDAR data. ; Quantitative Value: 0.55 meters, Test that produced the value: RMSEz in meters result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: Datasets contain complete coverage of tiles except where previously discussed. result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Deliverables were tested by Sanborn for vertical accuracy and consistency. There are two small unsurveyed areas near the North Fork Nooksack River. There are three areas of sparse returns located along Finney Creek south of Concrete, near Marblemount and along the Skagit River near Ross Dam. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: Final post-processing of LiDAR data involves several steps. The airborne GPS data was post-processed using Waypoint's GravNAVTM software (version 7.5). A fixed-bias carrier phase solution was computed in both the forward and reverse chronological directions. The data was processed for both base stations and combined. In the event that the solution worsened as a result of the combination of both solutions the best of both solutions was used to yield more accurate data. The GPS trajectory was combined with the raw IMU data and post-processed using Applanix Inc.'s POSPROC (version 4.3) Kalman Filtering software. This results in a two-fold improvement in the attitude accuracies over the real-time INS data. The best estimated trajectory (BET) and refined attitude data are then reintroduced into the LEICA ALS post processor or REALM Survey Suite OPTECH to compute the laser point-positions. The trajectory is then combined with the attitude data and laser range measurements to produce the 3-dimensional coordinates of the mass points. All return values are produced within ALS Post Processing software or REALM Survey Suite OPTECH software. The multi-return information minus the last return provides a useful depiction of the "canopy" within the project area. The last return is further processed to obtain the "Bare Earth Dataset" as a deliverable. All LiDAR data is processed using the binary LAS format 1.0 file format. LiDAR filtering was accomplished using TerraSolid, TerraScan LiDAR processing and modeling software. The filtering process reclassifies all the data into classes within the LAS formatted file based scheme set using the LAS format 1.0 specifications or by the client. Once the data is classified, the entire data set is reviewed and manually edited for anomalies that are outside the required guidelines of the product specification or contract guidelines, whichever apply. The coordinate and datum transformations were then applied to the data set to reflect the required deliverable projection, coordinate and datum systems as provided in the contract. The final data is in State Plane Washington North Coordinate System with the horizontal and vertical units being in feet. dateTime: DateTime: 2006-01-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received topographic file in ASCII .XYZ format. The files contained lidar elevation measurements. The data were received in Washington State Plane North Zone 4601, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid99 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The ASCII .XYZ files were converted to LAS version 1.1 using Global Mapper. 2. All points in Class 0 (Never Classified) were changed to Class 2 (Ground). This includes water points. 3. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid99. 4. The topographic las files were converted from a Projected Coordinate System (WA SP North) to a Geographic Coordinate system (GCS). 5. The topographic las files' vertical units were converted from feet to meters. 6. The topographic las files' horizontal units were converted from feet to decimal degrees. dateTime: DateTime: 2013-01-01T00:00:00 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 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: 2023-07-01T05:58:25 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
