Digital datasets from the Great Artesian Basin Atlas
The Great Artesian Basin (GAB) is one of Australia's most significant hydrogeological entities covering more than 1.7 million square kilometres, underlying parts of Queensland, New South Wales, South Australia and the Northern Territory. The GAB contains a vast volume of underground water (estimated at 64,900 million megalitres) and is the largest groundwater basin in Australia. Groundwater resources in the GAB are used to support the pastoral, agricultural, and resource sectors as well as supplying water to inland communities. Properly managing these groundwater resources, often for competing interests, requires an understanding of how the groundwater system works at a regional scale.
The Hydrogeological Atlas of the Great Artesian Basin presents a compilation of maps documenting some of the key regional geological, hydrogeological and hydrochemical aspects of the GAB. It provides insights into the current understanding of the regional geometry and physical characteristics of the rocks and water contained within this vast groundwater basin and baseline information against which future changes can be assessed.
The digital datasets from the GAB Atlas are the shapefiles from which the atlas was produced. These can be subsetted, manipulated, combined with external datasets, or recombined in interesting ways.
