The data is organized in such a way that the data can be reasonably streamed over the internet, pulling only the points you need. EPT files can be queried to return a subset of the points that give you a representation of the area. As you zoom further in, you are requesting higher and higher densities. A dataset in EPT will contain a lot of files, however, the ept.json file describes all the rest. The EPT file can be used in Potree and QGIS to view the point cloud. download https://coast.noaa.gov/lidar/viewer/v/noaapotree.html?r=https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/entwine/geoid18/14653/ept.json WWW:LINK-1.0-http--link 3D Viewer (Potree NOAA) Link to view the point cloud, using the Entwine Point Tile (EPT) format, in the 3D Potree viewer. download These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using a Chiroptera 5 system. The data were acquired from 20240415 - 20240518. The data includes topobathy data in an LAS 1.4 format file classified as unclassified (1), ground (2), low noise (7), water surface (9), high noise (18), bathymetric point (40), water surface (41), derived water surface (42), submerged object (43), International Hydrographic Organization (IHO) S-57 object (44), submerged aquatic vegetation, and bethymetric bottom temporal changes from varying lifts, not utilized in bathymetric point class (65) in accordance with the instructions in the FL2313 project instructions. This data set also includes lidar intensity values and encoded RGB image values. he data was developed based on a horizontal projection/datum of NAD83 (2011), UTM17N (EPSG 6346), meters and vertical datum of NAVD88 (GEOID18), meters. This lidar data was required by National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS), Remote Sensing Division Coastal Mapping Program (CMP) to enable accurate and consistent measurement of the national shoreline. The CMP works to provide a regularly updated and consistent national shoreline to define America's marine territorial limits and manage coastal resources.

The vertical accuracy is 0.058 at 1 sigma. PRE-PROCESSING STAGE - LiDAR, GPS and IMU data are processed together using Leica's LPP software. The LiDAR data set for each flight line is checked for project area coverage and LiDAR post spacing is checked to ensure it meets project specifications. The LiDAR collected at the calibration area is used to correct the rotational, atmospheric, and vertical elevation differences that are inherent to LiDAR data. Intensity raster is generated to verify that intensity was recorded for each LiDAR point. LiDAR data is transformed to the specified project coordinate system. By utilizing the ground survey data collected at the calibration site and project area, the LiDAR data is vertically biased to the ground. This calibration is done in Strip AlignComparisons between the biased LiDAR data and ground survey data within the project area are evaluated and a final RMSE value is generated to ensure the data meets project specifications. LiDAR data in overlap areas of project flight lines is removed and data from all swaths is merged into a single data set. The data set is trimmed to the digital project boundary including an additional buffer zone, which is typically about 50 meters. 2023-02-28T00:00:00 National Geodetic Survey processor CLASSIFICATION STAGE - The raw LIDAR data is processed through a minimum block mean algorithm and points are classified as either bare earth or non-bare earth. User developed "macros" that factor mean terrain angle and height from the ground are used to determine bare earth point classification. The next phase of the surfacing process is a 2D edit procedure that ensures the accuracy of the automated feature classification. Editors use a combination of imagery, intensity of the LiDAR reflection and tin-editing software to assess points. If required, the LiDAR data is filtered as necessary, using a quadric error metric to remove redundant points to generate a keypoint class. 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. When other classifications and derived products are required, various applications and proprietary algorithms are used to meet each customer's unique requirements. The following software was used for the validation: 1) RiProcess 1.8.3, RiWorld 5.0.2, RiAnalyze 6.2, RiServer 1.99.5; and 2) Fugro proprietary software 2024-09-30T00:00:00 National Geodetic Survey processor Classified LAS Deliverable - The topo-bathy merged point cloud data will be delivered in fully compliant LAS v1.4 format, Point Record Format 6, with Adjusted Standard GPS Time at a precision sufficient to allow unique timestamps for each pulse. Correct and properly formatted georeference information as OGC WKT will be assigned in all LAS file headers in accordance with LAS specification Version 1.4 - 1.4-R15. Each tile will have File Source ID set to zero (0). The Point Source ID will match to the flight line ID in flight trajectory files. Intensity values are included for each point. 2024-09-30T00:00:00 National Geodetic Survey processor The NOAA Office for Coastal Management (OCM) received files in laz format. The files contain lidar elevation and intensity measurements. The LiDAR data were in NAD83(2011) UTM Zone 17N coordinates and ellipsoid elevations in meters. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Converted from UTM Zone 14 to geographic coordinates 2. Sorted by gps time and 3. reclassified point data. The final classification scheme is as follows. 1 - Unclassified 2 - Ground 7 - Low Noise 9 - Water Surface 18 - High Noise 40 - Bathymetric Point 41 - Water Surface 42 - Derived Water Surface 43 - Submerged Object 44 - International Hydrographic Organization (IHO) S-57 object 2026-07-30T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Acquisition and Processing Fugro USA Land, Inc. originator
