Scotland 2-Meter LIDAR Digital Elevation Models (DSM & DTM)

Light Detection and Ranging (LIDAR) data collected by the Environment Agency's remote sensing team provides highly detailed terrain models for Scotland. Up to 100,000 ground measurements per second allow for spatial resolutions ranging from 25 centimeters to 2 meters. This dataset is derived from a merged and re-sampled combination of surveys, available as Digital Surface Models (including objects) or Digital Terrain Models (ground only).

Use Cases

• Generate high-resolution terrain maps for flood modeling based on the detailed Digital Terrain Model.
• Analyze vegetation and building heights for environmental or urban studies using the object-inclusive Digital Surface Model.
• Create base layers for 3D landscape visualization and simulation based on the 2m to 25cm resolution data.
• Conduct change detection analysis over time by comparing LIDAR surveys mentioned as part of an archive.

Strengths

• Data offers multiple high spatial resolutions: 2m, 1m, 50cm, and 25cm.
• Derived from a merged and re-sampled combination of surveys to provide the best possible coverage.
• Includes both Digital Surface Models (with objects) and Digital Terrain Models (ground only).

Limitations

• Description metadata is limited; actual data quality, file formats, and size require manual inspection after download.
• Row count and last update date are unknown, which may limit suitability assessment.
• The original data is no longer available on the described platform, requiring users to visit a new portal.
