Data Quality
| Accuracy: |
Data are not attributed. | Quantitative Value: N/A | Quantitative Test Explanation: These data are not attributed. |
|---|---|
| Horizontal Positional Accuracy: |
The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75m. ; Quantitative Value: 0.75 meters, Test that produced the value: 1 Sigma |
| Vertical Positional Accuracy: |
The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20m. ; Quantitative Value: 0.20 meters, Test that produced the value: 1 Sigma |
| Completeness Report: |
These data covered the required survey area with minimal gaps in data coverage. The data postings are very consistent with postings at about 1.3m density. |
| Conceptual Consistency: |
The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters, and different flight line data agreed within 0.20 meters. |

Process Steps
Process Step 1
| Description: |
These data were collected using the CHARTS surveys system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 20kHz and hydrographic data at 3kHz. The system also collects RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V equipment. Raw data are collected and transferred to the office for downloading and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the dataset. The edited data are unloaded from SHOALS GCS, converted from ellipsoid to orthometric heights, based on the GEOID03 model, and split into geographic tiles covering approximately 5km each. |

Process Step 2
| Description: |
The NOAA Office for Coastal Management (OCM) received files in ascii 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. Each hydro/topo last return ascii file was converted to las files. Default values for which there is no corresponding input were assigned as follows for each las elevation data record: intensity = 0, retn = 1, nret = 1, class = 0 2. The las files were sorted by latitude and the las header fields were updated. |
|---|---|
| Process Date/Time: | 2006-04-21 00:00:00 |
Process Step 3
| Description: |
Times had originally been stored as POSIX seconds when converted to LAS. This was switched to adjusted GPS time (GPS seconds - 1e9) to conform to the LAS 1.2 standard. |

| Process Date/Time: | 2014-01-09 00:00:00 |
Process Step 4
| Description: |
For data managment purposes, the Office for Coastal Management converted the data from NAVD88 elevations to ellipsoid elevations using Geoid 03. |
