Applying SOM Cluster Analysis with Iterative Refinement to Infer Lithology Units in Eastern Victoria, Australia - Code (1.0)

The software (version 1.0.0) associated with the manuscript "Applying SOM Cluster Analysis with Iterative Refinement to Infer Lithology Units in Eastern Victoria, Australia" for the calculation and storage of PSDs is licensed under MIT and published on GitHub. MultiStepLithologyCluster is a geospatial data analysis tool that applies a modified Self-Organising Map (SOM) algorithm combined with an iterative multi-step clustering process to classify lithological units. It uses multi-modal geophysical survey data—including magnetic, radiometric, and gravity datasets with various signal enhancements—to improve geological interpretation and unit delineation, particularly in areas with limited surface exposure.
