Quebec Ecoforest Maps at 1:10,000 Scale from 2025

Since 2025, ecoforest maps for Quebec up to the 52nd parallel have been produced at a 1:10,000 scale, with each sheet covering approximately 62.5 km² and offering ±5 m accuracy. These maps are created by the Government of Quebec through photo-interpretation of aerial photographs, integrating natural disturbances and forest interventions. They provide detailed vegetation information by species or species groups, based on the most recent forest inventories.

Use Cases

• Analyze vegetation characterization by detailed species (AIPF) or species groups to model forest composition changes over time.
• Map natural disturbances like fires and epidemics, combined with forest interventions such as harvesting, to assess ecological impacts.
• Use georeferenced 1:10,000 scale maps with ±5 m accuracy for high-resolution spatial analysis of forest stands.
• Compare forest codes and inventory methodologies across map years (e.g., 2015 vs. 2025) to track classification system evolution.

Strengths

• High spatial accuracy of ±5 meters for maps produced at the 1:10,000 scale since 2025.
• Each 1:10,000 scale map covers a defined area of approximately 62.5 square kilometers.
• Integrates multiple data sources, including aerial photo-interpretation, disturbance tracking, and inventory updates.
• Provides temporal coverage from at least 2015 to 2025, showing methodology evolution.

Limitations

• Vegetation detail varies; some sheets provide species-level (AIPF) data while others only offer species groups.
• Forest code legends are not standardized and change between inventory years, requiring careful consultation.
• Data is provided in multiple formats (PDF, GeoJSON, etc.) which may require consolidation for analysis.
