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 data were acquired from 20221114 - 20230212. 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 TX2201 project instructions. This data set also includes lidar intensity values and encoded RGB image values. The data was developed based on a horizontal projection/datum of NAD83 (2011), UTM14N (EPSG 6343), meters and vertical datum of NAVD88 (GEOID18), meters. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. purpose: 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. credit: We request that you credit the National Oceanic and Atmospheric Administration (NOAA) when you use these data in a report, publication, or presentation.

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. The resulting data set is referred to as the raw LiDAR data. dateTime: DateTime: 2023-02-28T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: 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 dateTime: DateTime: 2024-09-18T00:00:00 processor: (CI_ResponsibleParty) organisationName: Anchor: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: 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.
