Lough Melvin And Arney: High Network Contribution Areas

Network contribution area scores derived from SciMAP application outputs within SAGA GIS identify zones with high hydrological influence. The scores integrate land cover data from CEH Land Cover 2007, average rainfall from the Met Office, and a 5-meter Digital Terrain Model. High contribution boundaries are defined statistically as areas exceeding one standard deviation above the mean score distribution.

Use Cases

• Visualizing high hydrological contribution zones in web maps based on integrated environmental scores.
• Incorporating layer into dashboards for environmental monitoring and analysis.
• Assessing surface water connectivity risks using combined land cover, rainfall, and topography data.
• Identifying areas for targeted land management to influence catchment runoff.

Strengths

• Derived from multiple authoritative inputs: CEH Land Cover 2007, Met Office rainfall data, and a 5-meter DTM.
• Available on multiple open data platforms (uk_data, eu_open_data), indicating established utility.
• Data is downloadable and licensed under OGL-UK-3.0 for open use.

Limitations

• Specific column names and dataset size (row count, file size) are not provided in any source.
• The temporal coverage is limited, with core input data (land cover) dated to 2007.
• The description is repeated verbatim across all entries, suggesting sparse or identical metadata.
