The Oceanic Shoals survey (SOL5650, GA survey 339) was conducted on the R.V. Solander in collaboration with Geoscience Australia, the Australian Institute of Marine Science (AIMS), University of Western Australia and the Museum and Art Gallery of the Northern Territory between 12 September - 5 October, 2012. This dataset comprises an interpreted geomorphic map. Interpreted local-scale geomorphic maps were produced for each survey area in the Oceanic Shoals Commonwealth Marine Reserve (CMR) using multibeam bathymetry and backscatter grids at 2 m resolution and bathymetric derivatives (e.g. slope; 1-m contours). Six geomorphic units; bank, depression, mound, plain, scarp and terrace were identified and mapped using definitions suitable for interpretation at the local scale (nominally 1:10 000). Maps and polygons were manual digitised in ArcGIS using the spatial analyst and 3D analyst toolboxes. For further information on the geomorphic mapping methods please refer to Appendix N of the post-survey report, published as Geoscience Australia Record 2013/38: Nichol, S.L., Howard, F.J.F., Kool, J., Stowar, M., Bouchet, P., Radke, L., Siwabessy, J., Przeslawski, R., Picard, K., Alvarez de Glasby, B., Colquhoun, J., Letessier, T. & Heyward, A. 2013.

The Cobar Goldfield South 1;10,000 regolith-landform map illustrates the distribution of regolith materials and the landforms on which they occur, described using the RTMAP scheme developed by Geoscience Australia

The Nauru GIS was created for both broad scale and detailed planning of rehabilitation and secondary mining. However, it also contains other datasets (e.g buildings, roads, storage tanks etc) which although are not error free may be of interest and prove useful for other purposes. The primary components for this product were to provide: ? geocorrected images (Orthophotography), ? Digital Elevation Models, ? data integration and system development ? training. This product was designed and compiled by the Australian Geological Survey Organisation on behalf of the Nauru Rehabilitation Corporation and the Nauru Phosphate Corporation, Republic of Nauru. The project commeced in November 1999, following a scoping report written in March 1999 and was completed by June 2000. This product is referred to as the Level 1 ArcExplorer GIS as described in the Scoping and Progress Reports and the final system documentation.
