Soil Permeability Map for Sweden Based on Grain Size Classification

Lantmäteriet provides a simplified map of soil permeability across Sweden. The product reclassifies the JORDARTER 1:25 000 – 1:100 000 dataset into four permeability classes: low, medium, high, or unassessed. The classification is based solely on the grain size of the soil type in the foundation layer.

Use Cases

• Assessing initial risk of pollutant spreading from accidents based on simplified permeability classes.
• Planning site-specific environmental investigations based on a broad permeability overview.
• Integrating simplified soil permeability data into regional environmental models.

Strengths

• Based on the detailed JORDARTER 1:25 000 – 1:100 000 soil dataset.
• Provides a simplified four-class (low, medium, high, unassessed) classification for easier interpretation.
• Available as a WMS service for direct integration into mapping applications.

Limitations

• Permeability classification is based only on grain size and ignores factors like terrain location, saturation, and groundwater level.
• The product does not account for surface or underlying layers, which may affect actual permeability.
• Row count and last update date are unknown, limiting suitability assessment.
