Northern Ireland Coastal Bedrock Geology Map

GSNI produced a coastal bedrock geology dataset for Northern Ireland, extending 200 meters inland and to a seaward depth of approximately 10 meters. The dataset was created by refining the 1:10,000 digital bedrock geology map, incorporating unpublished data to fill gaps and account for significant coastal change. It aligns with the spatial extent of the Northern Ireland 3-Dimensional Coastal Survey.

Use Cases

• Coastal erosion modeling based on bedrock type and coastal change data.
• Marine spatial planning using the seaward geological extent.
• Geological hazard assessment for the coastal zone.
• Integrating geological data with 3D coastal survey models.

Strengths

• Derived from the authoritative 1:10,000 scale digital bedrock geology map.
• Refined to account for significant coastal changes since the original survey.
• Cross-platform presence on UK and EU open data portals indicates official importance.

Limitations

• Column names and data structure are unknown, limiting detailed understanding.
• No row count or file size information is provided.
• One source lists a future 'last updated' date (2026-04 15), which is a conflict or error.
