Annual Woody Vegetation Change Maps for Western Australia 1995-1998

Landgate's annual vegetation change products track transitions in perennial woody cover between forest, sparse woody, and non-woody classes. The dataset identifies locations of change using Landsat imagery at a 30-meter resolution for the period 1995 to 1998. Change classes include no change, non-woody to sparse, non-woody to forest, sparse to non-woody, forest to non-woody, and forest to sparse.

Use Cases

• Analyze trends in forest to non-woody and forest to sparse change classes to quantify deforestation or degradation.
• Model transitions from non-woody to sparse woody vegetation to study land recovery or afforestation patterns.
• Map annual changes in perennial woody vegetation cover using the 30-meter Landsat pixel classification.
• Assess regional stability by identifying areas with a persistent no change classification over the multi-year period.

Strengths

• Provides annual change detection for a four-year period (1995-1998).
• Uses Landsat imagery with a consistent 30-meter ground pixel resolution.
• Distinguishes six specific change classes, including bidirectional transitions between three cover types.

Limitations

• Temporal coverage is limited to a specific historical window (1995-1998).
• Spatial resolution of 30 meters may not capture fine-scale vegetation changes.
• Data format includes DOCX and WMS, which may require specialized GIS tools for full analysis.
