Northern Quebec Surface Deposit Map 2010-2013

2010-2013 mapping of surface deposits across northern Quebec, an area of approximately 680,000 km2. The inventory was created using RapidEye satellite imagery with 5-meter spatial resolution and validated with ground and air control points. It distinguishes main deposit categories, their nature, thickness, and distribution.

Use Cases

• Classify surface deposit categories using the mapped nature and distribution data for geological studies.
• Analyze deposit thickness and texture of the soil indicators for terrain stability assessments.
• Model the relationship between land shape, slope position, and deposit type using the interpreted geomorphological data.

Strengths

• Covers an extensive area of approximately 680,000 km2 north of the 53rd parallel.
• Created using high spatial resolution (5 m) RapidEye anaglyph satellite imagery.
• Interpretation and validation performed by geomorphologists with ground and air control points.

Limitations

• Data is from a 2010-2013 inventory and may not reflect recent changes.
• Minimum mapping area of 100 hectares limits detail for smaller features.
