Urban Tree Cover in Wales with Point and Polygon Layers, 2018

Urban Tree Cover 2018 updates data on Urban Tree Canopy Cover in Wales, highlighting changes since 2013. The spatial dataset from the Government Digital Service consists of two layers: points for individual trees and polygons for groups of trees. It provides a snapshot of the extent, location, and provision of urban tree cover for 2018.

Use Cases

• Assess changes in urban tree canopy extent and location based on the update from 2013.
• Analyze the spatial distribution of individual trees based on the point layer.
• Evaluate the coverage and density of tree groups based on the polygon layer.
• Model ecosystem service provision from urban tree cover based on the dataset's scope.

Strengths

• Provides a temporal comparison by updating data from a previous study in 2013.
• Contains two distinct spatial data layers (points and polygons) for different analysis scales.
• Focuses on a specific, defined geography (Wales).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count and file size are unknown, which may limit suitability assessment.
