As described in Section 7.5 of the ASPRS Positional Accuracy Standards for Digital Geospatial Data the horizontal errors in lidar data are largely a function of GNSS positional error, INS angular error, and flying altitude. Therefore lidar data collected with GNSS error of 0.05m and the IMU error of 0.03492 degrees at an altitude of 10,500 feet MSL; the expected radial horizontal positional error will be RMSEr = 0.367 US Survey Ft (11.2 cm). result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: Vertical Accuracy of the bare-earth lidar data was assessed and reported in accordance with the ASPRS Positional Accuracy Standards for Digital Geospatial Data; One hundred and sixty-nine (169) surveyed points were measured for the purpose of assessing the accuracy of the SRWMD LiDAR Gaps in North Central FL BAA-FY15 (95 NVA + 74 VVA). Both data sets, Lidar and Digital Elevation Models (DEMs) have been tested for their individual vertical accuracy levels. The Lidar was tested by using interpolation while the DEMs where tested by extracting the elevation of a pixel containing the checkpoint. All DEM Vertical accuracy results are reported in the DEM Metadata reports while this project wide Metadata file is reporting the vertical accuracy results from the the source Lidar. Required Vegetated Vertical Accuracy (VVA): 0.965 US Survey Ft. Required Non Vegetated Vertical Accuracy (NVA) : 0.643 US Survey Ft. This data set was tested to meet ASPRS Positional Accuracy Standards for Digital Geospatial Data (2014) for a 0.328 US Survey Ft RMSEz Vertical Accuracy Class. Actual NVA accuracy was found to be RMSEz = 0.219 US Survey Ft (6.8 cm) equating to +/-0.429 US Survey Ft (13.1 cm ) at 95% confidence level. Calculated Non-Vegetated Vertical Accuracy (NVA) of the Digital Elevation Model: 0.435 US Survey Ft (13.3 cm) RMSE is 6.8 cm Number of Check Points used to calculate the Reported (NVA) for the Digital Elevation Model: 95 Calculated (VVA) of the Digital Elevation Model: 0.932 US Survey Ft (28.4 cm) Number of Check Points used to calculate the Reported (VVA) for the Digital Elevation Model: 74 result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: The raw LAS data files included all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The raw point cloud is of good quality and data passes Fundamental Vertical Accuracy specifications.Void areas (i.e., areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Aerial LiDAR data covers the entire area of Interest intended for this project task. All LiDAR Point Cloud tiles show no edge artifacts or mismatches from tile to tile. Void areas (i.e., areas outside the project boundary but within the tiling scheme) are coded using a unique NODATA value. This value is identified in the appropriate location within the file header. Data cover the entire area specified for this project. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: Aerial LiDAR Acquisition: Aerial data collection was acquired, in Twelve (12) missions, using the Leica ALS80 SN# 8235 at an altitude of 6,100 feet MSL. This was to support a 4.0 ppm^2 LiDAR point cloud. Airborne GPS and IMU data was collected during the acquisition and supported by Leica GS15 & GPS 1200 base stations that occupied temporary monuments in conjunction with CORS stations, Data acquisition started December 10, 2015 and was complete January 14, 2016. Ground Control Survey: A survey was performed to support the acquisition of Light Detection and Ranging (LiDAR). The control network involved a total of 169 check points (95 NVA + 74 VVA). The points were a combination of the following ground cover classification: Bare Earth, Pavement, Sand, High Vegetation, Medium Vegetation, Low Vegetation. All field survey observations were conducted between August 10, 2015 and August 14, 2015 with Leica GPS 1200 equipment. dateTime: DateTime: 2016-01-18T00:00:00 processStep: (LI_ProcessStep) description: LiDAR Pre-processing: Airborne GPS and IMU data were merged to develop a Smooth Best Estimate of Trajectory (SBET) of the LiDAR system for each mission. 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 process was repeated interactively until residual errors between overlapping swaths, across all project lifts, was reduced to 2 cm or less. Raw data NVA were checked using surveyed check points. dateTime: DateTime: 2016-02-22T00:00:00 processStep: (LI_ProcessStep) description: RAW Data Processing: The Initial processing of the GPS data was processed using Inertial Explorer producing a solution file for each mission. Leica CloudPro software was then used to generate georeferenced laser returns into LAS 1.2 file format for each flight-line per each mission, this went through an initial Quality Control of the overlap between the flight-line swaths. dateTime: DateTime: 2016-02-29T00:00:00 processStep: (LI_ProcessStep) description: LiDAR Post-processing: The calibrated and controlled LiDAR swaths were processed using automatic point classification routines in TerraSolid 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. All classification tags are stored in the original swath files. After completion of classification and final QC approval, the NVA and VVA for the project are calculated. Sample areas for each land cover type present in the project were extracted and forwarded to the client, along with the results of the accuracy tests. Upon acceptance, the complete classified LiDAR swath files were delivered to the client. dateTime: DateTime: 2016-02-21T00:00:00 processStep: (LI_ProcessStep) description: LiDAR Classification: The calibrated LiDAR data went through automated classification routines and then manually edited and checked. The LiDAR point cloud data was classified into the following classes: 1-unclassified*, 2-ground, 7-low noise, 9-water, 10-buffer, 17-bridges, and 18-high noise dateTime: DateTime: 2016-01-08T00:00:00 processStep: (LI_ProcessStep) description: Hydro Breaklines: Hydro break lines were compiled in ArcMap using the LiDAR intensity data and surface terrain model of the entire project area. After the collection of hydro lines all features were conflated and validated for monotonicity and vertical variance, to ensure that no points were floating above ground. The hydro break lines were then embeded into the LiDAR surface and used to create a hydro enforced DEM. dateTime: DateTime: 2016-06-20T00:00:00 processStep: (LI_ProcessStep) description: Bare-Earth DEM Creation: Bare-Earth Digital Elevation Models (DEMs) were derived using the hydro break line and bare-earth (ground) LiDAR points, all DEMs were created with a grid spacing of 5 foot. The DEMs were cut to tiles of 5000 feet x 5000 feet index, provided by the US Geological Survey. dateTime: DateTime: 2016-06-29T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received DEM tif files at a 2.5 ft grid spacing from the SRWMD.
