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

CC ID: 1135317
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 Date/Time: 2006-02-10 00:00:00

Process Step 2

CC ID: 1135318
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

CC ID: 1135319
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

CC ID: 1135320
Description:

For data managment purposes, the Office for Coastal Management converted the data from NAVD88 elevations to ellipsoid

elevations using Geoid 03.
