LiDAR data collection was performed utilizing a Leica ALS-50 sensor, collecting multiple
return x, y, and z data as well as intensity data. LiDAR data was processed to
achieve a bare ground surface, and was delivered in LAS format. Classified LAS data was
also used as a base for collection of hydro features, delivered in MicroStation v8
format. This data was collected in:
1. Jasper County, SC from 20061227 to 20070216
2. Colleton County, SC from 20070216 to 20070323
Lidar data was acquired for Jasper and Colleton Counties, SC as part of a collaborative effort
by state agencies, FEMA and the NOAA Coastal Services Center to provide high-resolution topographic
data for floodplain mapping and other uses.

Elevation and hydrography data was delivered covering the full extent of Jasper and Colleton Counties,
South Carolina.
All project tasks have been completed. No known data gaps exist (with the exception of
water areas)within the project area.
For Jasper County: Horizontal accuracy is 1 m based on collection specifications.
For Colleton County: Horizontal accuracy is 1 m based on collection specifications.
For Jasper County: Based on a control-to-LiDAR comparison, LiDAR data delivered for this project
returned an RMSE of 0.06 m and an Accuracy of 0.12 m in open terrain, based on 42 points.
Combined Vertical Accuracy (CVA) is 0.30 m based on 108 points.
For Colleton County: Based on a control-to-LiDAR comparison, LiDAR data delivered for this project
returned an RMSE of 0.068 m and an Accuracy of 0.13 m in open terrain, based on 21 points.
Combined Vertical Accuracy (CVA) is 0.22 m based on 91 points.

Raw LiDAR elevation data utilized in production of final bare ground surface.
For Jasper County: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover
Jasper County, South Carolina. Data was collected in a total of 111 flightlines at a pulse rate of
75,000 points per second.
For Colleton County: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover
Colleton County, South Carolina. Data was collected in a total of 160 flightlines at a pulse rate of

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
softwares). 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 softwares.

Following bare ground surface creation (Process Step 2),Photo Science utilized the resulting dataset
as a source for collection of hydrographic features, including double-line drains, single-line drains,
and bodies of water. Hydro features were collected from bare ground surface models in MicroStation v8
software. After collection was complete, Photo Science adjusted elevation of all hydro features to
ensure proper monotonicity using FME and proprietary softwares.

The NOAA Coastal Services Center (CSC) received files in LAS format.
The files contained LiDAR intensity and elevation measurements. CSC performed the following
processing on the data to make it available within the LiDAR Data Retrieval Tool (LDART)
1. The data were converted from UTM (Zone 17) coordinates to geographic coordinates.
2. The LAS data were sorted by latitude and the headers were updated.
