Lough Neagh Environs Terrain and Surface Elevation Models from 2017 LIDAR

Airborne LIDAR survey systems captured terrain and surface elevation data for the Lough Neagh area in April 2017. Data is provided in large LAS and ASCII format files, with tiles grouped into four quadrant groups covering 1km x 1km areas. The dataset is published by OpenDataNI under the OGL-UK-3.0 license but is not officially supported.

Use Cases

• Generate 3D landscape visualizations based on the 1m x 1m grid Digital Terrain Model (DTM).
• Model flood risk and water flow using the detailed elevation data of the Lough Neagh environs.
• Analyze land surface changes by comparing the 2017 Digital Surface Model (DSM) with other temporal data.
• Create base maps for environmental planning using the georeferenced point cloud and raster data.

Strengths

• Data provides both Digital Terrain Models (DTM) and Digital Surface Models (DSM) for comparative analysis.
• Elevation data is captured at a high spatial resolution of 1 meter per grid point.
• Data is available in both industry-standard LAS and widely compatible ASCII formats.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is marked as 'not supported', indicating limited official guidance or updates.
