Groundwater Dependent Ecosystems (GDE)

The National Atlas of Groundwater Dependent Ecosystems presents the current knowledge of groundwater dependent ecosystems across Australia. It displays ecological and hydrogeological information on known groundwater dependent ecosystems and ecosystems that potentially use groundwater. The Atlas is a tool to assist the consideration of ecosystem groundwater requirements in natural resource management, including water planning and environmental impact assessment.

National Catchment Boundaries v1.4

The National Catchment Database is a linked set of spatial layers and associated attribute tables describing key elements of the surface water hydrology of the Australian continent at a map scale of about 1:250,000. It is built upon the representation of surface drainage patterns provided by the GEODATA national 9 second Digital Elevation Model (DEM) Version 3 (ANU Fenner School of Environment and Society and Geoscience Australia, 2008).

Geofabric Catchments

The Australian Hydrological Geospatial Fabric (Geofabric) is a specialised Geographic Information System (GIS). It registers the spatial relationships between important hydrological features such as rivers, water bodies, aquifers and monitoring points.

Digital Topographic Mapping Data

Our topographic data is available for use in GIS applications, in the following scales which reflect their level of accuracy and best scale for use. The smaller the scale (i.e. 1:250 000 is a smaller scale than 1:100 000), the fewer features are depicted in the data and naturally they will be less spatially accurate. Geodata is vector data.

Interactive Maps

The surface hydrology dataset provides a seamless surface layer for Australia at a nominal scale of 1:250,000. It consists of lines, points and polygons representing natural and man-made features such as water courses, lakes, dams and other water bodies. The natural water course layer consists of a linear network with a consistent topology that provide directional flow paths through the network for hydrological analysis. This network was used to produce the National 9 second Digital Elevation Model (DEM) of Australia. It also provides information on naming, hierarchy and perennially.

PSMA Transport and TopographyTM

The Transport and Topography dataset is underpinned by a road centreline layer of over 2.7 million kilometres of roads, together with more than 30 feature types within transport, hydrology and green space themes. Roads - a national coverage of network roads at all levels within Australia. Everything from major highways to outback tracks, new roads and changes to current roads. Airports - all aspects of airport infrastructure within Australia, including all airports from international to local landing strips.
