information
The LiDAR data acquisition was executed in five sessions, on March 15, 16 & 17, 2006, using a Leica ALS50 LiDAR System. Specific details about the ALS50 system are included in Section 4 of this report.
The three airborne GPS (ABGPS) base stations supporting the LiDAR acquisition were located on 1) a NGS SAC monumented control point inside Bush Field Airport (AGS), point AA2799, 2) a point inside the county "RS_0001" and 3) a another point nearby "RS_0002". Dual Frequency data was logged continuously for the duration of each LiDAR flight mission at a one-second sampling rate. A table of control points for the LiDAR survey is included in Section 5 of this report.
The flight plan for LiDAR consisted of parallel flights in a north-east/south-west extent across the site (see Figure B, LiDAR Flight Layout). Sixty-three (63) flight lines of LiDAR data were acquired in 5 sessions along with 1 cross flight across the County.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.

Accuracy
High density LiDAR data acquisition within the project limits (see Figure A, Project Boundary/LiDAR Coverage) at a sufficient altitude and density to support digital terrain model (DTM) development capable of generating 2-foot contours with a vertical accuracy of 1.2-feet RMSE at the 90% confidence level.
Horizontal Positional Accuracy
The complete LiDAR data set for the entire project area was delivered to URS on July 19, 2006. URS conducted a data assessment and provided comments and examples to Woolpert for delivery on August 4, 2006.URS indicated the LiDAR data met the vertical and horizontal accuracy requirements for each of the land use categories.; Quantitative Value: 3.353 meters, Test that produced the value: 3.353 meters at 90% confidence interval
Vertical Positional Accuracy
Woolpert Inc. conducted a topographic LiDAR survey to support the South Carolina FEMA Map Modernization Program and the generation of 2-foot contours with a vertical accuracy of 1.2-feet at the 90% confidence level. The LiDAR data was acquired across the project limits only.; Quantitative Value: 0.366 meters, Test that produced the value: 36.6 cm at 90% confidence interval

The LiDAR data acquisition was executed in five sessions, on March 15, 16 & 17, 2006, using a Leica ALS50 LiDAR System. Specific details about the ALS50 system are included in Section 4 of this report.
The three airborne GPS (ABGPS) base stations supporting the LiDAR acquisition were located on 1) a NGS SAC monumented control point inside Bush Field Airport (AGS), point AA2799, 2) a point inside the county "RS_0001" and 3) a another point nearby "RS_0002". Dual Frequency data was logged continuously for the duration of each LiDAR flight mission at a one-second sampling rate.
The LiDAR data was acquired using 2 ALS50's onboard 2 Cessna T404's. The ALS50 LiDAR system, developed by Leica Geosystems of Boston, Massachusetts, includes the simultaneous first, intermediate and last pulse data capture module, the extended altitude range module, and the target signal intensity capture module. The system software is operated on a P-400 Diagnostic System Laptop Computer aboard the aircraft.
Woolpert performed ABGPS surveying during the LiDAR mission to derive the flight trajectory at a half-second interval. ABGPS is a critical factor in LiDAR data collection. As such, we spent considerable time developing flight windows around the satellite constellation. We also developed multiple base stations to provide redundancy and to reduce ionospheric and atmospheric errors due to distance separation between the aircraft and the base stations.
At a minimum, two base stations were in operation for every LiDAR acquisition session, operating at a half-second sampling rate. Final adjusted control point values were used to process the LiDAR data. The survey report includes extensive data about the procedures and results for the ground control survey.
As a continuing quality control measure, data was downloaded each evening in the field to verify a strong GPS solution and then refined in-house to determine final trajectories.
A base-station control survey was performed to provide uniformity and to ensure consistency between the ground control and Airborne GPS. All ground control surveys were performed to achieve accuracies consistent with a second-order, class I horizontal (meets or exceeds 1:50,000) and third-order vertical survey as outlined in Geometric Geodetic Accuracy Standards and Specifications for Using GPS Relative Positioning Techniques, Version 5.0, of August 1, 1989, published by the Federal Geodetic Control Committee (FGCC).

URS provided Woolpert 843 polygons indicating areas to be corrected. In response, Woolpert provided an ESRI shapefile that identifies 3 categories: CORRECTED, EDIT-UNNEEDED and SWAMP_TREE_AREA. Of the 843 edit areas provided by URS, Woolpert corrected 683 and left 160 unchanged based on review and/or inclusion of breaklines.
Woolpert resubmitted the LiDAR data to URS on Sept 14, 2006. On October 4, 2006 Woolpert received comments from URS that additional editing was still required. Woolpert agreed to review all the bridge locations within the detailed study area and make the appropriate corrections. Woolpert than resubmitted the LiDAR data on November 4, 2006 and it was accepted on November 29, 2006.

The NOAA Office for Coastal Management (OCM) received the files in laz format from SCDNR via an FTP online repository. The files contained lidar elevation and intensity measurements. The data were in State Plane, NAVD88 (orthometric) heights in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The data were converted from state plane coordinates to geographic coordinates.
2. The data were converted from NAVD88 (orthometric) heights in meters to GRS80 (ellipsoid) heights in meters using Geoid 09.
3. The LAS data were sorted by latitude and the headers were updated.
2015-02-21T00:00:00
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)
