69582 Data Set Published / External 47843 NGS Imagery Project Completed 2023 This data set contains 4-band ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative. The source imagery was acquired from 20220804 - 20220807 with a Digital Sensor System (DSS) Version 6. The original images were acquired at a higher resolution to support the final ortho-rectified mosaic. Ortho-rectified mosaic tiles 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. The ground sample distance (GSD) for each pixel is 0.25 m. The imagery was acquired below mean high water.

OS Independent The horizontal positional accuracy and the assurance of that accuracy are dependent upon the accuracy of the data inputs to the rectification process. These data inputs include the digital elevation model (DEM), accuracy of control, and methodology used to georeference the imagery that meet NOAA's Coastal Mapping Program standards. Horizontal_Positional_Accuracy_Value: 1.5 Horizontal_Positional_Accuracy_Explanation: These data are accurate with a 95% circular error confidence level. All rectified images were loaded into a GIS package to view the entire project area for tone differences, complete coverage, warping/smearing imagery due to inaccurate DEM, and any other obvious problems. All final tiles are reviewed for artifacts, unblended seam-lines and warps or smears. The extent of image coverage is limited to the acquired flight lines which were planned to map the shoreline and therefore may not include all areas within the bounding coordinates. Processing Organization National Geodetic Survey Originator 1 Mosaic's were generated from 4-band (red, green, blue, near-infrared) ortho-rectified imagery. Mosaic data have not been histogram stretched and only minimal color balancing has been performed. The images are in 8 bit RGBI. The DEM source is 30 meter posting USGS NED. Cubic convolution resampling method was used to create the final ortho-rectified mosaic. Original image tiles are 3.0 km by 3.0 km squares. 2023-01-24T00:00:00 Organization National Geodetic Survey NGS https://ror.org/02f762h70 1315 East-West Hwy Silver Spring MD 20910 https://geodesy.noaa.gov/ 71924 Entity gov.noaa.nmfs.inport:69582 Maryellen Sault 2023-04-11T18:52:19 SysAdmin InPortAdmin 2026-03-04T19:17:17 2024-01-11 National Geodetic Survey NGS 1002 Public No No 2022-04-01 1 Year 2023-04-01
