Digital Surface Model for Land Management Applications

A 2026 dataset from the Government of Québec provides digital surface models representing Earth's surface with permanent landscape elements. These models are essential for land management applications, distinguishing between bare ground and surface features like buildings. The data is available in GEOTIF, HTML, and PDF formats.

Use Cases

• Analyze surface relief for land management applications using the digital surface model (MNS).
• Integrate the MNS with a Numerical Canopy Model to create a complete landscape representation including vegetation.
• Distinguish between bare ground altitude and surface features like buildings for infrastructure planning.

Strengths

• Data is current, with a last update in March 2026.
• Provides a specialized representation of surface altitude, distinct from bare ground models.
• Produced by the authoritative Government and Municipalities of Québec.

Limitations

• Specific technical details like spatial resolution, coverage area, and data volume are unknown.
• Sample data is unavailable for preview, hindering initial assessment of data structure and quality.
• The original description was machine-translated, which may introduce inaccuracies in metadata.
