Elevation of the Pre-Tertiary Basement in the Murray Basin

Structure contours in meters AHD of the pre-Tertiary basement across the Murray Basin. The dataset is an appended set from the 1:250,000 scale Murray Basin Hydrogeological Map Series, originally published by the Australian Geological Survey Organisation. It was issued under the authority of the Minister for Primary Industry and Energy and is jointly produced by Commonwealth, New South Wales, Victorian, and South Australian governments.

Use Cases

• Hydrogeological mapping for land and water management based on structure contours.
• Modeling groundwater flow and salinisation risk based on basement elevation data.
• Regional geological analysis and basin structure studies based on the pre-Tertiary basement surface.

Strengths

• Data is part of a formal 1:250,000 scale map series produced by government geological surveys.
• Dataset is a multi-government collaborative effort involving Commonwealth, NSW, Victorian, and South Australian authorities.
• Explicitly intended for hydrogeological mapping for land and water management.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The source agency notes it does not guarantee the information is totally accurate or complete.
