Northern Ireland Coastal Bedrock Geology Map

GSNI's coastal dataset details bedrock geology along the entire Northern Ireland coast, extending 200 meters inland and to a seaward depth of approximately 10 meters. It refines the 1:10,000 digital bedrock map, incorporating unpublished data to address gaps and significant coastal changes. This dataset aligns with the Northern Ireland 3-Dimensional Coastal Survey, providing a specialized geological layer for coastal analysis.

Use Cases

• Coastal erosion modeling based on bedrock type and structure
• Marine habitat mapping linked to underlying geological formations
• Infrastructure planning for coastal developments using bedrock stability data
• Refining regional geological maps with updated coastal change observations

Strengths

• Derived from the detailed 1:10,000 scale digital bedrock geology map
• Spatial coverage is comprehensive for the entire Northern Ireland coastline
• Integrates unpublished datasets to fill gaps in the original survey

Limitations

• Column names and data structure are not specified in any source
• Dataset size and row count are unknown, limiting assessment of granularity
• One source lists a last updated date of 2026-04-15, which is a future date and may be an error
