Landform Component Polygons for North West Victoria, Derived from DEM Analysis

A polygonal dataset of mapped landforms in the Victorian Mallee region, disaggregated from historical land systems. The dataset was created by the Department of Energy, Environment and Climate Action using a 10-metre grid Digital Elevation Model, derivative surfaces, and expert opinion, with funding from the Caring for our Country initiative. It was supplemented during a 2011 wind erosion project and was last updated on 2026-04 09.

Use Cases

• Modeling wind erosion susceptibility based on refined landform components from the 2011 project.
• Analyzing terrain characteristics for ecological studies using DEM derivative surfaces like slope and curvature.
• Integrating landform data with supplementary datasets such as aerial imagery and radiometrics for environmental planning.

Strengths

• Created using a high-resolution 10-metre grid Digital Elevation Model (DEM).
• Analysis incorporated multiple indices and derivative surfaces, including UPNESS, MrVBF, slope, and curvature.
• Dataset refinement is documented in a specific 2011 project report on wind erosion susceptibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect geographic bias inherent to the specific Mallee region of Victoria.
