Seabed Habitat Solitary Islands Marine Park and Commonwealth Marine Reserve (South)
Digitised habitat layers for the southern section of the Solitary Islands Marine Park and Solitary Islands Marine Reserve, NSW. Includes reef and unconsolidated seafloor types as interpreted from a series of high resolution bathymetry and backscatter data obtained during swath surveys 2005-2012.

- Statement
- Swath acoustic data was collected with a GeoSwath interferometric sidescan by the New South Wales Office of Environment and Heritage. The geo-referenced depth and sidescan backscatter data, when processed is used to digitise areas of rocky reef by hand at a constant scale of 1:2,000 or finer using a combination of the bathymetry and backscatter, with a minimum mapping unit of approximately 20 m depending on the complexity of the seafloor features. For the habitat layer the geometry of this layer was repaired using the Repair Geometry tool within ArcToolbox, cleaned using ETGeowizards, and dissolved using ArcToolbox. Recent updates of the layer involved using the Update and Union tools within ArcGIS to update areas of swath that had been changed since the last version of the habitat layer. Topology was built and there were no overlaps present. The attribute table was edited to simplify the data and remove unnecessary information. An intuitive estimate of attribute accuracy is provided here. The horizontal precision of hand digitised polygons are generally better than 15m. Polygons were hand digitised at a scale of no less than 1:2500 and based around the identification of bins (2x2m) as either data or no data. Due to the coarseness of hand digitising some data gaps may be included within the polygon and small areas of data excluded from the polygon. Overall map accuracy was calculated to be 81.56%, using video groundtruthing data compared to digitised polygons. User accuracy for reef areas was slightly higher, at 84.05%, while accuracy for Non-reef areas was 79.36%. The Tau coefficient (T) was 0.69.
