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 on areas where Fugro Pelagos acquired or planned to acquire multibeam sonar data, coverage extends from the shoreline either to the 10-m contour, the 20-m contour or the landward extend 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. The 3-D position data are sub-divided into a series of ASCII file products, with each covering approximately 5 kilometers of shoreline. The file index is provided by the shape file, "CA_Boxes", and the numbers used to identify files are in the "Box" field of the shape file. The data file naming convention is based on the year, project, area name, "Box" number and product type (H - bathymetry). An example file name is "2009_NCMP_CA_001_H.xyz", where <2009> is the project year, is the project under which data were collected, is the area of data collection, <001> is the "Box" number and is the product type. The ASCII columns are Longitude, Latitude, UTM Zone, Easting, Northing, Elevation (orthometric), Elevation (ellipsoid), Date, and Time. In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
