LiDAR Digital Surface Model for Luing and Slate Islands at 50cm Resolution

25 last echoes per square meter on average were collected for a 20 km² survey on September 9, 2020. The Digital Surface Model (DSM) was commissioned by the Luing History Group and surveyed by Fugro, covering the Slate Islands off Scotland's west coast. The data offers complete coverage of Luing and Torsa, with partial scans of Fladda, Belnahua, Seil, and Shuna.

Use Cases

• Analyze coastal erosion and terrain changes based on the high-resolution DSM.
• Model flood risk and water drainage patterns based on the detailed surface elevation.
• Map vegetation and built structures based on the 50cm resolution surface model.
• Support archaeological or historical landscape studies based on the complete island coverage.

Strengths

• Survey covers approximately 20 km² with complete coverage of Luing and Torsa.
• Data has a high average point density of about 25 last echoes per square meter.
• The resulting Digital Surface Model is at a 50cm spatial resolution.

Limitations

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