Description:
Abstract:
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 from 20170401 - 20170419 with an Applanix Digital Sensor System (DSS). The original images were acquired at a higher resolution to support the final ortho-rectified mosaic.
Purpose:
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.
Supplemental_Information: The ground sample distance (GSD) for each pixel is ~0.30 m.

Data_Quality_Information:
Logical_Consistency_Report:
All rectified images were loaded in QGIS to view the entire project area for tone differences, complete coverage, warping/smearing imagery due to inaccurate DEM, and any other obvious problems.
Completeness_Report:
The extent of image coverage is limited to the area near and around the shoreline and therefore may not include all areas within the bounding coordinates.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The accuracy's have not been assessed. The absolute horizontal positions should be in the 5-10 meter range in areas with little or no topographic relief.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: 10
Horizontal_Positional_Accuracy_Explanation: Accuracy has not been assessed.

Process_Step:
Process_Description:
Mosaic's were generated from the color ortho-rectified imagery using Enblend, ExifTool, Imagemagick, Python and GDAL. 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. Bilinear resampling method was used to create the final ortho-rectified mosaic. Original image tiles are ~2.5 km by ~2.5 km squares.
