Strangford Network Contribution: High Surface Water Flow Areas

Northern Ireland's Strangford Lough region is covered by this geospatial dataset of network contribution area scores. The scores, derived from SciMAP application outputs within SAGA GIS, 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 is defined as areas scoring above +1 standard deviation of the score distribution.

Use Cases

• Identifying high-risk surface water flow zones for flood mitigation planning based on contribution scores.
• Visualizing hydrological connectivity patterns in web maps or dashboards for environmental reporting.
• Analyzing the relationship between land cover, rainfall, and topography on surface water contribution.

Strengths

• Derived from established, multi-source inputs including CEH Land Cover 2007, Met Office rainfall data, and a 5-meter DTM.
• Available under the permissive OGL-UK-3.0 license, facilitating reuse and analysis.
• Cross-platform presence on uk_data and eu_open_data indicates recognized utility and stability.

Limitations

• Specific column names and data structure are not documented, hindering precise technical analysis.
• The primary land cover input is from 2007, which may not reflect current conditions.
• No row counts, file sizes, or detailed authorship information are provided across sources.
