Forest Cover Change in Southern Quebec Detected by Sentinel-2 Satellite

Southern Quebec forest cover changes are tracked in this provincial vector database produced by automated analysis of Sentinel-2 satellite imagery. It contains disturbances of anthropogenic or natural origin, detected at a 10 m × 10 m resolution, and excludes changes already documented in official databases for harvesting, fires, and other events. The analysis is performed annually by the Government and Municipalities of Québec using imagery from June to September.

Use Cases

• Monitor unregistered deforestation based on automated satellite detection.
• Track natural forest disturbances like storms or pests where official records are lacking.
• Validate or supplement official forestry and wildfire databases with independent satellite observations.
• Analyze annual trends in forest cover change across southern Quebec.

Strengths

• Provides 10 m × 10 m resolution data from Sentinel-2 imagery.
• Focuses on disturbances not yet recorded in official databases, filling an information gap.
• Updated annually with a defined analysis period (October-November using June-September imagery).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to open_canada, focusing only on southern Quebec.
