Western Australia Oil Mallee Belt Plantation Density Grid

A 2026 dataset from DPIRD Geographic Information Services maps oil mallee belt plantations across Western Australia using a 20,000-hectare grid system. It contains attributed grid squares showing total plantation area and ground-truthing status, derived from orthophotography digitization and field verification.

Use Cases

• Analyze Total_Area per grid to model spatial distribution and density of oil mallee belt plantings.
• Assess data reliability by filtering grids based on the Ground_Truthed attribute.
• Use the 200 km² grid geometry for regional biomass or carbon sequestration estimates.
• Validate remote sensing classification algorithms using the ground-truthed plantation extents.

Strengths

• Grid system uses a standardized 200 km² (20,000 ha) cell size for consistent spatial analysis.
• Includes a Ground_Truthed attribute indicating field-verified data quality for certain areas.
• Derived from the authoritative DPIRD land use areas of interest database.

Limitations

• Limited to belt plantings only, excluding block-planted mallee areas.
• Field verification was conducted only in a small region of the state, limiting statewide validation.
• Dataset size, row count, and specific column details beyond the two mentioned are unknown.
