This data set contains ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative. The source imagery was acquired 20131120 with an Applanix Digital Sensor System (DSS). The original images were acquired at a higher resolution than the final ortho-rectified mosaic.

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.; Quantitative Value: 1.5 meters, Test that produced the value: These data are accurate with a 95% circular error confidence level.
Cloud Cover: 0
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.
All rectified images were loaded in Global Mapper 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 and then corrected using Photoshop.

Mosaic's were generated from the color ortho-rectified imagery using OrthoVista. Pyramids are built in during this step. Mosaic data have not been histogram stretched and only minimal color balancing has been performed. The images are in 8 bit RGB. 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 2.5 km by 2.5 km squares.
