These files contain classified topographic and bathymetric lidar data as unclassified valid topographic data (1), and valid topographic data classified as ground (2), and valid Bathymetric data (29) 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 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 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.
These data were collected as a part of the NCMP to depict the elevations above and below the water in the New Jersey coastal zone.

Accuracy
These data are not attributed. | Quantitative Value: None | Quantitative Test Explanation: These data are not attributed.
Horizontal Positional Accuracy
The data positions were obtained using post processed KGPS methods. The horizontal accuracy of CZMIL in the joint topo/bathy mode of operation is +/- 1 m, 2 sigma.; Quantitative Value: 1.0 meters, Test that produced the value: +/- 1 m, 2 sigma
Vertical Positional Accuracy
Topo data - 19.6 cm @ 95% confidence level (10 cm RMSE). Bathy shallow FOV data - SQRT((0.25^2)+((0.0075d)^2)) meters at @ 95% confidence level. Bathy deep FOV data - SQRT((0.30^2)+((0.013d)^2)) meters @ 95% confidence level (d is depth).; Quantitative Value: 0.15 meters, Test that produced the value: +/- 15 cm, 2 sigma
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 CZMILs 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.
2014-06-18T00:00:00
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 algorithms 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).
2014-06-30T00:00:00
The NOAA Office for Coastal Management (OCM) received the topographic/bathymetric files in LAS format from USACE. The files contained lidar easting, northing, elevation, intensity, return number, etc. The data was received in Geographic Coordinates (decimal degrees). The vertical coordinates were referenced to NAVD88 in meters using the Geoid12a model. OCM performed the following processing for data storage and Digital Coast provisioning purposes:
1. Class 29 points (bathymetry) were reclassified to Class 11 (bathymetry) to fit OCM DAV class scheme.
2. LAS files were converted LAZ compressed format and converted from orthometric values to ellipsoidal values.

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 (laszip.org)
