Title: 2017 NOAA NGS Ortho-rectified Oblique Imagery of the Gulf Coast
Short Name: 2017_ngs_gcob_rgb
Status: Completed
Publication Date: 2017-08-09
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.

Notes:

11530

Supplemental Information:

The ground sample distance (GSD) for each pixel is ~0.30 m.

Data Quality

Horizontal Positional Accuracy:

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 Value: 10 meters, Test that produced the value: Accuracy has not been assessed.

Completeness Measure:

Cloud Cover: 5

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.

Conceptual Consistency:

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.

Process Steps

Process Step 1

CC ID: 634665
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.
