  • This web service provides access to the Waste Management Facilities dataset and presents the spatial locations of all the known waste management, recycling and reprocessing facilities within Australia, all complemented with feature attribution.

  • 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 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 Joseph Bonaparte Gulf survey (SOL4934, GA survey #0322) was conducted on the R.V. Solander between 27 August and 24 September 2009 in collaboration with staff from the Australian Institute of Marine Science (AIMS) and the Northern Territory Government. The survey was completed under a Memorandum of Understanding between GA and the AIMS and represents the second of three surveys planned under this agreement. The survey obtained detailed geological (sedimentological, geochemical, geophysical) and biological data for the banks, channels and plains to establish the late-Quaternary evolution of the region and investigate relationships between the physical environment and associated biota for biodiversity prediction. Underwater video footage and still images were collected from 46 stations, although quality varies among transects and some still images were not of suitable quality for analysis. In addition, shipboard photographs were taken of barcoded biological specimens. Video and image files or associated parent folders are named according to station number, followed by gear code (TV or CAM = same underwater camera system) and then the deployment number. For example 48CAM35 represents a video transect from Station 48 that was the 35th video transect on the survey.

  • This web service provides access to the Major Power Stations, Transmission Substations and Electricity Transmission Lines datasets. These datasets present the spatial locations of all known features in Australia.
