2022 NOAA NGS Ortho-rectified 4-band MHW Mosaic: Gilchrist (TX) to Isles Dernieres Barrier Islands Refuge (LA)

>Product: This data set is single point georeferenced, radiometrically corrected digital imagery. The 4 band imagery was collected at 16 bits per band (stored as a standard 8 bit per band geotiff) with the following band order: red, green, blue, infrared. Geographic Extent: Shoreline in Texas and Louisiana along the Gulf of America, totaling 236 sq miles. Dataset Description: The LA2207 project called for the planning, acquisition, processing, and derivative products of imagery data to be collected at a ground sample distance (GSD) of 25 cm. The data were developed based on a horizontal projection/datum of NAD 1983 2011 UTM Zone 15N, Meter. Imagery data were formatted to 4 stereo strips. Ground Conditions: Imagery was collected in fall/winter 2022, while rivers were at or below normal levels. This is flown at the Mean High Water Mark

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.
