The data are presented as a vector map of interlocking hexagon cells (side length 1 km, area c. 2.6 km2) covering the landmass of Great Britain as a regular grid. Each hexagon cell is attributed with statistics about the thickness of the underlying Quaternary units (average thickness and maximum thickness) for that cell. Additional information relating to the coverage of the underpinning data is also provided. The data are derived from the BGS Basic Superficial Thickness Model (BSTM). The data is all derived by spatially summarising the information within the BGS Basic Superficial Thickness Model (BSTM), which is a 50 m cell size raster model of superficial thickness, first published in 2010.

Details of how the original models were made can found in their downloadable user guide: User Guide for the British Geological Survey Superficial Deposit Thickness (1Km Hex-Grid) dataset. British Geological Survey Open Report OR/16/57: http://www.bgs.ac.uk/products/onshore/superficialThickness.html. To create this new dataset, the original BSTM (Basic Superficial Thickness Model) was spatially summarised by aggregating the original 50 m resolution raster data into vector hexagons (of area 2.6 km2). A typical hexagon cell contains the equivalent of just over 1000 raster cells (50 m x 50 m) from the original model. This means that each hexagon can extract its summary values from up to c. 1000 input cells. All spatial processing was performed in ESRI ArcGIS 10.3 using the zonal statistics tool within the Spatial Analyst extension. The data have been checked via standard BGS publication procedures.
