  • This service represents the National Digital Elevation Model (DEM) 1 Second Percentage Slope product, derived from the National DEM SRTM 1 Second. Slope measures the inclination of the land surface from the horizontal. Percent slope represents this inclination as the ratio of change in height to distance.

  • The Marine Survey Multibeam Bathymetry Web Map Service contains the highest-resolution multibeam bathymetry grids available for download on Geoscience Australia's website. These bathymetry grids were collected over numerous multibeam survey programs conducted in Australian mainland and Antarctic waters by both Geoscience Australia and our collaborators. Layers are grouped by survey or region and where available include both the Geoscience Australia and vessel survey identification numbers that contributed to the bathymetry grids. Bathymetry grids have been rendered over a rainbow colour-ramp with minimum and maximum depth values unique for each survey. These values are specified in each survey's layer description. The resolution of each bathymetry grid is also specified in each survey's layer description

  • This web service displays the results of a marine survey conducted by Geoscience Australia in Commonwealth waters of the north-eastern Browse Basin (Caswell Sub-basin) between 9 October and 9 November 2014. The additional codes GA-0345 and GA-0346 refer to Geoscience Australia (GA) internal codes and TAN1411 is the vessel survey number given by the RV Tangaroa for 2014.

  • This web service combines two surveys GA-4415 and GA-0348. The Casey Station Bathymetry survey displays one seamless bathymetry grid of 1m resolution. Further details of the data lineage can be found with the associated database. This web service is published with the permission of the CEO, Geoscience Australia.

  • The Clip and Zip tool takes an input polygon extent as WKT input and clips required featureclasses listed. The data is referenced from its own database with all layers projected to 4326 spatial reference. The output is a zipped file geodatabase with a copyright text file included.

  • 3D seismic survey polygon area. The data within this layer only contains high level information regarding the individual surveys, not the actual survey. NOPIMS data is supplied by the petroleum industry. NOPIMS data is only offshore petroleum that belongs to the Commonwealth. A two dimensional (3D) seismic survey is a method of exploration used to capture seismic data beneath Earth's surface. 3D seismic provides continuous information of the subsurface within the extent of the survey. transect line of information in the survey. This method sends energy waves into the Earth to detect changes in the subsurface geology. The rock formations in the subsurface geology reflect the waves back to detector, where they are captured over the desired timeframe and converted into a seismic image. Depending on the age the survey was conducted will depend on the method used to capture the information. Older records more likely used explosives to capture seismic data whereas newer surveys use compressed air.

  • The Criteria Assessment tool takes the input path or area created by the user and the input variables chosen to generate a heat map surface, KML surface, KMZ surface and PDF Report. This service is specifically for use within the Carbon Capture and Storage application.

  • The Carbon Infrastructure Assessment and Planning (CIAP) Tile Index System is a set of nested tile indexes from 1:25000 through to 1:10000000 scales based on the ICSM map indexes. The product has been generated for use at national scale based in GDA94 projection. This product supports the best available information system (BAIS)as used by the CIAP application.

  • The service contains the Australian Coastal Geomorphology Landform Subtype Classifications, used to support a national coastal risk assessment. It describes the location and extent of landform subtypes identifiable at scales between 1:25,000 and 1:10,000. It also provides further detail to the Landform Type, with particular reference to feature stability (e.g. dune types) and mobility (e.g. channel types). It is cached service with a Web Mercator Projection.

  • The service contains the Australian Coastal Geomorphology Scale Guide, used to support a national coastal risk assessment. It includes the extents of various reclassified costal mapping products. It is cached service with a Web Mercator Projection.
