The project AOI covers approximately 161.5 square kilometers, and includes the area from Whitefish Point to Bay Mills, MI in Eastern Lake Superior, the eastern portion of which falls within and EPA's St. Marys River area of concern. Lidar was collected in August 2023. Tetra Tech established 4 ground control points that were used to calibrate the lidar to known ground positions. 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: The purpose of this proposed bathymetric lidar collection is to build upon existing high resolution coastal and nearshore bathymetry to expand coverage and support benthic habitat mapping in critical priority areas. The importance of high resolution bathymetry in this area of Lake Superior was also identified by multiple regional partners through various need assessments and reporting mechanisms including the Great Lakes prioritization study. credit: National Oceanic and Atmospheric Administration, Office for Coastal Management The custom download may be cited as National Oceanic and Atmospheric Administration (NOAA) Digital Coast Data Access Viewer.

For every individual lidar swath, all 9 channels of the SuperNova were calibrated in unison. The only differentiation being forward vs backward laser look angles with respect to flight direction. Any swath edge or tail mismatches were rectified using two iterative rounds of swath alignment. Calibrated swaths were shifted vertically to the four ground control points (GCPs) for improved absolute accuracy. A control report for final calibrated LAS was run in TerraScan after the points were shifted. The average Dz compared to the GCPs revealed a mean value of 0.034 m with a Standard Deviation and the NVA RMSE of 0.051 m and 0.044 m respectively. result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: These LAS data files include all data points collected.

This software uses machine learning to identify water surface and bathymetric bottom from the waveforms, then classifies the point cloud as such. Data are processed on a per mission basis then exported to raw, uncalibrated swaths in LAS 1.4 format. Before moving on to subsequent processing steps, coverage and density were reviewed according to project specifications. Reasonable effort was made to identify candidate areas for reflights in an attempt to obtain better bathymetric bottom coverage. The calibrated point cloud was processed through a series of automated classification routines to obtain consistent water surface and ground classes. Additionally, excessive noise was moved to the appropriate classes in order to create a cleaner point cloud product. Tetra Tech completed automated and manual editing of the lidar dataset, performed a QA/QC review, and created final products for delivery. dateTime: DateTime: 2023-10-20T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) processed 983 LAS files collected by Tetra Tech. The files were in UTM Zone 16N NAD83 meters coordinates and the elevations were in NAVD88 (GEOID18) meters. The LAS files had these classifications: 1 = unclassified; 2 = ground (or Bare Earth); 7 = low point (withheld); 18 = high noise (withheld); 40 = bathymetric bottom, 41 = water surface; 42 = derived water surface (synthetic); 43 = submerged object; 45 = water column. NOAA OCM processed the 1, 2, 7, 18, 40, 41, 42, 43 and 45 point classes to the Digital Coast Data Access Viewer (DAV). OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Internal OCM scripts were run to check the number of points by classification and by flight ID and the gps, elevation, and intensity ranges. 2. Internal OCM scripts were run on the laz files to: a. Convert from orthometric (NAVD88) elevations to ellipsoid elevations using the GEOID18 model b. Convert from UTM Zone 16N NAD83 meters coordinates to geographic coordinates c. Assign the geokeys, to sort the data by gps time and zip the data to database and to AWS S3. dateTime: DateTime: 2026-03-11T00:00:00 processor: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor source: (LI_Source) sourceCitation: (CI_Citation) title: LAZ Files date: (missing) citedResponsibleParty: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management role: (CI_RoleCode) originator processStep: (LI_ProcessStep) description: The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. dateTime: DateTime: 2026-03-30 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
