Latrobe Valley 3D Coal Model Boundary, 4912 km2 Coverage

9086 cores have been modelled over a total area of 4912 km2, defining the extent of the 2011 version of the Digital 3D Geological Model of the Latrobe Valley Coal Resource. The model, based on pre-mine topography, integrates a century of coal delineation work and is published by the Department of Energy, Environment and Climate Action on data_gov_au. It was last updated on 2026-04-09.

Use Cases

• Regional-scale resource management based on the 3D geological model of coal seams.
• Matching coal deposits to development opportunities based on the modelled seam extents.
• Informing land use planning based on the polygon boundary and underlying geological data.
• Analyzing coal seam extensions into the Seaspray Depression and Moe Swamp based on the model's coverage.

Strengths

• Covers 4912 km2, including all Gippsland brown coal fields identified in the inventory.
• Models 9086 cores, an increase of 641 bores over the 2008 version.
• Integrates a century of coal delineation work into a contemporary 3D format.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Based on a pre-mine topography, and substantial coal has already been extracted, which may affect current applicability.
