Western Australia Woody Vegetation Cover Since 1988

Landgate's Vegetation Cover dataset provides annual state-wide maps of perennial woody vegetation derived from 30-meter resolution Landsat imagery. It classifies vegetation into two structural categories based on cover density and height, with data available from 1988 onward.

Use Cases

• Analyze long-term trends in forest category cover density using annual imagery from 1988.
• Model spatial distribution of sparse woody vegetation category across Western Australia.
• Monitor changes in perennial woody vegetation structure meeting 2m height and 20% cover thresholds.

Strengths

• Annual time series provides over 30 years of data starting from 1988.
• State-wide spatial coverage for Western Australia.
• Classification based on two specific structural criteria: cover density and height at maturity.

Limitations

• Limited to two vegetation classes, lacking finer species or health detail.
• Spatial resolution is 30 meters, which may miss smaller vegetation features.
• Primary data formats are web services (WMS, ArcGIS), not direct tabular files.
