Modelled vector layers (shapefiles) of spatial extent of aquaculture potential in the Dorset East Devon Fisheries Local Action Group area, 2018-2019

Polygon shapefiles converted from modelled raster layers of aquaculture potential, with values ranging between 0 (representing no potential) and 1 (representing full potential). The underlying raster layers were derived by combining conservation, legislative, human infrastructure features and activity boundaries with environmental requirements for specific aquaculture species/system combinations. The polygon boundaries delineate aquaculture potential areas with a modelled raster classification of 0.5 or higher (i.e. 50% of threshold values are optimum for the specific species/system combination)....
