Significant Geological Supplies Mapping For Perth Peel Region

2026-03-24 updated mapping identifies Basic Raw Material areas of state significance in Western Australia. The dataset, maintained by the Department of Energy, Mines, Industry Regulation and Safety, supports the State Planning Policy 2.4 framework. It includes designations for materials like Sand, with considerations for environmental values, land use, and infrastructure.

Use Cases

• Analyze spatial distribution of Significant Geological Supplies (SGS) areas designated as 'Sand' or other Basic Raw Material types for regional resource planning.
• Model land use conflicts by overlaying SGS areas with environmental values and current or future infrastructure layers.
• Assess BRM supply and demand considerations near growth areas and transport routes using the SGS area mapping.

Strengths

• Updated on 2026-03-24, indicating recent maintenance.
• Derived from an extensive interagency BRM planning process including public consultation in 2015.
• Supports multiple geospatial file formats including GeoJSON, SHP, and Geopackage for interoperability.

Limitations

• No quantitative data on resource size, scarcity, or demand is provided within the dataset.
• The mapping is specific to the Perth and Peel Region, limiting broader geographic applicability.
• Sample data and row/column counts are unavailable, obscuring dataset scale and structure.
