information
These files contain bathymetric lidar data collected by the SHOALS-1000T system along the coast of California. Data coverage generally extends along the
coastline from the waterline offshore 1,000 meters or to laser extinction. Exclusively in areas where Fugro Pelagos acquired or planned to acquire
multibeam sonar data by December 31, 2009, data coverage extends from the shoreline either to the 10-m contour, the 20-m contour or the landward extent
of the multibeam data plus an additional 100 m offshore. The SHOALS system has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). Native lidar
data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages are
used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis. Horizontal
positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are
referenced to the NAD83 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID09 model is used to transform the vertical positions
from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). Both ellipsoidal and orthometric heights were
provided to NOAA OCM. For data storage and Digital Coast provisioning, NOAA OCM processed the ellipsoidal height data.

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above and below the water line in the
California coastal zone.

High water turbidity in the survey area hindered the acquisition of bathymetric data in boxes 23,24,25,31,33,34,35 and 36 and resulted in incomplete coverage.

Conceptual Consistency
The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.30 meters (RMSE 95% confidence level)
These data were collected using the SHOALS-1000T system. It is owned by Fugro Pelagos Inc. and operated through contract. The system collects bathymetric
lidar data at 1kHz and RGB imagery at 1Hz. A CASI-2 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and
acceleration information are collected through a combination of Novatel and POS A/V 410 equipment. All raw data streams are transferred to the office for
downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar
data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software package Fledermaus, anomalous data are flagged as invalid.
FPI Workbench then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID09 model and exports data as a series of
bathymetry (H) ASCII files. The bathymetry files contain all of the returns from the bathymetric sensor which include returns both above and below the water.

The NOAA Office for Coastal Management (OCM) received ASCII formatted data in geographic coordinates and ellipsoid heights in meters. The files
contained lidar intensity and elevation measurements. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. The data were converted from ASCII format to LAS format.
2. The data were classified as 11 (Bathymetry).
3. The processed las files were zipped.
2012-05-01T00:00:00
Times had originally been stored as POSIX seconds when converted to LAS. This was switched to adjusted GPS time (GPS seconds - 1e9) to conform to the LAS 1.2 standard.
2014-01-09T00:00:00
The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
