Lough Melvin And Arney Network Contribution: High Surface Water Connectivity Areas

Network contribution area scores were exported from the SciMAP application outputs within SAGA GIS. The scores are based on inputs from CEH Land Cover 2007, Met Office average rainfall, and a 5-meter Digital Terrain Model. The 'High contribution' category boundary was determined by selecting areas with scores greater than +1 standard deviation from the distribution mean.

Use Cases

• Identifying high-priority areas for water resource management based on combined land cover, rainfall, and topography.
• Visualizing potential surface flow contribution zones for watershed dashboards.
• Supporting environmental network analysis for conservation planning in the Lough Melvin and Arney region.

Strengths

• Derived from multiple authoritative input datasets (CEH Land Cover 2007, Met Office rainfall, 5m DTM).
• Available in multiple geospatial formats (e.g., GeoJSON, SHP, GPKG) for broad tool compatibility.
• Cross-platform presence (eu_open_data, uk_data) indicates established use and importance.

Limitations

• Column names and specific data schema are not provided in any source.
• The primary input land cover data is from 2007, which may not reflect current conditions.
• Metadata for size, row count, and author is consistently missing or listed as 'None'.
