GcBÜK400: Geochemical Soil Survey Maps of Saxony at 1:400,000 Scale

Geochemical overview maps present inorganic material data from soils in Saxony as interpolated raster data at a 1:400,000 scale. Depending on the element, analyses from between 13,000 and 19,000 locations were used to map the upper soil layers. The data originates from multiple measurement programs aggregated by the Saxon State Office for Environment, Agriculture and Geology.

Use Cases

• Map regional soil contamination based on inorganic element concentrations mentioned in the description
• Analyze geochemical baselines for soil health based on interpolated raster data from thousands of sampling points
• Conduct environmental risk assessments based on the statistical classification of soil element data

Strengths

• Data is derived from a large sample size of between 13,000 and 19,000 locations per element
• Maps are produced at a standardized regional scale of 1:400,000
• The legend classification is statistically derived from the data collectives

Limitations

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