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 by December 31, 2009, 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, <NCMP> is the project under which data were collected, <CA> is the area of data collection, <001> is the "Box" number and <H> 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. 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. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian asNeeded https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/4825/supplemental/ca2010_ncmp_m4825.kmz This graphic shows the lidar coverage for the 2010 USACE Topobathy Lidar:California data set. kmz DOD/USARMY/USACE/SAD/MOBILE > Mobile District, South Atlantic Division, U.S. Army Corps of Engineers, U.S. Army, U.S. Department of Defense dataCentre Global Change Master Directory (GCMD) Data Center Keywords 23.3 EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION theme Global Change Master Directory (GCMD) Science Keywords 23.3 CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > CALIFORNIA VERTICAL LOCATION > LAND SURFACE VERTICAL LOCATION > SEA FLOOR place Global Change Master Directory (GCMD) Location Keywords 23.3 LIDAR > Light Detection and Ranging instrument Global Change Master Directory (GCMD) Instrument Keywords 23.3 OCEANS > BATHYMETRY > SEAFLOOR TOPOGRAPHY > BATHYMETRY theme GCMD Earth Sciences Keywords California San Luis Obispo United States place Geographic Names Information System ALS60 JALBTCX SHOALS U.S. Army Corps of Engineers theme 2010 August June May temporal Lidar - partner (no harvest) project InPort otherRestrictions Cite As: OCM Partners, [Date of Access]: 2010 USACE NCMP Topobathy Lidar: California [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49641.

Bathymetric data - The data provided were tested against ground truth data. At these locations the lidar data matched within 0.30 meters (RMSE 95% confidence level). The USACE collected, processed, and provided the data to the NOAA Office for Coastal Management (OCM). OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https. Topographic data - These data were collected using the ALS60 lidar system. They are owned by Fugro EarthData and operated through contract. The system collects topographic lidar data at maximum pulse rate of 200 kHz in a wavelength of 1064 nm. A CASI-1500 hyperspectral line scanner is integrated with the system. Aircraft position, velocity and acceleration information are collected by the onboard GPS/IMU system. Raw data were transferred to the office and processed in IPAS 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 processing, validation and QA/QC in the software packages GeoCue and TerraScan, anomalous data are flagged as invalid and necessary reflights are called. Fugro's proprietary software converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID09 model and exports topographic data as a series of LAS files with a single file per flightline per 5km box. Topographic data - 1. The raw lidar data was processed through a minimum block mean algorithm, and points were classified as either bare earth or non-bare earth. 2. User developed macros that factor mean terrain angle and height from the ground were used to determine bare earth point classification. 3. The next phase of the surfacing process was a 2D edit procedure that ensures the accuracy of the automated feature classification. 4. Editors used a combination of imagery, intensity of the lidar reflection, profiles and tin-editing software to assess points. 5. The lidar data was filtered, as necessary, using a quadric error metric to remove redundant points. This method leaves points where there is a change in the slope of surfaces (road ditches) and eliminates points from evenly sloped terrain (flat field) where the points do not affect the surface. 6. The algorithms for filtering data were utilized within Fugro EarthData's proprietary software and commercial software written by TerraSolid. 7. The flight line overlap points were merged back into filtered data set for delivery product. 8. The point cloud data were delivered tiled in LAS 1.0 format; unclassified (1), ground (2), low/noise (7), water (9), and overlap (12). 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. 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). Office for Coastal Management processor The topographic and bathymetric data were received by the Office for Coastal Management (OCM). The topographic data were in las format and the bathymetric data were in ASCII format. The topographic and bathymetric data were in orthometric (NAVD88) heights and in geographic coordinates. The following steps document the processing of the data for Digital Coast storage and provisioning purposes: 1. The topographic data were converted from orthometric heights to ellipsoid heights using GEOID09. 2. The bathymetric data were converted from orthometric heights to ellipsoid heights using GEOID09. 3. All points were converted to laz format. 2015-03-24T00:00:00 USACE JALBTCX USACE JALBTCX originator
