Australia's future safety, prosperity and sustainability depends on making informed policy and investment decisions that meet the needs of today, and the decades ahead. Digital elevation data which describes Australia's landforms and seabed is crucial for addressing issues relating to the impacts of climate change, disaster management, water security, environmental management, urban planning and infrastructure design.
The national geocoded dataset is a data aggregation from multiple jurisdiction sources which depicts national and accurate information for geocoded addressing.
Mesh Blocks (MBs) are the smallest geographical area defined by the ABS. They are designed as geographic building blocks rather than as areas for the release of statistics themselves. All statistical areas in the Australian Statistical Geography Standard (ASGS), both ABS and Non ABS Structures, are built up from one or more MBs.
The National groundwater dataset is derived from multiple inputs aggregated together to provide a national coverage for all of Australia.
The dataset provides a nationally consistent set of groundwater boundaries and properties including aquifer boundaries, geometry, salinity, yield and hydraulic conductivity.
The national groundwater dependent ecosystems is a dataset aggregated from different sources to produce a national coverage over all of Australia.
Groundwater Dependent Ecosystems (GDE) is ecological and hydrogeological information on known groundwater dependent ecosystems and ecosystems that potentially use groundwater.
The National groundwater bores is a national dataset aggregated from numerous inputs to produce a consistent coverage over Australia for groundwater bores.
The groundwater bores (including monitoring, irrigation and commercial bores) and associated lithology, construction and hydrostratigraphy logs. The National Aquifer Framework has been used to standardise the hydrogeological unit terminology for this dataset.
The term Territorial Sea Baseline (TSB) refers to the line from which the seaward limits of Australia's Maritime Zones are measured. These include the breadth of the territorial sea; the seaward limits of the contiguous zone, the exclusive economic zone and, in some cases, the continental shelf.
The territorial sea baseline may be of various types depending upon the shape of the coastline in any given locality:
The Continental Shelf is the area of the seabed and subsoil which extends beyond the territorial sea to a distance of 200M from the territorial sea baseline and beyond that distance to the outer edge of the continental margin as defined in Article 76 of the Convention. The continental shelf is largely coextensive with the exclusive economic zone within 200M from the territorial sea baselines (there are certain areas between Australia and Indonesia and Australia and Papua New Guinea where they are not coextensive).
The national state electoral boundaries is a national coverage derived from the aggregation of the state and territories state electoral boundaries into a single coverage.
Coastal Waters is a belt of water between the limits of the Australian States and the Northern Territory and a line 3M seaward of the territorial sea baseline*. Jurisdiction over the water column and the subjacent seabed is vested in the adjacent State or Territory as if the area formed part of that State or Territory. This, and other arrangements for the management of offshore resources such as fisheries and petroleum, are defined by the Offshore Constitutional Settlement (OCS).
