Datasets

National Groundwater

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 Flow Direction Grid

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.

National Vegetation Information System

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.
