LIDAR Composite Coverage and Extents for Scotland

A shapefile dataset from the Environment Agency's archive shows the tile extents used to create a composite LIDAR Digital Surface and Terrain Model for Scotland. The underlying LIDAR data is collected via airborne laser scanning, capturing up to 300,000 measurements per second to generate terrain models at resolutions from 25cm to 2 meters. Data is provided by the Government Digital Service and is accessed via the Scottish Remote Sensing Portal.

Use Cases

• Assess terrain coverage for a specific region based on the tile extents shapefile.
• Generate high-resolution elevation models for hydrological analysis based on the 25cm to 2m resolution LIDAR data.
• Create 3D visualizations of landscapes and built structures using the Digital Surface Model which includes buildings and vegetation.
• Perform terrain analysis for engineering projects using the object-removed Digital Terrain Model.

Strengths

• Data is available at multiple high spatial resolutions: 2m, 1m, 50cm, and 25cm.
• LIDAR collection captures up to 300,000 ground measurements per second.
• Provides both surface models (including objects) and terrain models (ground only).

Limitations

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