Includes bathymetry, eelgrass buffer of 25ft, hard substrate, Shellfish Management Areas, and vessel traffic. This file geodatabase contains vector layers that were created from the input and final rasters of an oyster aquaculture suitability model for South Coast, MA. It includes the layers listed below. SouthCoast_Offshore is a polygon of the study region boundary. The others, except SuitabilityModel, each represent a grid with 100x100 foot cells that are coded with a value from 0 - 4 to represent the factor's suitability. Cells with 0 represent a disqualifying factor and cells with 4 represent an optimal factor. Values of 1, 2, and 3 are not disqualifying but represent various degrees of suitability. When multiplied all together they produce the layer SuitabilityModel which has 100x100 foot cells with values between 0 and 1024.<div><br /></div><div>The input layers were created from the following original datasets:</div><div><ul><li>Bathymetry data from the <a href='https://www.sciencebase.gov/catalog/item/5a4649b8e4b0d05ee8c05486' target='_blank' rel='nofollow ugc noopener noreferrer'>USGS</a></li><li>Seafloor data from <a href='https://www.mass.gov/info-details/massgis-data-moris-layers-from-coastal-zone-management' target='_blank' rel='nofollow ugc noopener noreferrer'>MassGIS via CZM</a></li><li>Vessel traffic data from the <a href='https://www.arcgis.com/home/webmap/viewer.html?url=https://coast.noaa.gov/arcgis/rest/services/MarineCadastre/2017VesselTransitCounts_AllVessels/MapServer&amp;extent=-100,40&amp;level=4' target='_blank' rel='nofollow ugc noopener noreferrer'>Marine Cadastre</a></li><li>Eelgrass Beds data from the <a href='https://www.northeastoceandata.org/files/metadata/Themes/Habitat.zip' target='_blank' rel='nofollow ugc noopener noreferrer'>Northeast Ocean Data Portal</a></li><li>Shellfish Management Area data from the <a href='https://www.northeastoceandata.org/files/metadata/Themes/Aquaculture.zip' target='_blank' rel='nofollow ugc noopener noreferrer'>Northeast Ocean Data Portal</a></li></ul><div>The original SuitabilityModel layer shows the best potential areas for new oyster farms in the region.</div></div> Marine Cadastre, MassGIS, Northeast Ocean Data Portal, USGS No limitations.
