Full description

In recent years, Geoscience Australia, along with the state and territory geological surveys, have collected and processed vast amounts of airborne electromagnetic (AEM) data. With the acquisition of the AusAEM survey (Ley-Cooper et al., 2020) and the intention to collect large amounts of interpretation-specific metadata for the Estimates of Geological and Geophysical Surfaces database (EGGS; Mathews et al., 2020), an assessment was made on the available software capable of efficiently creating the intended interpretations.

Shortcomings in existing applications prompted the development of a new interpretation workflow: the Multilayered chronostratigraphic airborne electromagnetic interpretation workflow (Wong et al., 2022). This workflow facilitates digitising the interpretation linework and attributing these lines with a wide range of interpretation-specific data. Development of this workflow prioritised accessibility by utilising widely-used Geographic Information Systems and open-source software. The conversion component can provide the interpretation outputs in a range of formats compatible with most applicable software packages. This conversion process also includes the production of interpretation aids prior to interpretation and to validate spatial, geometric and attribute data, post interpretation.

The conversion component in this workflow was initially scripted in the AWK programming language, which is currently used in Geoscience Australia’s production Multilayered chronostratigraphic AEM interpretation workflow (Wong et al., 2022). This conversion process has been used to convert AEM interpretation from over 115,000 flight line km, covering mostly 20 km-spaced flight lines over an area of 2,085,000 km2 or 27% of the Australian continent (Connors et al., 2022; Folkes et al., 2022; Vilhena et al. 2023; Wong et al., 2020; Wong et al., 2021; Wong et al., 2023).

The AEMInterpConvert tool has been developed to improve accessibility and user-friendliness of the interpretation conversion component of the workflow. This tool allows users to produce the interpretation aids, run the validations and export interpretation in various formats without the need for any specialised software or programming experience.

This document provides a metadata statement and user guide for the AEMInterpConvert’s online graphical user interface. Outputs from this tool are designed to support investigations of cover thicknesses and depths to basements for 3D geological modelling. These interpretations and models are in turn used to inform academia, industry and government on decision-making, land use, environmental management, hazard mapping and resource exploration.

Statement:
The AEMInterpConvert tool is based on the airborne electromagnetic interpretation conversion process that was developed as part of the Exploring for the Future Program and was published in the multilayered chronostratigraphic airborne electromagnetic interpretation workflow Geoscience Australia record https://pid.geoscience.gov.au/dataset/ga/147251 (Wong et al., 2022). The original conversion process was scripted by Malcolm Nicoll in the AWK programming language and was used to convert AEM interpretations created as part of the Exploring for the Future Program. This workflow shares some similarities to previous work at Geoscience Australia, involving the capture of section-based interpretation with commonly available geographic information systems (GIS) software and existing skillsets. This technique has been applied to deep seismic reflection interpretation, magnetotelluric interpretation, geological cross sections and 2D models for forward modelling. This online graphical user interface version of the workflow is aimed at adding additional functionality and user-friendliness to the conversion process.

Notes

Purpose
This document is to be used as a metadata statement and user guide for the Layered Chronostratigraphic Airborne Electromagnetic Interpretation Online Conversion Workflow. The workflow itself is used to convert airborne electromagnetic interpretations made in geographic information systems to 2D, 3D and comma delimited formats. The tool is also used for a range of spatial, geometric and attribute validations.
