Superficial Deposit Thickness dataset (1km 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 1km, area c.2.6 Km2) covering the landmass of Great Britain as a regular grid. Each hexagon cell is attributed with a series of statistics about the thickness of the underlying Quaternary units (e.g. average); additional information relating to the thickness models and the coverage of underpinning data is provided. The data is all derived by spatially summarising the information originally created for the high-resolution Superficial Deposit Thickness Model (a 50m cell size raster model of thickness, first published in 2010).

Statement: The data in the SDTM (1Km hex-grid) dataset has been generalised (using spatial statistics) from the original, high resolution BGS Superficial Deposit Thickness Models (first published in 2010). Details of how the original models were made can found in their downloadable user guide here: (http://www.bgs.ac.uk/products/onshore/superficialThickness.html). To make this new dataset, the original BSTM (Basic Superficial Thickness Model) have been spatially summarised by aggregating the original, 50m resolution raster, data into vector hexagons of 2.6 km2 area. A typical 2.6 Km2 hexagon cell contains the equivalent of just over one thousand raster cells (each is 50m by 50m) 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 ESRIs ARCGIS10.3 using the zonal statistics tool within the Spatial analyst extension. The data has been checked via the standard BGS publication procedures.
