        abstract:  Photoscience completed the original collection and classification of the multiple return LiDAR of Charleston County, South Carolina in the winter of 2006-2007. In 2009, Sanborn collected portions of Charleston County which were previously uncollected in 2006/7. In 2013, Dewberry was tasked with reviewing, updating and merging the original LiDAR products into one continuous data to include the 2006-2007 and 2009 separate projects. The 2006/2007 data was separated from the 2009 collected points in order to keep the 2 missions separate (collection dates, standards, data qualities, etc). The 2006-2007 data was removed by analyzing GPS time stamps of the LAS points in order to differentiate by collection year. The resulting LAS files left only the 2009 points which represent this project. The 2007 data already exists at OCM as part of a previous delivery. The nominal point spacing for this project is 1.4 meters. Dewberry used proprietary procedures to update and reclassify the LAS according to updated project specifications: 1-Unclassified, 2-Ground, 7-Noise, 8- Model Key Points, 9-Water, 10-Ignored Ground, 13- Points removed from bridges and culverts. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
        purpose:  The purpose of this LiDAR data was to produce high accuracy 3D elevation products, including tiled LiDAR in LAS 1.2 format, 3D breaklines, and ESRI grid raster format 10 ft cell size hydro flattened Digital Elevation Models (DEMs).

            nameOfMeasure:  Horizontal Positional Accuracy
            evaluationMethodDescription:  Lidar source compiled to meet 1 meter horizontal accuracy.; Quantitative Value: 1.0 meters, Test that produced the value: Dewberry does not perform independent horizontal accuracy testing on the LiDAR. LiDAR vendors perform calibrations on the LiDAR sensor and compare data to adjoining flight lines to ensure LiDAR meets the 1 meter horizontal accuracy standard at the 95% confidence level.

        report:  (DQ_AbsoluteExternalPositionalAccuracy)
            nameOfMeasure:  Vertical Positional Accuracy
            evaluationMethodDescription:  The vertical accuracy of the original LiDAR was tested by Dewberry in 2012 (or whenever we performed the original QAQC). Vertical Accuracy was not re-tested post updates performed in 2014. The vertical accuracy of the of the full LiDAR project was tested by Dewberry with independent survey checkpoints. The survey checkpoints were evenly distributed throughout the project area and are located in areas of bare earth and open terrain, high grass, pavement, brush and low trees, and forest. The vertical accuracy is tested by comparing survey checkpoints to a triangulated irregular network (TIN) that is created from the LiDAR ground points. Checkpoints are always compared to interpolated surfaces created from the LiDAR point cloud because it is unlikely that a survey checkpoint will be located at the location of a discrete LiDAR point. Checkpoints in open terrain were used to compute the Fundamental Vertical Accuracy (FVA). Project specifications required a FVA of 0.80 ft (24.5 cm) based on a RMSEz (0.41 ft/12.5 cm) x 1.9600. All checkpoints were used to compute the Consolidated Vertical Accuracy (CVA). Project specifications required a CVA of 1.19 ft (36.3 cm) based on the 95th percentile.; Quantitative Value: 0.185 meters, Test that produced the value: Calculated FVA to 0.61 ft (18.5 cm). Based on the vertical accuracy testing conducted by Dewberry, using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600 (Charleston County had a RMSEz of 9.25 cm+). The dataset for the Charleston County, SC LiDAR project satisfies the criteria: Lidar dataset tested 0.49 ft vertical accuracy at 95% confidence level in open terrain, based on RMSEz (0.33 ft) x 1.9600.

                description:  Raw LiDAR data (collected as Process Step 1) was processed to create a bare ground surface. Process included calibration of LiDAR data to remove systematic errors (utilizing Leica's ALS Processor software), adjustment of elevation data to control positions (utilizing TerraScan software for control comparisons and adjustments), and both automatic and manual editing to correctly classify ground and non-ground data (utilizing TerraScan and TerraModeler software). In addition, QC steps were performed before and after processing. QC steps included line-to-line vertical comparisons and coverage checks, and were performed with TerraScan and GeoCue software.

                description:  The ABGPS, IMU, and raw Leica ALS-50 LiDAR data are integrated into the LEICA ALS post processor software. The resultant file is in a LAS binary file format. The LAS file version 1.2 formats can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and GRS80 vertical datum. The date and time for each flight line can be determined using the Julian date and time.

                description:  The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters is applied as appropriate for the production of bare earth digital terrain models (DTMs). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.2 format. The header file for each dataset is complete as define by the LAS 1.2 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The LAS files do not include overlap. The data was classified as follows: 1-Unclassified, 2-Ground, 7-Noise,8- Model Key Points, 9-Water, 10-Ignored Ground, 13- Points removed from bridges and culverts.

The projection and all units remain the same. Additionally, Dewberry updated the precision of the lidar data from 2 decimal places to 3 decimal places. Dewberry also reviewed the LiDAR data and removed gross artifacts and anomalies by re-classifying the LiDAR points to more appropriate classes.

                description:  The NOAA Office for Coastal Management (OCM) received the files in laz format via hard drive from Dewberry. The data arrived referenced to the South Carolina State Plane (3900) and vertical reference to NAVD88 elevation in feet: 1. The data were converted from projected orthometric coordinates to geographic coordinates. 2. Vertical values were converted from NAVD88 to ellipsoidal values using Geoid09. 3. The 2006/2007 data was separated from the 2009 collected points in order to keep the 2 missions separate (collection dates, standards, data qualities, etc). The 2007 data was removed by analyzing time stamps for each point in the LAS files in order to differentiate collection year. The resulting LAS files showed only the 2009 points. The 2007 data already exists at OCM as part of a previous delivery. 4. The LAS data were stored as compressed LAZ data.

                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:
