LiDAR Digital Terrain Model for South West England

9424 km² of high-resolution LiDAR-derived Digital Terrain Model data covering land west of Exmouth in South West England. The dataset represents bare earth topography and is an outcome of the Centre for Ecology & Hydrology South West Project.

Use Cases

• Model hydrological flow and flood risk using the bare earth elevation data from the Digital Terrain Model.
• Analyze topographic changes by comparing this Digital Terrain Model with the available Digital Surface Model for the same area.
• Integrate elevation data for land-use planning and environmental modeling in the South West England and Tamar catchment regions.

Strengths

• Covers a 9424 km² area with high-resolution spatial data.
• Provides a dedicated Digital Terrain Model representing bare earth height, distinct from surface features.
• Associated Digital Surface Model data for the same area is available for comparative analysis.

Limitations

• Data format and resolution specifics are not detailed in the provided input.
• The dataset's spatial coverage is limited to South West England west of Exmouth.
• Sample data and technical metadata (e.g., point density, vertical accuracy) are unavailable for review.
