Data was collected by Fugro for the University of South Florida. The RAMMS system integrates a bathymetric lidar sensor and a digital camera on a single remote sensing platform for use in coastal mapping and charting activities. Lidar data has been processed onto LAS v1.4 format, cleaned and classified. Spatial reference datums is NAD83 (2010). Depths and elevations are Elipsoidal. Additional classification of terrestrial points was by NOAA using automated software. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section.

Every effort was made to recover as much valid point depths; gaps in the coverage are mostly caused by negative bottom detection or by the removal of data below the accuracy tolerance. Unfavorable weather conditions for survey and safe airborne navigation prevented the completion of all planned survey lines (ice on the water, snow on the ground).

Some lines were re-flown. Conceptual Consistency The data provided in these files were constricted to IHO SP-54 Order 1a accuracy standards The data was collected using the RAMMS LiDAR system. It is owned by Fugro and operated through contract. The system collects bathymetric lidar data at 30 Hz lidar pulse and generates up to 900 beams per pulse. RGB imagery was collected with a PhaseOne iXM-50 digital camera. Aircraft position, velocity and acceleration information were collected through POS AV 510 v6 equipment. All raw data streams were transferred to the field office for downloading and processing in RAMMS Processing Module software. Aircraft position data were processed using POSPac software and the results were combined with the lidar data to produce 3D positions for each beam points. Upon QA/QC in the Terrasolid software suite, point cloud data was classified into bathytmetry, topography and other non-terrain classes. All valid topography are class 2; depths are class 40 and 43. The data were received in LAS 1.4 format from the University of South Florida. The data generally appeared to follow the topobathy domain profile, but also contained undefined lidar classifications. The Class histogram for the dataset was: Class Number and Point count: 0 378141361 1 19235839 2 117 7 4786920 8 1 9 6407 12 168653570 18 511160148 22 1204 30 218426 40 407816951 41 844187621 42 1607 45 168647432 This does not agree with the previous step's statement that all valid topography are class two. Examination of the data also revealed that class 7 and class 18 (low noise and high noise) are essentially flipped in the water areas, with low noise near the water surface and high noise below the sea floor. Class 12 appeared to be a subset of the points over terrestrial areas, but was clearly not a ground class. All points in classes 0, 1, 8, 12, 22, and 30 were recombined into class 1 and extracted into separate files. Automated processes to identify noise and ground points (lasnoise and lasground_new from LAStools) for the separated files. The files separated by class were re-merged after classification. Points marked as withheld were dropped from the dataset. These were typically on noise points. Other classification flags may have limited validity. For example, the flag keypoints was found on many unclassified points. For ingest into the Digital Coast Data Access Viewer, the points were converted to geographic coordinates and cloud optimized point cloud (COPC) format. The final classification histogram is: class count 1 434155871 2 131616712 7 4669842 9 6407 18 511145834 40 407816951 41 844187621 42 1607 45 168647432 2023-07-14T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Point Cloud produced by Fugro University of South Florida originator The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2026-08-12NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
