Lough Neagh Network Contribution: High Contribution Area Scores

Lough Neagh Network Contribution data contains scores exported from 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 (DTM). 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-contribution areas for surface water flow based on integrated land cover, rainfall, and terrain scores.
• Visualizing hydrological network contribution zones in web maps for regional planning.
• Incorporating standardized contribution scores into environmental dashboards for monitoring.
• Analyzing the relationship between land cover (2007), average rainfall, and terrain on water network contributions.

Strengths

• Derived from established inputs: CEH Land Cover 2007, Met Office average rainfall, and a 5-meter DTM.
• Methodologically defined 'High contribution' boundary using a statistical threshold (+1 standard deviation).
• Available on multiple open data platforms (UK and EU), indicating institutional validation and accessibility.

Limitations

• Specific column names and data structure are unknown, limiting precise understanding of the score values.
• The dataset's size (number of rows/records) and exact file size are not provided.
• The primary land cover input is from 2007, which may not reflect current conditions.
