High density LiDAR data acquisition within the project limits at a sufficient altitude and density to support digital terrain model (DTM) with a Vertical Accuracy of 2.4 feet RMSE at a 90% confidence level and a Horizontal Accuracy of 11 feet RMSE at a 90% confidence level.

Horizontal Positional Accuracy:

Horizontal Accuracy 3.353 feet RMSE 90% confidence level; Quantitative Value: 3.353 meters, Test that produced the value: 3.353 meters RMSE at 90% confidence level

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 2.4-feet at the 90% confidence level. The LiDAR data was acquired across the project limits only.; Quantitative Value: 0.732 meters, Test that produced the value: 73.2 cm at 90% confidence interval

Lineage

Process Steps

Process Step 1

CC ID: 1136702
Description:

The LiDAR data acquisition was executed in 5 sessions, from March 7 to March 9, 2007.

The airborne GPS (ABGPS) base stations supporting the LiDAR acquisition consisted of the bases set up by the flight crews at the Anderson Airport (KAND). Dual Frequency data was logged continuously for the duration of each LiDAR flight mission at a one-second sampling rate or better. The flight plan for LiDAR consisted of parallel flights in a north-south extent across the site. Fifty-four (54) flight lines of LiDAR data were acquired.

In this process, Woolpert employed GPS differential processing and Kalman filtering techniques to derive an aircraft trajectory solution at 1-second intervals for each base station within the project limits. Statistics for each solution (base station) were generated and studied for quality. The goal for each solution is to have:

maintained satellite lock throughout the session

position standard deviation of less than 5 centimeters

low ionospheric noise

few or no cycle slips

a fixed integer ambiguity solution throughout the trajectory

a maximum number of satellites for a given constellation

a low (3.0 or less) Position Dilution of Precision (PDOP)

Often times a solution for a given base station will meet all of the above parameters in certain portions of the trajectory while the other base station might meet the above conditions in different portions of the trajectory solution. In this case, further processing was done to form different combinations of base station solutions and/or satellites to arrive at the optimal trajectory.

Process Step 2

CC ID: 1136703
Description:

LiDAR QA/QC verification will be provided by SCDNR through their contractor URS Corporation.

The complete LiDAR data set for the entire project area was delivered to URS on August 15, 2007. URS conducted a data assessment. URS provided the review comments on October 10, 2007. URS indicated the LiDAR data met the vertical and horizontal accuracy requirements for the project and would not require any additional work.

Process Date/Time: 2007-10-10 00:00:00

Process Step 3

CC ID: 1136704
Description:

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 03.

3. The LAS data were sorted by latitude and the headers were updated.
