The data was acquired April 9, 2017. The data includes topobathy data in LAS 1.2 format classified as created, unclassified (1); ground (2); topographic noise (7); bathymetric noise (22); water column (25); bathymetric bottom (26); water surface (27); International Hydrographic Organization S-57 object, not otherwise specified (30) in accordance with project specifications. The project consists of approximately 34 square miles of data along the shores of St. Jeromes Creek. This dataset contains 342 500 m x 500 m lidar tiles. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: St. Jeromes Creek has been identified as having critical topographic and bathymetric data gaps by NOAA. This lidar data will fill those critical gaps. credit: We request that you credit the National Oceanic and Atmospheric Administration (NOAA) when you use this data in a report, publication, or presentation.

All delivered lidar data is referenced to: Horizontal Datum-NAD83 (2011) epoch: 2010 Projection-UTM Zone 18 North Horizontal Units-meters Vertical Datum-NAD83 (2011) epoch: 2010 Vertical Units-meters This dataset encompasses 342 500 m x 500 m lidar tiles. Both green lidar data and NIR lidar data were acquired. NOAA 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. Dewberry received the calibrated green and NIR data and verified complete coverage. Relative accuracy of the green swaths compared to overlapping and adjacent green swaths as well as the relative accuracy of green swaths compared to overlapping and adjacent NIR swaths was verified through the use of Delta-Z (DZ) orthos created in GeoCue software. Intraswath or within a swath relative accuracy was verified using Quick Terrain Modeler. Profiles of elevated planar features, such as roofs, were used to verify horizontal alignment between overlapping swaths. Dewberry used algorithms in TerraScan to create the intial ground/submerged topography surface. Dewberry created 2-D breaklines by digitizing breaklines in a 2-D environment using intensity imagery as a reference. Dewberry used the 2-D breaklines to classify the bathymetric bottom and ground points properly in TerraScan. All lidar data was peer-reviewed. Dewberry's QAQC also included creating void polygons for use during review. All necessary edits were applied to the dataset. GeoCue software was used to update LAS header information, including all projection and coordinate reference system information. The final lidar data is in LAS format 1.2 and point data record format 3. The final classificaton scheme is as follows: 1-Unclassified 2-Ground 7-Topographic Noise 22-Bathymetric Noise 25-Water Column 26-Bathymetric Bottom 27-Water Surface 30-International Hydrograpic Organization (IHO) S-57 Object All data was then verified by an Independent QC department within Dewberry. The independent QC was performed by separate analysts who did not perform manual classification or editing. The independent QC involved quantitative and qualitative reviews. dateTime: DateTime: 2019-02-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: National Geodetic Survey role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received 616 files in las 1.2 format. The files contained lidar intensity and elevation measurements for the project area. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. Converted from UTM Zone 18 coordinates to geographic coordinates 3. Sorted by gpstime 4. Compressed the data using laszip processStep: (LI_ProcessStep) description: 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) Processing notes: dateTime: DateTime: 2023-08-01T06:44:08 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
