This LiDAR dataset is a survey of Coastal California. The project area consists of approximately 2616 square miles. The project design of the LiDAR data acquisition was developed to support a nominal post spacing of 1 meter. Fugro EarthData, Inc. acquired 1546 flight lines in 108 lifts between October 2009 and August 2011. LiDAR data collection was performed with two Piper Navajo twin engine aircrafts, utilizing a Leica ALS60 MPiA sensor; collecting multiple return x, y, and z as well as intensity data. The bare-earth lidar data was used to create hydro-flattened DEMs (Digital Elevation Models) available for download from the NOAA OCM Digital Coast.

One GPS base station was also running at the operation airport and was recording data at 1 Hz. The airborne GPS data was post-processed in DGPS mode together with the base station data to provide high accuracy aircraft positions. The GPS trajectory then was combined with the IMU data using loosely coupled approach to yield high accuracy aircraft positions and attitude angles. Then the LiDAR data was processed using the aircraft trajectory and raw LiDAR data. After boresighting the LiDAR data, the ground control points were measured against the LiDAR data by technicians using TerraScan and proprietary software and the LiDAR data was adjusted vertically to the ground control. Independent ground control check points were used to ensure vertical accuracy of the data. The horizontal datum for the control was the North American Datum of 1983 (NAD83, NSRS2007).The vertical datum was the North American Vertical Datum of 1988 (NAVD88). The vertical datum was realized through the use of the published/calculated ellipsoidal heights of the base station to process the aircraft trajectory and then later applying the GEOID09 model to the processed LiDAR data to obtain orthometric heights. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: The minimum expected horizontal accuracy was tested to meet or exceed the National Standard for Spatial Data Accuracy (NSSDA). Horizontal accuracy is 50 cm RMSE or better. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: The minimum expected vertical accuracy was tested to meet or exceed the National Standard for Spatial Data Accuracy (NSSDA). When compared to GPS survey grade points in generally flat, non-vegetated areas, at least 95% of the positions had an error less than or equal to 9.4 cm (equivalent to root mean square error (rmse) of 4.8 cm if errors were normally distributed). result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Measure evaluationMethodDescription: Cloud Cover: 0 result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: The following methods are used to ensure LiDAR data accuracy: 1) Use of a ground control network utilizing GPS survey techniques; 2) Use of airborne GPS and IMU in conjunction with the acquisition of LiDAR; and 3) Measurement of quality control ground survey points within the finished product. The following software is used for the validation: 1) Terrascan and 2) Fugro EarthData Proprietary Software. result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Compliance with the accuracy standard was ensured by the collection of ground control and the establishment of a GPS base station at the operation airport. The following checks were performed: 1) The LiDAR data accuracy was validated by performing a full boresight adjustment and then checking it against the ground control prior to generating a digital terrain model (DTM) or other products. 2) LiDAR elevation data was validated through an inspection of edge matching and visual inspection for quality (artifact removal). result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: The hydro-enforced bare earth DEM was generated using the bare earth points, as well as the 3D hydro breaklines. The following is a step-by-step breakdown of the process: 1) After the deliverable LAS files were generated for the entire project area and QC'ed, and the 3D breaklines were collected and QC'ed, they were used to produce the hydro-enforced bare earth DEM. The bare earth points that fell within 1*NPS along the hydro breaklines were taken out of from Ground class so that these points were excluded from the DEM generation process. This process was done in batch mode using Fugro EarthData's proprietary software. 2) Inland ponds and lakes, inland streams and rivers, and tidal water bodies were hydro-flattened within the DEM. Hydro-flattening was applied to water impoundments, natural or man-made, larger than ~2 acres in area (inland ponds and lakes larger than 1 acre were collected for the 500 meter corridor); to streams nominally wider than 100' (inland streams and rivers wider than 15 meters were collected for the 500 meter corridor); and to tidal waters bodies, which includes any significant water body that is affected by tidal variations. 3) The hydro-flattened bare earth DEM generated in initial grid format was then clipped to the approved DEM product boundary. 4) After the hydro-flattened bare earth DEM was clipped to the boundary, the technician checked the tiles to ensure that the grid spacing met specifications and checked the surface to ensure proper hydro-flattening. The data was cut to the approved tile layout. The entire data set was checked for complete project coverage and to ensure it was free of anomalies. 5) The hydro-flattened bare earth DEM was then converted to the delivery ESRI Grid format. dateTime: DateTime: 2011-11-15T00:00:00 source: (LI_Source) description: Source Contribution: Fugro EarthData, Inc. collected ALS60-derived LiDAR over Coastal California with a 1 meter, nominal post spacing using two Piper Navajo twin engine aircrafts. The collection for the entire project area was accomplished between October 2009 and August 2011; 1,546 flight lines were acquired in 108 lifts. The lines were flown at an average of 6,244 feet above mean terrain using a pulse rate of 121,300 pulses per second. The collection was performed using Leica ALS60 MPiA LiDAR systems, serial numbers 113 and 142. | Type of Source Media: External hard drive sourceCitation: (CI_Citation) title: Aerial Acquisition of Coastal California LiDAR date: (CI_Date) date: 2011-08-04 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimePeriod: beginPosition: 2009-10-15 endPosition: 2011-08-02 source: (LI_Source) description: Source Contribution: Fugro EarthData, Inc. utilized commercial software as well as proprietary software for automatic filtering of LiDAR data to identify and re-classify elevation points falling on vegetation, building, and other above ground structures into separate data layers. The parameters used in the process were customized for each terrain type to obtain optimum results. Once the automated filtering was completed, the files were run through a visual inspection to ensure that the filtering was not too aggressive or not aggressive enough. In cases where the filtering was too aggressive and important terrain features were filtered out, the data was either run through a different filter or was corrected during the manual filtering process. Interactive editing was then completed in 3D visualization software which also provides manual and automatic point classification tools using commercial and proprietary software for the process. Vegetation and artifacts remaining after automatic data post-processing were reclassified manually through interactive editing. The hard edges of ground features that were automatically filtered out during the automatic filtering process were brought back into ground class during manual editing. The technician then reviewed the LiDAR points with color shaded TINs for anomalies in ground class during interactive filtering. Upon the completion of bare earth filtering and peer review process, the classified LiDAR point cloud work tiles went through a water classification routine based on the collected water polygons. Upon the completion of finalization of the classified LiDAR point cloud work tiles, the topographic LiDAR classified point cloud data that was produced under the JALBTCX and NOAA OCM programs was merged. The final classified LiDAR point data were packaged to NAD83 (NSRS2007), UTM zones 10 and 11 north, meters; NAVD88, meters, using GEOID09 and cut to the approved tile layout and project boundary in LAS format. | Type of Source Media: Internal net sourceCitation: (CI_Citation) title: Coastal California LiDAR; Classified LiDAR Point Cloud Data date: (CI_Date) date: 2011-10-20 dateType: (CI_DateTypeCode) publication sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2011-10-20 source: (LI_Source) description: Source Contribution: TerraSurv under contract to Fugro EarthData, Inc. successfully established ground control for Coastal California LiDAR.
