Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), and 29 (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. In addition to the lidar point data, topobathy bare earth Digital Elevation Models (DEMs) at a 1 meter grid spacing, created from the lidar point data are also available from the NOAA Digital Coast. Links to these data are provided in the URL section of this metadata record. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. This data was collected by USACE on behalf of the NAN (New York District) to assess elevations above and below water along the coast of New Jersey and New York.

Per flight block, elevations in areas of swath overlap are internally consistent and meet CZMIL specifications. Annomalous high and/or low elevation values have been removed, and point cloud classificaiton algorithms have been validated via manual review and QC. Temporal differences in elevation exist in areas of active nearshore processes from the dune to the depth of closure. JALBTCX conducts operations in a manner to ameliorate temporal differences, to include the collection of entire flight blocks within single missions. For a given flight block, it's adjacent flight blocks are captured within 3 days as weather and airspace permit. Horizontal Positional Accuracy CZMIL topographic data - Compiled to meet 1 m horizontal accuracy at 95% confidence level. CZMIL bathymetric data - Compiled to meet 3.5 + 0.05d m horizontal accuracy at 95% confidence level, d is depth. 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((0.25^2) +((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 BaseSpecification. 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 Measure Planned data coverage for this dataset includes the shoreline from Manasquan Inlet, NJ to Sandy Hook, NJ, Staten Island, NY between Great Kills Park and Fort Wadsworth, and the south shore of Long Island, NY from Breezy Point to Montauk Point. Lidar data collection focuses on a narrow swath that captures the beach and dune system to the first line of infrastructure, with the exception of the barrier island between Fire Island Inlet and Shinnecock Inlet, NY, for which the full cross-shore extent of the barrier island was collected. The planned point spacing is 70 centimeters on land and in shallow water. In deeper water the planned point spacing increases to 2 meters. Since the purpose of these surveys is to capture the beach and dune system, bathymetric data was only incidentally collected during acquisition of topographic lidar data. Gaps or data holidays may exist in the bathymetric lidar data coverage. They arise due to a number of operational and environmental conditions, including but not limited to, airspace restrictions, high terrain, active surf, low-reflectivity bottom substrate materials and turbidity in the water column. Please see the Report of Survey for additional details. Completeness Report This data set covers the spatial extent of topographic lidar data obtained during this survey. Conceptual Consistency No discernable offsets or horizontal shifts were found during visual inspecton of the lidar-derived grid products against basemap imagery products. CZMIL data is processed from raw lidar waveforms to point clouds using the CZMIL HydroFusion software package. Point clouds are then classified and edited in industry-standard software packages. Derivative data products are generated through the application of gridding and contouring algorithms in a GIS environment. The data processing workflow, including software packages, algorithms and parameters are provided in detail, herein this metadata as Process Steps. 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 610 equipment. All raw data streams are transferred to the office for downloading and processing in CZMIL’s HydroFusion 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 PFM_ABE, anomalous data are flagged as invalid and have the withheld bit set. 2020-01-20T00:00:00 LAS files are imported into TerraScan V18 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 1-km by 1-km 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). The National Geodetic Survey's (NGS) VDatum software is used to transform the horizontal positions from UTM to Geographic coordinates referenced to the North American Datum of 1983 National Adjustment of 2011 (NAD83 NA11). 2020-01-24T00:00:00 The NOAA Office for Coastal Management (OCM) received 524 ( NJ - 82, NY - 442) las files from USACE JALBTCX. 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. 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 las files to assign the geokeys, to sort the data by gps time and zip the data to database and to https. 2020-02-18T00:00:00 Office for Coastal Management processor Data Source USACE JALBTCX originator 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. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (https://rapidlasso.de/laszip/) Processing notes: 2025-07-01T13:43:48 NOAA Office for Coastal Management coastal.info@noaa.gov processor
