Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 11 (valid bathymetric data). Classes 1 and 2 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. These data were collected by the Coastal Zone Mapping and Imaging Lidar (CZMIL) system. CZMIL integrates a lidar sensor with simultaneous topographic and bathymetric capabilities, a digital camera and a hyperspectral imager on a single remote sensing platform for use in coastal mapping and charting activities. Native lidar data is not generally in a format accessible to most Geographic 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 LAS files, which are tiled into quarter-quads or 5km boxes. The LAS file index is provided by the shape file, "MS_Boxes_NCMP_and_QuarterQuads.shp", 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, effort, area name, "Box" number and product type. An example file name is "2012_NCMP_MS_29_GeoClassified.las", where 2012 is the year of data collection, NCMP is the project under which data were collected, MS is the area of data collection, 29 is the "Box" number and GeoClassified is the product type. This data was provided to the NOAA Office for Coastal Management (OCM) for data distribution from the Data Access Viewer (DAV) and https. 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 NCMP to depict the elevations above and below the water in the Mississippi 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/geoid18/4749/supplemental/ms2012_ncmp_gulfport_m4749.kmz This graphic shows the coverage of the 2012 Gulfport, MS topobathy lidar collection. kmz DOD/USARMY/USACE/SAM/MOBILE/OPJ/JALBTCX > Joint Airborne Lidar Bathymetry Technical Center of Expertise, 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 > HUMAN DIMENSIONS > ENVIRONMENTAL GOVERNANCE/MANAGEMENT > LAND MANAGEMENT > LAND USE CLASSES EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL LANDFORMS EARTH SCIENCE > LAND SURFACE > GEOMORPHIC LANDFORMS/PROCESSES > COASTAL PROCESSES EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > BATHYMETRY EARTH SCIENCE > OCEANS > BATHYMETRY/SEAFLOOR TOPOGRAPHY > SEAFLOOR TOPOGRAPHY EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION theme Global Change Master Directory (GCMD) Science Keywords 23.3 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 Joint Airborne Lidar Bathymetry Technical Center of Expertise Mobile District Spatial Data Branch United States Army United States Army Corps of Engineers theme GCMD Data Center Keywords v7 Gulfport Mississippi United States place Geographic Names Information System IWG-OCM National Coastal Mapping Program (NCMP) U.S. Army Corps of Engineers (USACE) theme Lidar - partner (no harvest) project InPort otherRestrictions Cite As: OCM Partners, [Date of Access]: 2012 USACE NCMP Topobathy Lidar: Gulfport, MS [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49822.

JALBTCX evaluates the horizontal accuracy of the final data coverage against available basemap imagery products. The final lidar point cloud is gridded according to procedures defined in the JALBTCX Standard Operating Guide and Appendices (SOGA). The grid products are then visually compared to basemap imagery products to verify the horizontal positions of large buildings and other urban features with the data coverage. Vertical Positional Accuracy CZMIL topographic data - Compiled to meet 20 cm vertical accuracy at 95% confidence level. CZMIL bathymetric shallow FOV data - Compiled to meet SQRT((0.20^2) +((0.0075d)^2)) m vertical accuracy at 95% confidence level, d is depth. CZMIL bathymetric deep FOV data - Compiled to meet SQRT((0.30^2) +((0.013d)^2)) m vertical accuracy at 95% confidence level, d is depth. JALBTCX evaluates the vertical accuracy of the final data coverage against traditional ground-truth data. Ground-truth data is acquired and utilized according to specifications outlined in the JALBTCX Standard Operating Guide and Appendices (SOGA) as well as the USGS Lidar Base Specification. The final lidar point cloud at every project ground-truth location is compared against ground-truth points in the 'bare_ground' class. Comparisons are performed in the QCoherent LP360 software package, and the final results are output to JALBTCX's Ground Truth Comparison Report. Completeness Report This data set covers the spatial extent of topographic lidar data obtained during this survey. Conceptual Consistency During inspection and QC of the lidar point cloud, flightline to flightline elevation differences met the CZMIL sensor specifications. 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. These data were collected using the CZMIL system. It is owned and operated by the U.S. Army Corps of Engineers (USACE). The system collects topobathy lidar data at 10 kHz and RGB imagery at 2 Hz. A CASI-1500 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 510 equipment. All raw data streams are transferred to the office for downloading and processing in CZMIL's Hydro Fusion 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 packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE software then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID12A model and exports valid lidar data as a series of unclassified LAS files. 2013-06-08T00:00:00 LAS files are imported into GeoCue V2012.1.27.7, which is a geospatial workflow production and management software tool employed by JALBTCX to perform and monitor production of data products. Upon import into GeoCue, a customized classification macro, built upon the TerraScan V13 module within Microstation V8i, classifies valid topobathy data as ground points (2) and unclassified points (1), and valid bathymetric points (29). Upon completion the macro, the classification results undergo quality control and any misclassified points are manually edited. In areas of dense vegetation the bare earth ground points might be incorrectly classified due to the inability of the laser to penetrate the canopy and reach the bare ground. In these areas, JALBTCX defaults to the algorithm's "ground" surface instead of manually reclassifying those points. They are partitioned into a series of 5km or quarter quad delivery boxes, one Classified LAS file per box. The format of the file is LAS version 1.2. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (valid bathymetric data). Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 National Adjustment of 2011 (NAD83 NA2011). Vertical positions are referenced to the NAD83 NA11 ellipsoid and provided in meters. The National Geodetic Survey's (NGS) GEOID12A model is used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). 2013-11-29T00:00:00 The NOAA Office for Coastal Management (OCM) received the topographic lidar files in LAS format. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The files were reviewed and erroneous elevations were removed. 2. Class 29 were reclassified to Class 11 (bathymetry). 2015-01-07T00:00:00 In April 2020, the NOAA Office for Coastal Managment (OCM) received 4 las files from USACE JALBTCX that replaced the existing files already in use in the Data Access Viewer (DAV). The lidar data had elevation and intensity measurements. The data were in geographic coordinates (NAD83 2011) and ellipsoid elevations in meters. The data were classified as: 1 - Unclassified, 2 - Ground, 29 - Bathymetric Point. OCM processed all classifications of points to the Digital Coast Data Access Viewer (DAV). Classes available on the DAV are: 1, 2, 29. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges. 2. Internal OCM scripts were run on the laz files to assign the geokeys, to sort the data by gps time and zip the data to database and to https. 2020-04-29T00:00:00 Office for Coastal Management processor USACE JALBTCX USACE JALBTCX originator
