Moyola Network Contribution: Hydrological Surface Flow Analysis

Network contribution area scores were exported from the SciMAP application outputs within SAGA GIS. The scores were based on inputs from CEH Land cover 2007, Met Office average rainfall and a 5 meter Digital Terrain Model. The data layer is intended for visualization in web maps, use in dashboards, and is downloadable in multiple geospatial formats.

Use Cases

• Identifying high surface water contribution zones for flood risk modeling based on terrain and rainfall inputs.
• Visualizing hydrological connectivity for environmental impact assessments in web maps.
• Incorporating land cover and rainfall data into watershed management dashboards.
• Analyzing terrain-driven surface flow patterns using a standardized contribution score.

Strengths

• Derived from specific, named input datasets: CEH Land Cover 2007, Met Office average rainfall, and a 5m DTM.
• Cross-platform presence on eu_open_data and uk_data indicates established use and availability.
• Explicitly defined methodology: High contribution boundary set at +1 standard deviation of score distribution.

Limitations

• No column names or schema details are provided, limiting understanding of the data structure.
• Key metadata such as row count, file size, and specific author are consistently missing across all sources.
• The most recent update date (2026-07-08) appears to be a future date, suggesting potential metadata errors.
