Siigsol-100m: Soil Properties Map of Southern Québec at 100m Resolution

SiIGsol-100m maps document the spatial evolution of six key soil properties across non-urbanized land in southern Québec. These 100-meter resolution values were simulated by combining point observations with remote-sensing covariates using automated learning methods. The data, provided by the Government and Municipalities of Québec, is available in six depth layers and was last updated in April 2026.

Use Cases

• Predict agricultural suitability based on simulated soil texture (sand, silt, clay fractions) and pH.
• Model carbon storage potential using the simulated proportion of organic matter across depth layers.
• Assess soil fertility and nutrient retention capacity using the simulated cation exchange capacity.
• Analyze spatial trends in soil properties for environmental monitoring and conservation planning.

Strengths

• Covers the entire territory of the Province of Québec located south of the 55th parallel.
• Provides data for six variables (sand, silt, clay, pH, cation exchange capacity, organic matter) across six standardized depth layers.
• Uses a combination of point observation data and spatially explicit covariates from remote sensing.
• Available under a permissive CC-BY-4.0 license.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Values are simulated predictions, not direct observations, as noted in the description.
