Representative data and code supporting Chapter 2 of Jianguo Liu's PhD thesis: Time-lapse ERT processing workflow at Gnangara

This repository provides a representative example of the Electrical Resistivity Tomography (ERT) processing workflow used for the Gnangara (GN) monitoring site in Western Australia. A selected set of 28 surveys from 26 June to 23 July 2023 is included to demonstrate the main processing stages, rather than to provide the complete Gnangara time-series dataset.

The archive contains raw 4Point Light ERT files, BERT inversion input files, BERT inversion outputs, soil-temperature records, temperature-corrected resistivity models, reconstructed electrode contact-resistance data, and the Python scripts used for the contact-resistance calculation. Files retain consistent timestamp-based names across the processing folders, allowing individual ERT surveys to be followed from raw acquisition through inversion and temperature correction. The raw .tx0 files also provide the input data used for contact-resistance reconstruction.

This repository primarily supports the methodology presented in Chapter 2 of Jianguo Liu’s PhD thesis. It is intended to document the data-processing workflow, provide representative examples of the file formats used at different processing stages, and improve the transparency and reproducibility of the methods described in the thesis. The included Gnangara surveys should therefore be interpreted as representative examples of the methodology rather than as a complete research dataset.
