Northern Ireland Coastal Orthophotography and LiDAR, 10cm Resolution

OpenDataNI provides orthophotography and topographic LiDAR data from the 2021 NI 3D Coastal Survey. The dataset covers the entire Northern Ireland coastline, including intertidal areas and approximately 200 meters landward of the high water mark. Colour infrared orthophotography imagery was captured with a 10cm resolution.

Use Cases

• Monitor coastal erosion and landform changes based on high-resolution orthophotography.
• Train computer vision models for land cover classification using colour infrared imagery.
• Create detailed 3D terrain models for coastal planning based on the topographic LiDAR survey.
• Analyze intertidal zone vegetation and habitats using the geometrically corrected imagery.

Strengths

• Imagery has a high 10cm spatial resolution.
• Coverage extends across the entire Northern Ireland coastline and intertidal zone.
• Data is ortho-rectified, providing a uniform scale and freedom from distortion.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
