Surface Deposit Maps For Southern Quebec At 1:50,000 Scale

Surface deposit maps categorize the loose material covering bedrock across Quebec south of the 52nd parallel. The data is derived from aerial photograph interpretation at a 1:40,000 scale and field control points, supporting ecological forest product development. Maps are distributed by 1:50,000 scale map sheets with a minimum mapping unit of 4 hectares.

Use Cases

• Classify surface deposit categories using interpreted aerial photography and field indicators for ecological modeling.
• Analyze the distribution and thickness of surface deposits across Quebec's southern territory for landform studies.
• Map the relationship between deposit type and slope position or soil texture as part of regional ecoforest inventories.

Strengths

• Covers almost the entire territory of Quebec south of the 52nd parallel.
• Derived from aerial photograph interpretation at a detailed scale of 1:40,000.
• Features a minimum mapping unit of 4 hectares for surface deposit polygons.
• Distributed in standardized 1:50,000 scale map sheets for consistent use.

Limitations

• Column names and sample data are unavailable, limiting understanding of the data structure.
• The original metadata was translated via an automated tool, which may introduce inaccuracies.
• Data format includes PDF and HTML, which are less machine-actionable for analysis than structured formats.
