Owenkillew Network Contribution: Hydrological Connectivity Scores

Owenkillew Network Contribution scores quantify areas of high hydrological connectivity in Northern Ireland. The scores were generated in SAGA GIS using inputs from CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model. This geospatial layer is suitable for web map visualization, dashboard analysis, and download in multiple formats.

Use Cases

• Identifying high-contribution zones for surface water flow based on a standard deviation threshold.
• Visualizing hydrological network connectivity for web-based environmental dashboards.
• Integrating land cover and rainfall data with topography for catchment analysis.
• Supporting flood risk or water resource management planning in Northern Ireland.

Strengths

• Derived from established data sources: CEH Land Cover 2007, Met Office rainfall, and a 5m DTM.
• Available under the permissive Open Government Licence (OGL-UK-3.0).
• Present on multiple official data platforms (eu_open_data, uk_data), indicating institutional relevance.

Limitations

• Specific column names and data structure are not documented in the provided metadata.
• The core land cover input data is from 2007, which may not reflect current conditions.
• Dataset size, row count, and specific authorship details are not provided.
