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.
National State Boundaries is an aggregated dataset of the national coverage of all state boundaries from each state and territory.
This is a "place holder" container for national coverage of high-resolution imagery taken on a yearly basis or longer.
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.
National Regions is an aggregated dataset of the national coverage of all regional datasets for each state and territory.
National Boundary is a cartographic boundary for Australia.
Location, height and description of infrastructure, markers or other devices on land which may aid travellers in determining their position or safe course.
The National Flow Direction Grid is the national coverage of flow direction for all of Australia.
The Flow Direction Grid is a regular grid of surface flow directions accompanying the GEODATA 9 Second Digital Elevation Model (DEM) Version 3. It ascribes to each DEM point one of eight cardinal directions (E, SE, S, SW, W, NW, N, NE) denoting the direction of surface flow from each grid point to one of its eight immediate neighbours.
The NVIS framework was developed to enable the compilation of a nationally consistent vegetation dataset from data collected by states and territories. It provides a comprehensive means of describing and representing vegetation information based on establishing relationships between structural and floristic data. The NVIS Information Hierarchy is a system for describing the structural and floristic patterns of groups of plants in the landscape.
There are a number of geodetic observations and measurements performed at the national and local scale that contribute to datum definition, standards and lower positioning uncertainties. They also form part of the fundamental physical infrastructure that contribute to the National Positioning Infrastructure (NPI) Capability.
