Dataset Description: The OLC Baker County 3DEP 2017 LiDAR project called for the Planning, Acquisition, processing and derivative products of LIDAR data to be collected at a nominal pulse spacing (NPS) of 0.35 meters. Project specifications are based on the U.S. Geological Survey National Geospatial Program LIDAR Base Specification, Version 1.2. The data were developed based on a horizontal projection/datum of NAD83 (2011), meters and vertical datum of NAVD88 Geoid 12B, meters. LiDAR data was delivered in RAW flight line swath format, processed to create Classified LAS 1.4 Files formatted to individual 0.075 USGS quadrangle tiles, and corresponding hydroconditioned Bare Earth DEMs tiled to 7.5 USGS quadrangle schema, and Breaklines in ESRI File-Geodatabase format. Ground Conditions: LiDAR was collected while no snow was on the ground and rivers were at or below normal levels. In order to post process the LiDAR data to meet task order specifications, QSI established a total of 34 QA control points and 637 control points that were used to calibrate the LIDAR to known ground locations established throughout the OLC Baker County 3DEP 2017 project area. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Intensity Images, Breaklines and Raster DEM. The purpose of these lidar data was to produce high accuracy 3D hydro-flattened Digital Elevation Model (DEM) with a 1 meter cell size. These raw lidar point cloud data were used to create classified lidar LAS files, intensity images, 3D breaklines, hydro-flattened DEMs as necessary. credit: Quantum Spatial, Inc. flew the LiDAR and processed the data., Quantum Spatial, Inc.

Lidar ranging data were initially calibrated using previous best parameters for this instrument and aircraft. Relative calibration was evaluated using advanced plane-matching analysis and parameter corrections derived. This was repeated iteratively until residual errors between overlapping swaths, across all project lifts, was reduced to acceptable levels. Data were then block adjusted to match surveyed calibration control. Raw data NVA were checked using independently surveyed checkpoints. Swath overage points were identified and tagged within each swath file. dateTime: DateTime: 2017-10-01T00:00:00 processStep: (LI_ProcessStep) description: Lidar Post-Processing: The calibrated and controlled lidar swaths were processed using automatic point classification routines in proprietary software. These routines operate against the entire collection (all swaths, all lifts), eliminating character differences between files. Data were then distributed as virtual tiles to experienced lidar analysts for localized automatic classification, manual editing, and peer-based QC checks. Supervisory QC monitoring of work in progress and completed editing ensured consistency of classification character and adherence to project requirements across the entire project area. All classification tags are stored in the original swath files. After completion of classification and final QC approval, the NVA for the project is calculated. Sample areas for each land cover type present in the project area were extracted and forwarded to the U.S. Geological Survey, for Vegetated Vertical Accuracy (VVA) accuracy tests. Upon acceptance, the complete classified lidar swath files were delivered to the U.S. Geological Survey. dateTime: DateTime: 2017-10-01T00:00:00 processStep: (LI_ProcessStep) description: Classified LAS Processing: The bare earth surface is then manually reviewed to ensure correct classification on the Class 2 (Ground) points. After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through heads-up digitization. All ground (ASPRS Class 2) LiDAR data inside of the Lake Pond and Double Line Drain hydro flattening breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality. A buffer of 0.35 meters was also used around each hydro-flattened feature to classify these ground (ASPRS Class 2) points to Ignored ground (ASPRS Class 10). All Lake Pond Island and Double Line Drain Island features were checked to ensure that the ground (ASPRS Class 2) points were reclassified to the correct classification after the automated classification was completed. All overlap data was processed through automated functionality provided by TerraScan to classify the overlapping flight line data to approved classes by USGS. The overlap data was classified to Class 18 (High Noise) and Class 129 (Overlap Ground). These classes were created through automated processes only and were not verified for classification accuracy. Due to software limitations within TerraScan, these classes were used to trip the withheld bit within various software packages. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. ArcMap us used as a final check of the bare earth dataset. QSI proprietary software was then used to create the deliverable industry-standard LAS files. QSI proprietary software was used to perform final statistical analysis of the classes in the LAS files, on a per tile level to verify final classification metrics and full LAS header information. dateTime: DateTime: 2017-10-01T00:00:00 processStep: (LI_ProcessStep) description: Hydro Flattening Breakline Processing: Class 2 LiDAR was used to create a bare earth surface model. Proprietary software utilized rasters created within Bentley Microstation to auto-generate breaklines of inland streams and rivers with a 30 meter nominal width which were then manually inspected and digitized. Breaklines for Lakes with surface area greater than 2 acres were generated using heads-up digitization. Elevation values were assigned to all Inland Ponds and Lakes within ESRI ArcMap; Inland Pond and Lake Islands, Inland Stream and River Islands were assigned elevation values from within ESRI ArcMap. All ground (ASPRS Class 2) LiDAR data inside of the collected inland breaklines were then classified to water (ASPRS Class 9) using TerraScan macro functionality. A buffer of 0.35 meters was also used around each hydro-flattened stream. These points were moved from ground (ASPRS Class 2) to Ignored Ground (ASPRS Class 10). The breakline files were then translated to ESRI File-Geodatabase format using ESRI conversion tools. dateTime: DateTime: 2017-10-01T00:00:00 processStep: (LI_ProcessStep) description: Hydro Flattened Raster DEM Process: Class 2 LiDAR in conjunction with the hydro breaklines were used to create a hydro-flattened DEM. Using automated scripting routines within Bentley Microstation, ascii files were created for each tile. The ascii files are then mosaicked together in ArcMap and reviewed for surface anomalies. dateTime: DateTime: 2017-10-01T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received 1,838 laz files from the Oregon Lidar Consortium/ DOGAMI. The data were in UTM Zone 11N (NAD83 2011) coordinates in meters and NAVD88 (Geoid12b) elevations in meters. The data were classified as: 1 - Unclassified, 2 - Ground, 7 - Low Noise, 9 - Water, 10 - Ignored Ground, 17 - Bridge Decks, 18 - High Noise. OCM processed all classifications of points to the Digital Coast Data Access Viewer (DAV). Classes available on the DAV are: 1, 2, 3, 7, 9, 10, 17, 18. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges. 2. Internal OCM scripts were run on the laz files to convert from orthometric (NAVD88) elevations to ellipsoid elevations using the Geoid12b model, to convert from UTM Zone 11N (NAD83 2011) coordinates in meters to geographic coordinates, to assign the geokeys, to sort the data by gps time and zip the data to database and to http. processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) description: Source Contribution: This data source was used to populate the lidar point cloud data. sourceCitation: (CI_Citation) title: Lidar RAW Data for OLC Baker County 3DEP 2017 date: (CI_Date) date: 2018-01-15 dateType: (CI_DateTypeCode) publication citedResponsibleParty: (CI_ResponsibleParty) organisationName: Quantum Spatial, Inc. role: (CI_RoleCode) originator sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimePeriod: beginPosition: 2017-09-26 endPosition: 2017-09-30 source: (LI_Source) description: Source Contribution: This data source was used (along with the airborne GPS/IMU Data) to aid in the georeferencing of the lidar point cloud data. sourceCitation: (CI_Citation) title: Survey Report of LiDAR Ground Control Points: OLC Baker County 3DEP 2017 LiDAR date: (CI_Date) date: 2018-01-15 dateType: (CI_DateTypeCode) publication citedResponsibleParty: (CI_ResponsibleParty) organisationName: Quantum Spatial, Inc. role: (CI_RoleCode) originator sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2017 source: (LI_Source) description: Source Contribution: This data source was used (along with the lidar intensity imagery) to QC and vertically adjust the lidar point cloud data. scaleDenominator: (MD_RepresentativeFraction) denominator: 50 sourceCitation: (CI_Citation) title: Survey Report of LiDAR Quality Control Points: OLC Baker County 3DEP 2017 LiDAR date: (CI_Date) date: 2018-01-15 dateType: (CI_DateTypeCode) publication citedResponsibleParty: (CI_ResponsibleParty) organisationName: Quantum Spatial, Inc. role: (CI_RoleCode) originator sourceExtent: (EX_Extent) temporalElement: (EX_TemporalExtent) extent: TimeInstant: timePosition: 2017 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.
