Geomorphology of Victoria: A Hierarchical Landform Framework at Three Scales

A hierarchical framework of geomorphological spatial entities at three tiers, with Tier 1 containing 8 Divisions, Tier 2 containing 34 categories, and Tier 3 containing 95 categories. The dataset, created by the Department of Energy, Environment and Climate Action, provides a spatial system to assist planning, monitoring and reporting for natural resource management in Victoria and Australia. It was last updated on 2026-04-08.

Use Cases

• Landscape planning and monitoring based on the hierarchical Victorian Geomorphology Framework (VGF).
• Soil erosion susceptibility assessment based on the GMU250 layer and underlying soil information.
• Aligning past and future soil and land information based on the provided hierarchical land type system.
• Regional-scale environmental reporting based on the multi-tiered spatial framework.

Strengths

• Provides a structured hierarchy with 8 Tier 1 Divisions, 34 Tier 2 categories, and 95 Tier 3 categories.
• Includes soil erosion susceptibility assessments derived from regional studies at scales of 1:100,000 or finer.
• Available under a permissive CC-BY-4.0 license for reuse.

Limitations

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