The data were acquired from from November 3, 2022 through March 5, 2023. The data includes topobathy data in an LAS 1.4 format file classified as unclassified (1), ground (2), low noise (7), topo water surface (9), high noise (18), bathymetric point (40), bathymetric water surface (41), synthetic derived water surface (42), and submerged object (43), in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: This data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne lidar. credit: We request that you credit the National Oceanic and Atmospheric Administration (NOAA) when you use these data in a report, publication, or presentation.

All las are referenced to the following: Horizontal Datum-NAD83 (2011) epoch: 2010 Projection-UTM Zone 18 North Horizontal Units-meters Vertical Datum-Ellipsoidal Vertical Units-meters This dataset is tiled into 500m x 500m tiles. Both green lidar data and NIR lidar data were acquired. Woolpert acquired, calibrated, and performed the refraction correction of the lidar data. Light travels at different speeds in air versus water and its direction of travel or angle is changed or refracted when entering the water column. The refraction correction process corrects for this difference by adjusting the depth (distance traveled) and horizontal position (change of angle/direction) of the lidar data acquired within water. Relative accuracy of the swaths compared to overlapping and adjacent swaths was verified through the use of Delta-Z (DZ) orthos created in LASTools software. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths. Algorithms in TerraScan was used to create the intial ground surface. All lidar data was peer-reviewed. QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. LASTools was used to update LAS header information, including all projection and coordinate reference system information. The final lidar data is in LAS format 1.4 and point data record format 6. dateTime: DateTime: 2024-07-10T00:00:00 processor: (CI_ResponsibleParty) organisationName: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received files in laz format. The files contain lidar elevation and intensity measurements of the Chesapeake VA2203 block. The LiDAR data were in NAD83(2011) UTM Zone 18N 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 18 to geographic coordinates 2.
