Tree Cover Change in Victoria Between 1990 and 1995

Polygons showing tree cover change in Victoria between 1990 and 1995. The layer was derived from LANDSAT TM digital data, mapping woody vegetation greater than 2 metres in height and with crown cover greater than 10% down to a minimum area of quarter hectare. Attributes outlining causes of change are assigned for areas greater than 1 hectare.

Use Cases

• Analyze deforestation or afforestation trends based on mapped tree cover change polygons.
• Model environmental impacts based on attributed causes of change for areas over 1 hectare.
• Validate remote sensing algorithms based on LANDSAT TM-derived vegetation classifications.
• Assess land management policies based on quarter-hectare minimum mapping units.

Strengths

• Tree cover is mapped down to a minimum area of quarter hectare.
• Attributes outlining causes of tree cover change are assigned for areas greater than 1 hectare.
• Data is derived from LANDSAT TM digital data.
• Dataset has a specific temporal coverage of 1990-1995.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; the last metadata update is 2026-04-09.
