BGS Superficial Deposits Thickness Model 1 km hex grid

This dataset shows the variation of the thickness of superficial (Quaternary age) deposits across Great Britain. 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.
