Full Citation Examples
Digital Elevation Model (DEM) derived from lidar data.
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

---|---|
Vertical Positional Accuracy: |
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. 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. CHARLESTON COUNTY: Based on a control-to-LiDAR comparison, LiDAR data delivered for this project returned an RMSE of 0.092 m and an Accuracy of 0.18 m at the 95% confidence level in open terrain, based on 26 points. Combined Vertical Accuracy (CVA) is 0.183 m at the 95% confidence level, based on 75 points. |
Completeness Report: |
All project tasks have been completed. No known data gaps exist (with the exception of water areas) within the project area. |

Process Steps
Process Step 1
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 Step 2
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 Step 3
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. |
