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) presentationForm: (unknown) abstract: These files contain rasterized topobathy lidar elevations generated from data 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. 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). The 3-D position data are used to generate a series of gridded file products, which are tiled into quarter-quads or 5km boxes. The grid file index is provided by the shape file, NC_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 "2014_NCMP_NC_01_BareEarth_1mGrid.tif", where 2014 is the year of data collection, NCMP is the project under which data were collected, NC_Duck is the area of data collection, 01 is the "Box" number, and BareEarth 1mGrid 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). The 1m bare earth raster data are available for custom and bulk download. In addition to this topobathy bare earth Digital Elevation Model (DEM) data, the lidar points data from which these DEMs were created are also available from the NOAA Data Access Viewer. The link to this data is provided in the URL section of this metadata record. purpose: These data were collected as a part of the NCMP to depict the elevations above and below the water in the North Carolina coastal zone. credit: U.S. Army Corps of Engineers (USACE), JALBTCX (Joint Airborne Lidar Bathymetry Technical Center of eXpertise) status: (MD_ProgressCode) completed pointOfContact:

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: 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 topo/bathy 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. dateTime: DateTime: 2013-06-08T00:00:00 processStep: (LI_ProcessStep) description: Data classified as ground points (2) and bathymetric points (29) in the las files are converted to a grid by generating a triangulated irregular network (TIN) and then extracting the grid node elevations from the TIN surface. The origin point of the grid is located at a horizontal position whose value is evenly divisible by the 1m grid resolution such that rasters from subsequent surveys have common cell boundaries. JALBTCX uses Quick Terrain Modeler V8 to perform this operation utilizing the following parameters; “Legacy Triangulation”, "Max Sample Excursion - 30000”, “Max Triangle Side – 30000”, “Radius - none”, “Tolerance – 1”, and “Tiling Settings Snap to Grid (Expand)." The grid is exported from Quick Terrain Modeler as an ESRI ASCII Z grid file. Utilizing an in-house python script within ESRI ArcMap V10.1, the ASCII Z grid file is converted to a tiff-format raster file whose projection is defined as “The North American Datum of 1983 (2011).” The raster is then multiplied against a corresponding 1m Grid mask raster, a mask image produced from JALBTCX’s 1m Grid, in ESRI’s Raster Calculator to remove interpolated areas where data does not exist. dateTime: DateTime: 2013-10-29T00:00:00 processStep: (LI_ProcessStep) description: LAS files are imported into GeoCue V2014.1.21.1, 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), unclassified points (1), and 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). dateTime: DateTime: 2013-10-29T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received 11 GeoTiff format files from USACE JALBTCX for the Duck, NC project area. The bare earth raster files were at a 1 m grid spacing. The data were in geographic NAD83 (2011) coordinates and NAVD88 (Geoid12A) elevations in meters. OCM assigned the appropriate EPSG codes (Horiz - 6318, Vert - 5703) and copied the raster files to https for Digital Coast storage and provisioning purposes. dateTime: DateTime: 2021-04-23T00:00:00 processor: (CI_ResponsibleParty) organisationName: Office for Coastal Management role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: USACE JALBTCX date: (missing) | |
