High-Resolution LiDAR Terrain Models for Agricultural Plots in Québec

LiDAR-derived relief data covering crop plots in Québec enables detailed surface drainage modeling to identify erosion risks. The data includes numerical terrain models, shading, level curves, flow paths, and basins, integrated with declared agricultural plot boundaries. This dataset results from a collaboration between the MRNF and MAPAQ, aiming to support sustainable soil and water management interventions.

Use Cases

• Model surface drainage patterns to identify problem areas based on high-resolution relief data.
• Assess soil erosion risks within cultivated plots using flow path and basin information.
• Plan agricultural interventions by integrating terrain models with declared plot boundaries from the BDPPAD database.

Strengths

• Data is derived from high-resolution LiDAR surveys, suggesting detailed terrain capture.
• Includes multiple derived products like level curves, flow paths, and basins for analysis.
• Integrated with the declared agricultural plot database (BDPPAD) for contextual boundaries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is limited to crop plots and the territory of Québec, which may restrict broader applicability.
