Victorian Soil Type Map with 3,300 Land Units and Reliability Index

Victoria, Australia, is covered by a harmonized soil type map based on the Australian Soil Classification. The dataset consists of 3,300 land units, totaling approximately 225,000 polygons, derived from around 100 surveys conducted over the past 70 years. It was developed by the Department of Energy, Environment and Climate Action, combining data from the Victorian Soil Information System and other sources, with a reliability index assigned to each unit.

Use Cases

• Regional land-use planning based on dominant soil type classifications.
• Environmental modeling and risk assessment based on soil order and suborder data.
• Agricultural suitability studies at a state-wide scale using the harmonized land unit map.
• Assessing data reliability for interpretation using the assigned qualitative reliability index.

Strengths

• Derived from approximately 100 soil and land surveys over 70 years, providing historical depth.
• Contains 3,300 attributed land units totaling about 225,000 polygons.
• Includes a qualitative reliability index for each land unit based on source survey quality.

Limitations

• Mapping is intended for regional overviews and may not be accurate for local or within-farm assessments.
• Land units are of variable scale and quality, and many contain multiple soil types.
• Column-level documentation is absent; field semantics must be inferred after download.
