Data Quality

Horizontal Positional Accuracy:

Unknown; Quantitative Value: 1.0 meters, Test that produced the value: Horizontal accuracy is not explicitly stated, default value of 1 m

Vertical Positional Accuracy:

Unknown; Quantitative Value: 0.09 meters, Test that produced the value: The standard deviation of the differences between the ALTM nearest neighbor shot and the ground truth points was about 9 cm on all flights. After analysis, all trajectories showed height shifts of between 10 and 15 cm.

Completeness Report:

complete

Conceptual Consistency:

In order to provide on-site calibration and ground truth, a section of the Plum Island Turnpike running east and west just north of the project polygon was surveyed using vehicle-mounted GPS, and then surveyed with the ALTM during the flight. Comparisons were made between the heights of the vehicle-collected GPS and the airborne laser scanner. This allowed for a check on the calibration of the airborne scanner as well as a measure of the accuracy of the scanner heights.

Process Steps

Process Step 1

CC ID: 1134516
Description:

During processing, a scan cutoff angle of 4.0 degrees was used to eliminate points at the edge of the scan lines. This was done to improve the overall DEM accuracy (points farthest from the scan nadir are the most affected by small errors in pitch, roll and scanner mirror angle measurements). Points with very low intensity values were also filtered out (intensity values less than 7), because these points also tend to be the least accurate. This is due to the fact that very weak return pulses yield the noisiest range measurements. These points represent a very small percentage of the total number of points, usually in the neighborhood of a few hundredths of one percent. All calibration files as well as all raw observation files (both GPS and ALTM) necessary to reprocess this project in its entirety are archived by UC Berkeley.

Process Step 2

CC ID: 1134517
Description:

The NOAA Office for Coastal Management (OCM) received the files in laz format via download from the OpenTopography online repository. The files contained lidar elevation and intensity measurements. The data were in Mainland Massachusetts State Plane Zone 2001 (orthometric) heights in meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes:

1. The data were converted from state plane orthometric coordinates to geographic coordinates.

2. The data were converted from NAVD88 heights in meters to GRS80 (ellipsoid) heights in meters using Geoid 03.

3. The LAS data were sorted by latitude and the headers were updated then stored as LAZ data.
