British Geological Survey and Natural Resources Wales jointly classify geologic units in Wales into Principal Aquifers, Secondary Aquifers, and Unproductive Strata. The dataset supports groundwater protection policies consistent with the Water Framework Directive. It is derived from the BGS Geology 50k (DiGMapGB-50) mapping.
Use Cases
- Model groundwater vulnerability based on aquifer designation categories.
- Assess drinking water supply potential based on Principal Aquifer classifications.
- Analyze ecosystem support by mapping aquifer roles in surface water flows and wetlands.
- Inform land-use planning and environmental policy based on geologic unit designations.
Strengths
- Jointly owned by authoritative bodies British Geological Survey and Natural Resources Wales.
- Classifications align with the Water Framework Directive for policy consistency.
- Derived from the detailed BGS Geology 50k (DiGMapGB-50) base mapping.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to its focus on Wales.
