River Basin Terrain and Surface Elevation Models from 2009-2010 LIDAR

Terrain and surface elevation models for river basins derived from airborne LIDAR surveys. Data is provided in 1km x 1km tiles containing a 1m x 1m grid of elevation points, with some areas also offering the original 0.2m spaced point cloud files. This dataset is provided by OpenDataNI under the Open Government Data Licence and was last updated on 2026-07-08.

Use Cases

• Flood risk modeling based on high-resolution Digital Terrain Models (DTMs) of river basins.
• 3D visualization of land surfaces based on the 1m x 1m grid elevation data.
• Hydrological analysis based on the detailed terrain models of river basins.
• Comparing terrain and surface features using the paired DTM and Digital Surface Model (DSM) data.

Strengths

• High-resolution 1m x 1m elevation grid for detailed terrain analysis.
• Includes original 0.2m spaced point cloud data for 2009-2010 acquisitions, offering raw measurement detail.
• Data is organized into downloadable 1km x 1km tiles grouped by geographic area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes this is 'not a supported LPS product', suggesting limited official support.
• Row count and total dataset size are unknown, which may limit suitability assessment.
