DiGMapGB-25 Artificial: Map of Human-Modified Ground in Great Britain

Digital Geological Map Data of Great Britain - 25k (DiGMapGB-25) Artificial version 2 identifies 167 10x10km tiles of landscape areas where the ground surface has been significantly modified by human activity. The data, provided by the British Geological Survey (BGS), includes polygons attributed with types of artificial ground such as disturbed, infilled, made, and worked ground. This version 2 release added tiles in 2012, but the data represents a snapshot in time and may become dated rapidly.

Use Cases

• Assessing land stability for construction based on mapped areas of infilled ground like landfill sites.
• Planning mineral resource management based on identified areas of disturbed or worked ground from shallow workings.
• Modeling hydrological impacts based on the location of man-made features like embankments and spoil heaps.
• Evaluating historical land use change based on the snapshot of artificial ground modification.

Strengths

• Data exists for 167 10x10km tiles, providing specific spatial coverage.
• Includes detailed classification of artificial ground types (disturbed, infilled, made, worked).
• Primary geological mapping was carried out at a detailed 1:10,000 scale in many areas.

Limitations

• Coverage is described as 'limited within Great Britain'.
• The data is a snapshot and may become dated rapidly due to shifting land use.
• Column-level documentation is absent; field semantics must be inferred after download.
