Superficial Deposits Thickness Model for Great Britain on a 1 km Hex Grid

A vector map of Great Britain using interlocking 1 km hexagon cells, each attributed with statistics on the thickness of Quaternary-age superficial deposits. The data are derived by spatially summarizing the British Geological Survey's 50 m cell size Basic Superficial Thickness Model, first published in 2010. It provides average and maximum thickness values per cell, along with coverage information for the underpinning data.

Use Cases

• Modeling geological hazard susceptibility based on superficial deposit thickness.
• Planning site investigations for construction by identifying areas with potentially thick, unconsolidated material.
• Analyzing spatial patterns of Quaternary sediment distribution across Great Britain.
• Integrating subsurface data into environmental or hydrological models.

Strengths

• Data derived from the authoritative British Geological Survey (BGS) Basic Superficial Thickness Model.
• Provides two key thickness statistics per cell: average and maximum.
• Covers the entire landmass of Great Britain as a regular grid of approximately 2.6 km² hexagons.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The underlying raster model was first published in 2010; local conditions may have changed.
