Data Quality

Horizontal Positional Accuracy:

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is

better than +/- 3.0m.

; Quantitative Value: 3.0 meters, Test that produced the value: 2 Sigma

Vertical Positional Accuracy:

The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is

better than +/- 0.30m.

; Quantitative Value: 0.30 meters, Test that produced the value: 2 Sigma

Completeness Measure:

Cloud Cover: Unknown

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:

Lidar data between different flight lines matched within 0.20 meters

Process Steps

Process Step 1

CC ID: 1135365
Description:

These data were collected using a SHOALS-1000T system.

It is owned and operated by Fugro Pelagos performing

contract survey services for the US Army Corps of

Engineers.

The system collects topographic lidar data at 10kHz and

hydrographic data at 1kHz. The system also collects RGB

imagery at 1Hz.

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 greographic tiles

covering approximately 5km each.

Process Date/Time: 2006-04-24 00:00:00

Process Step 2

CC ID: 1135366
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: 2006-07-15 00:00:00

Process Step 3

CC ID: 1135367
Description:

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

elevations using Geoid 03.
