AEMInterpConvert: Australian Airborne Electromagnetic Interpretation Data

Over 115,000 flight line kilometers of airborne electromagnetic (AEM) data, covering 2,085,000 km² or 27% of the Australian continent, have been processed using this conversion workflow. Geoscience Australia developed the AEMInterpConvert tool to facilitate the digitization, attribution, and format conversion of AEM interpretation linework. The tool produces outputs designed to support 3D geological modelling for cover thickness and basement depth investigations.

Use Cases

• Estimate cover thicknesses and depths to basement for 3D geological modelling based on the described interpretation workflow.
• Generate interpretation aids and validate spatial, geometric, and attribute data for airborne electromagnetic surveys.
• Convert AEM interpretation linework into various software-compatible formats for use in decision-making and hazard mapping.
• Support land use and environmental management planning with interpreted subsurface geological data.

Strengths

• Covers over 115,000 flight line kilometers of airborne electromagnetic data.
• Encompasses a survey area of 2,085,000 km², representing 27% of the Australian continent.
• Workflow prioritizes accessibility by utilizing widely-used Geographic Information Systems and open-source software.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
