The DiGMap Plus dataset is a series of GIS layers describing the engineering properties of materials from the base of pedological soil down to c. 3m depth (ie the uppermost c.2m of geology). These deposits display a variable degree of weathering, but still exhibit core engineering characteristics relating to their lithologies. The 'Strength' dataset covers England, Scotland and Wales and characterises the material lithology, and its strength (for field description purposes) as outlined in documentation relating to BS5930 (1999 and 2003 and Eurocode7).

Text files of physical parameters controlled or measured in rock heating and deformation experiments; jpg and tif files of optical and electron microscope images of experimental products; xome xlsx spreadsheets related to data interpretation.
