Full description

Jervis Bay Reef Polygons were digitised from the Multibeam bathymetry datasets of Jervis Bay. Reef areas were defined as seabed hard substrate that are often raised from the surroundings flat sedimentary seabed. They were identified and mapped relatively easily on hillshaded bathymetry layers.

Statement: The multibeam bathymetry layers of the Jervis Bay area were displayed in ArcMap. The hillshaded layers of these multibeam datasets were generated using an ArcGIS Desktop Tool. Overlaying the semi-transparent bathymetry layers on top of the hillshaded layers provides 3-D DTM effect. The reef areas were then identified and digitised on the display using Editing tools. The subsequent QC process has made some changes to the reef polygons.
