1m LIDAR Composite DSM & DTM for Scotland

Up to 300,000 laser measurements per second are made of the ground, allowing highly detailed terrain models to be generated. This dataset is a composite of the Environment Agency's LIDAR archive, offering Digital Surface and Terrain Models for Scotland at resolutions from 25cm to 2 meters. The data is managed by the Government Digital Service, though the original source is no longer available on the Defra Data Services Platform.

Use Cases

• Generate high-resolution terrain models for hydrological analysis based on the detailed Digital Terrain Model (DTM) data.
• Analyze urban and vegetation structures for 3D city modeling based on the object-inclusive Digital Surface Model (DSM).
• Create base maps for autonomous vehicle navigation systems based on the precise 1m to 25cm resolution elevation data.

Strengths

• Offers data at four high spatial resolutions: 2m, 1m, 50cm, and 25cm.
• Provides both Digital Surface Models (including objects) and Digital Terrain Models (bare earth).
• Derived from a combination of surveys merged and re-sampled to give the best possible coverage.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last update date is unknown; freshness unverified.
• Column-level documentation is absent; field semantics must be inferred after download.
