Acid Sulphate Soil Distribution Model for Coastal Sweden

Lantmäteriet's 'Acid sulphate soil' display service combines a surface-covering model with point observations to show the likely distribution of acid sulphate soils along the coasts of Västernorrland, Västerbotten, and Norrbotten. The model classifies areas as 'Non-acid sulphate soil', 'Active acid sulphate soil on potential acid sulphate soil', and 'Potential acid sulphate soil'. The data is provided via a WMS service under a CC0-1.0 license.

Use Cases

• Identify areas for risk avoidance based on the modelled distribution of acid sulphate soils.
• Plan mitigation measures based on the classification of 'Active' and 'Potential' acid sulphate soils.
• Support environmental impact assessments using the combined surface model and point observation data.

Strengths

• Includes both a modelled surface layer and collected point observations for validation.
• Provides a specific classification system for different soil risk states.
• Focuses on a defined geographic region (coastal counties of Sweden).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
