Onion Suitability Model for Southern Grampians Shire

Southern Grampians Shire Council provides a geospatial model assessing land suitability for onion cultivation. The model was developed by Deakin University as part of a Land Use Capability project. The dataset was last updated in April 2026.

Use Cases

• Identify high-suitability zones for onion farming using modelled land capability scores.
• Compare soil and terrain constraints across the shire for agricultural planning.
• Integrate modelled suitability polygons with other land-use or soil data layers.
• Validate the model's predictions against actual crop yield data from local farms.

Strengths

• Model developed by Deakin University with a linked scientific report detailing methods.
• Data is provided in multiple geospatial formats (GEOJSON, CSV, SHP, WMS, WFS) for flexibility.

Limitations

• The dataset scope is limited to a single commodity (onion) and a single local government area.
• The underlying model's accuracy is dependent on the input data and assumptions described in the report, which may be outdated.
