National scale maps of parent material properties, terrain and soil natural capital units at 50 metre resolution for Great Britain, 2020

This dataset contains national scale maps on several characteristics of soils and landscapes across Great Britain, circa 2020. Key soil parent material categories featured here include texture, drainage, depth, organic matter and calcium carbonate contents. Terrain information includes landform classes, topographic wetness index, and indices of valley bottom flatness and ridge top flatness. Our maps were derived from components of the BGS's Depth to Groundwater and Parent Material Models, digita

Useful for

Use cases llm-inferred
Catchment-scale soil drainage and parent material screening for flood risk or SuDS feasibility · Soil natural capital baseline for ecological or land-use assessments at whole-field to national scale · Topographic wetness index and landform inputs for hydrological screening across river catchments
Audience llm-inferred

Limitations

Constraints docs-verified
Non-Commercial Government Licence restricts commercial use; confirm licence position before using in paid consultancy deliverables · 1 km smoothing blurs detail; not suitable for sub-field scales (docs advise whole-field or larger domains) · Northern Ireland excluded from the dataset · Agreement with reference maps: 63% (drainage vs HOST), 53% (texture), 72% (physico-chemical) · Snapshot representative of 2020; texture, depth, calcium carbonate and drainage reflect longer-term conditions
