Description
167 vector map tiles identify landscape areas attributed with geological names for bedrock geology at a 1:25,000 scale. The data is produced by the British Geological Survey (BGS) and covers selected 'classic' geological areas in Great Britain, such as Llandovery, Coniston, and the Cuillan Hills. It classifies rock types from igneous, metamorphic, and sedimentary classes, with ages ranging from the Archean eon to the Pliocene.
Use Cases
Map bedrock geology distribution based on polygon-identified landscape areas.
Analyze rock type composition based on classification into igneous, metamorphic, and sedimentary classes.
Study geological time periods based on rock ages attributed via the BGS lexicon.
Assess regional geological features based on coverage of 'classic' areas like the Lake District and Isle of Skye.
Strengths
Provides data at a detailed 1:25,000 scale.
Includes attribution for rock types based on the BGS Rock Classification Scheme.
Covers 167 distinct map tiles as of version 2.
Attributes rock ages spanning from the Archean eon to the Pliocene.
Limitations
Onshore coverage is partial and not intended to be nationally comprehensive.
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
