Seagrass map, Cat Island, Mississippi, 2023

This product depicts the spatial coverage of seagrass beds from 0.5-m color-infrared orthoimagery for Cat Island, Mississippi from early fall of 2023. Specifically, the map includes presence and absence of seagrass beds within a potential seagrass extent that was based on topobathymetric data. A minimum mapping unit of 4 square meters was used for this mapping effort. We did not have complete coverage for this map due to cloud shadows or lack of imagery. Areas that were not classified but were expected to have potential seagrass coverage based on water depth (i.e., less than or equal to 3m depth relative to the North American Vertical Datum of 1988) were classified as "9999."
