South West England is covered by a high-resolution LiDAR-based Digital Surface Model (DSM) dataset. It captures surface heights, including buildings and vegetation, across a 9424 km² area west of Exmouth. The dataset is part of the CEH South West Project outcomes.
Use Cases
- Extract building footprint heights from the DSM to model urban density.
- Analyze vegetation canopy structure by comparing DSM heights with a corresponding Digital Terrain Model (DTM).
- Model flood risk in the 9424 km² region using surface elevation data to simulate water flow over terrain and built features.
Strengths
- Covers a substantial 9424 km² geographic area.
- Provides high-resolution spatial data derived from LiDAR.
- Includes height data for surface features like buildings and vegetation.
Limitations
- Spatial coverage is limited to South West England, west of Exmouth.
- Data is packaged in a ZIP format, requiring extraction and specialized GIS tools for use.
