Annual Woody Vegetation Change Classification For Western Australia

Landgate's Woody Change product identifies annual changes in perennial woody vegetation from Landsat imagery. It classifies transitions between forest, sparse woody, and non-woody categories for the 2011-2012 period. The dataset includes change classes such as non-woody to forest and forest to non-woody.

Use Cases

• Analyze the spatial distribution of the 'forest to non-woody' change class to identify deforestation hotspots.
• Model temporal trends in the 'non-woody to sparse' transition class to assess land recovery.
• Validate regional vegetation models by comparing predicted and observed 'sparse to non-woody' classifications.
• Assess the stability of woody cover by quantifying areas of 'no change' across the monitoring period.

Strengths

• Derived from Landsat imagery providing 30-meter ground pixel resolution.
• Produced by Landgate, the authoritative land information agency for Western Australia.
• Includes six specific change classes for detailed transition analysis.

Limitations

• Specific row count, column count, and dataset size are unknown.
• Temporal coverage is limited to a single annual period (2011-2012).
• Data format includes DOCX and WMS, which may require specialized GIS tools for full analysis.
