Abstract:

This dataset is part of a regularly scheduled update of planimetric, hydrographic, and topographic features.

Data Quality

Accuracy:

Verification of attribute accuracy for Lidar data involves the use of filtering techniques. Auto-filtering uses algorithms to reclassify data in the point cloud. Hand-filtering involves the analysis of a technician working in a graphic environment to reclassify the erroneous points that may remain in the Lidar point cloud after auto-filter.

Horizontal Positional Accuracy:

N/A

Vertical Positional Accuracy:

NSSDA accuracy of 0.5292 feet exceeds Fundamental Vertical Accuracy (FVA) requirement of 0.6 feet; Quantitative Value: 0.082296 meters, Test that produced the value: RMSE(z)

Completeness Measure:

Cloud Cover: 0

Completeness Report:

The dataset was reviewed to ensure completeness and accuracy.

Conceptual Consistency:

Calibrations of the Lidar flight line data are performed; this process is known as bore sighting. The flight lines are compared to evaluate both their relative and absolute accuracies.

Process Steps

Process Step 1

CC ID: 1139243
Description:

Lidar data was collected using Leica's ALS50 Phase I sensor. The raw data was verified in MARS software for complete coverage of the project area, and bore sighted to align the flight lines. Raw data files were parsed into manageable client-specific tiles. These tiles were then processed through automated filtering that separates the data into different classification groups: unclassified points, ground points, "noise" points and water. The data was next taken into MARS to reclassify the erroneous points that may remain in the Lidar point cloud after auto-filter.

Process Date/Time: 2009-01-01 00:00:00

Process Step 2

CC ID: 1139244
Description:

The NOAA Office for Coastal Management (OCM) received the lidar files in las format. The files contained lidar intensity

and elevation measurements. OCM performed the following processing for data storage and Digital Coast provisioning purposes:

1. Data converted from State Plane coordinates to geographic coordinates.

2. Data converted from NAVD88 heights to ellipsoid heights using GEOID03.

3. The LAS data were sorted by latitude and the headers were updated.
