Abstract:

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. The dates of collection are:

1. JASPER COUNTY (full county): 20061227 to 20070216

2. COLLETON COUNTY (full county: 20070216 to 20070323

3. CHARLESTON COUNTY (Partial County): 20070222 to 20070223

Process Steps

Process Step 1

CC ID: 625147
Description:

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.

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 75,000 points per second.

CHARLESTON COUNTY: Utilizing Photo Science's two ALS-50 LiDAR sensors, data was collected to cover Charleston County, South

Carolina. Data was collected in a total of 77 flightlines at a pulse rate of 75,000 points per second.

Process Date/Time: 2007-03-23 00:00:00

Process Step 2

CC ID: 625148
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.

Process Date/Time: 2007-10-30 00:00:00

Process Step 3

CC ID: 625149
Description:

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 software.

Process Date/Time: 2007-10-30 00:00:00

Process Step 4

CC ID: 625150
Description:

The NOAA Office for Coastal Management (OCM) received files in LAS format. The files contained LiDAR intensity

and elevation measurements. OCM 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.
