Elevation data became flood-risk intelligence.

High-resolution terrain data across Scotland and Wales was processed into DSM and DTM models to support national flood forecasting, mitigation and disaster planning.

The challenge

Existing elevation data lacked the resolution and currency required for accurate hydrodynamic modeling.

The mapped areas spanned varied terrain, so consistency and scale were both operational risks.

The approach

SBL processed high-resolution terrain inputs into DSM and DTM outputs with repeatable quality checks.

The workflow supported large-area delivery while preserving the accuracy needed for flood modeling.

The result

Flood planning teams received updated terrain models that could improve forecasting and resilience decisions.

• Large terrain coverage was processed for flood-risk workflows.
• Surface and terrain models supported different planning needs.
• Consistent quality controls helped manage varied terrain.
• The data improved the foundation for mitigation and early-warning work.
