  • 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

  • The Surface Geology web map service provides two seamless national coverages of Australian bedrock and surficial geology, compiled at 1:1 million scale (displays only at scales less than 1:1500000), and 1:2.5 million scale (displays only at scales greater than 1:1500000). It also contains 1:5 million scale geological regions and metamorphic geology. The service represents outcropping or near-outcropping bedrock units, and unconsolidated or poorly consolidated regolith material covering bedrock.

  • The Tasselled Cap Wetness (TCW) percentage exceedance composite represents the behaviour of water in the landscape, as defined by the presence of water, moist soil or wet vegetation at each pixel through time. The summary shows the percentage of observed scenes where the Wetness layer of the Tasselled Cap transform is above the threshold, i.e. where each pixel has been observed as ‘wet’. Areas that retain surface water or wetness in the landscape during the dry season are potential areas of groundwater discharge and associated GDEs. The TCW exceedance composite was classified into percentage intervals to distinguish areas that were wet for different proportions of time during the 2013 dry season. Areas depicted in the dataset have been exaggerated to enable visibility.

  • The WOfS summary statistic represents, for each pixel, the percentage of time that water is detected at the surface relative to the total number of clear observations. Due to the 25-m by 25-m pixel size of Landsat data, only features greater than 25m by 25m are detected and only features covering multiple pixels are consistently detected. The WOfS summary statistic was produced over the McBride and Nulla Basalt provinces for the entire period of available data (1987 to 2018). Pixels were polygonised and classified in order to visually enhance key data in the imagery. Areas depicted in the dataset have been exaggerated to enable visibility.

  • Online resource API to AusPIX-enable (DGGS enable) spatial datasets for smaller areas of Australia. The main API will accept your geojson file, complete with data attributes, AusPIX DGGS enable it, and return as a download, the finished output. Download includes the features and attributes the source file had in it so the data is actually AusPIX enabled. Both manual and machine readable components are available. A further (2nd) API "test map" API allows the user to draw points, lines, or polygons on the map, and have the area of interest AusPIX DGGS enabled as a returned list of cells. Potentially data for these cells can be searched for in AusPIX Data Integration by Locality tables or using the AusPIX linked Data API.
