Upper Lough Erne Network Contribution: Hydrological Connectivity Scores

Network contribution area scores for Upper Lough Erne, derived from 2007 land cover, average rainfall, and a 5-meter digital terrain model. The scores, exported from the SciMAP application within SAGA GIS, identify high-contribution areas defined as one standard deviation above the mean. This geospatial layer supports hydrological analysis and water resource management for the Northern Ireland region.

Use Cases

• Identifying high-contribution zones for surface water flow based on land cover and rainfall inputs.
• Visualizing hydrological network connectivity in web maps and dashboards for environmental monitoring.
• Supporting catchment area analysis and flood risk assessment using derived contribution scores.
• Integrating with other geospatial layers for landscape-scale environmental planning.

Strengths

• Derived from specific, documented input sources: CEH Land Cover 2007, Met Office average rainfall, and a 5-meter DTM.
• Available under the permissive OGL-UK-3.0 license, facilitating reuse and distribution.
• Cross-platform presence on uk_data and eu_open_data indicates established utility and accessibility.

Limitations

• Core input data (land cover) is from 2007, which may not reflect current land use conditions.
• Column names and dataset structure (e.g., row count, file size) are not documented in any source.
• The 'last updated' metadata shows a future date (2026-07-08), indicating potential timestamp inaccuracies.

Collection Method

Scores were exported from SciMAP application outputs within SAGA GIS, based on CEH Land Cover 2007, Met Office average rainfall, and a 5-meter DTM.

Time Range

2007 (based on land cover input)

Freshness

Last updated metadata points to 2026-07-08, but this is a future date and likely erroneous; the underlying data is based on inputs from 2007.
