Terrestrial LiDAR Data of Lithalsas in Tasiapik Valley, Nunavik

Terrestrial LiDAR data covers a lithalsas field in the Tasiapik Valley near Umiujaq, Nunavik, Québec. It was produced as part of a Master's research project at Université Laval to study thaw subsidence of ice-rich permafrost. The dataset was authored by Madeleine St-Cyr and last updated on June 20, 2026.

Use Cases

• Modeling thaw subsidence rates based on high-resolution terrain data
• Analyzing the morphology and stability of lithalsas based on LiDAR-derived elevation
• Monitoring changes in ice-rich permafrost landscapes over time

Strengths

• Data is focused on a specific, well-defined geomorphological feature (lithalsas field)
• Produced as part of academic research at Université Laval, suggesting a scientific methodology

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
