Abstract:

These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Riegl VQ820G system. The data were acquired from 20160721 - 20161121. The data includes topobathy data in an LAS 1.2 format file classified as unclassified (1), noise (7), bathymetric point (26), and submerged object (29) in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set may also include lidar intensity values and encoded RGB image values.

Purpose:

This lidar data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar.

Notes:

10199

Supplemental Information:

Data include all lidar returns. Outliers or false returns (e.g., returns from birds, atmospheric particles, and/or system noise) may be present in the data. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not all returns were correctly classified; therefore the user should examine for acceptability.

Data Quality

Horizontal Positional Accuracy:

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than plus or minus 1.0 m.; Quantitative Value: 1.0 meters, Test that produced the value: 1 Sigma

Vertical Positional Accuracy:

The data positions were obtained using post processed KGPS methods. Data used to test the lidar was collected with Static GPS Observations and compared against the published data. The vertical accuracy of the data is better than plus or minus 0.15 m.; Quantitative Value: 0.15 meters, Test that produced the value: 1 Sigma

Completeness Report:

Data covers the 2452 tiles (500m x 500m tiles).

Process Steps

Process Step 1

CC ID: 1061125
Description:

Data were processed to an initial LAS format using the Riegl RiProcess software. The Applanix POSPac software was utilized for GPS and inertial processing, and GeoCue, Terrasolid, and LP360 software for data visualization, 3D editing, and export to final LAS file. Data were processed in NAD83 horizontal and vertical datum.

Process Date/Time: 2017-03-27 00:00:00

Process Step 2

CC ID: 1061126
Description:

The NOAA Office for Coastal Management (OCM) received files in las format. The files contained lidar elevation and intensity measurements of the Florida Keys Outer Reef Block 01. The data were in UTM Zone 17 coordinates and ellipsoid elevations in meters. The data classifications for the data are: 1 - unclassified, 7 - noise, 26 - bathymetric point, and 29 - submerged object . OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Converted from UTM Zone 17 to geographic coordinates 2. Sorted by gps time 3. Compressed the data using laszip
