Annual Woody Vegetation Change Classifications 1972-1977

Annual products identify changes in perennial woody vegetation between forest, sparse woody, and non-woody classifications. The data, created by Landgate, covers the period from 1972 to 1977.

Use Cases

• Analyze trends in forest-to-non-woody change classes to quantify deforestation rates over the 1972-1977 period.
• Map transitions from non-woody to sparse woody classifications to study vegetation regrowth patterns.
• Use the no-change, sparse-to-non-woody, and forest-to-sparse change classes to model landscape stability and degradation.

Strengths

• Annual time series provides consistent year-over-year change detection.
• Change products differentiate between six specific transition classes.

Limitations

• Data is derived from 30m resolution Landsat imagery, limiting detail for small-scale changes.
• Temporal coverage is limited to a specific five-year historical period (1972-1977).
