Wheatbelt Cropping Boundary of Western Australia

A geographic boundary dataset defining the limit of wheat cropping in Western Australia, created by DPIRD Geographic Information Services in August 2009. The dataset was updated in June 2012 to incorporate a 2011 recapture of the eastern clearing line.

Use Cases

• Delineate the eastern cropping limit using the updated Clearing Line feature for land-use policy analysis.
• Analyze changes in the Wheatbelt boundary between the 2002 and 2011 recapture periods for agricultural monitoring.
• Integrate the boundary with other spatial data using the provided WFS, WMS, or SHP file formats for regional planning.

Strengths

• Boundary defined using interpretation of the best available aerial photography for the western/southern limit.
• Eastern limit defined by the official Clearing Line, recaptured in 2011 for the June 2012 update.
• Maintained by the authoritative Department of Primary Industries and Regional Development (DPIRD).

Limitations

• No tabular column or row count information is provided for quantitative analysis.
• The core boundary definition is over a decade old, though the dataset metadata was updated in 2026.
