The data, hosted by the NOAA Office for Coastal Management, can be customized and requested for free download through a checkout interface. An email provides a link to the customized data, while the original data set is available through a link within the viewer. function: (CI_OnLineFunctionCode) download role: (inapplicable) abstract: 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, <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. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: 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. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded graphicOverview: (MD_BrowseGraphic) fileName: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/4826/supplemental/ca2011_ncmp_m4826.kmz fileDescription: This graphic shows the lidar coverage for the 2011 USACE Topobathy Lidar:California data set. fileType: kmz descriptiveKeywords: (MD_Keywords) keyword: DOD/USARMY/USACE/SAD/MOBILE > Mobile District, South Atlantic Division, U.S. Army Corps of Engineers, U.S. Army, U.S. Department of Defense type: (MD_KeywordTypeCode) dataCentre thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Data Center Keywords date: (missing) edition: 10.7 descriptiveKeywords: (MD_Keywords) keyword: EARTH SCIENCE > LAND SURFACE > LAND USE/LAND COVER keyword: EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION keyword: EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (missing) edition: 12.3 descriptiveKeywords: (MD_Keywords) keyword: VERTICAL LOCATION > LAND SURFACE keyword: VERTICAL LOCATION > SEA FLOOR type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Location Keywords date: (missing) edition: 12.3 descriptiveKeywords: (MD_Keywords) keyword: LIDAR > Light Detection and Ranging type: (MD_KeywordTypeCode) instrument thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Instrument Keywords date: (missing) edition: 14.9 descriptiveKeywords: (MD_Keywords) keyword: OCEANS > BATHYMETRY > SEAFLOOR TOPOGRAPHY > BATHYMETRY type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: GCMD Earth Sciences Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: California keyword: San Mateo keyword: United States type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Geographic Names Information System date: (missing) descriptiveKeywords: (MD_Keywords) keyword: ALS60 keyword: JALBTCX keyword: SHOALS keyword: U.S. Army Corps of Engineers type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: 2010 keyword: 2011 keyword: June keyword: May type: (MD_KeywordTypeCode) temporal descriptiveKeywords: (MD_Keywords) keyword: Lidar - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: Cite As: OCM Partners, [Date of Access]: 2011 USACE NCMP Topobathy Lidar: California [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49644. resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

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. processStep: (LI_ProcessStep) description: 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. processStep: (LI_ProcessStep) description: 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). 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). processStep: (LI_ProcessStep) description: Bathymetric data - 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). processStep: (LI_ProcessStep) description: 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. dateTime: DateTime: 2015-03-20T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: USACE JALBTCX date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: USACE JALBTCX role: (CI_RoleCode) originator processStep: (LI_ProcessStep) description: 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.
