Vlaming Shelf reef polygons

Vlaming Shelf reef polygons were manually digitized from multibeam echosounder datasets collected on marine survey GA0334 in March/April 2012. Reef areas were defined as exposed, hard substrate that are often raised above the surrounding seafloor. They were mapped using bathymetry and backscatter data along with bathymetric derivatives including; slope, hillshaded bathymetry and contours. Features were mapped at a scale of 1:10 000.
