Northern Ireland Coastal Orthophotography with 10cm Resolution

Northern Ireland's entire coastline, including intertidal areas and approximately 200 meters landward of the high water mark, is covered by this orthophotography. The geometrically corrected aerial imagery was captured as part of the 2021 NI 3D Coastal Survey with a 10cm resolution. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license.

Use Cases

• Monitor coastal erosion and landform changes based on high-resolution aerial imagery.
• Classify land cover and habitat types in the coastal zone based on natural colour imagery.
• Create accurate base maps for coastal planning and management based on ortho-rectified photos.
• Train object detection models for coastal infrastructure based on 10cm resolution imagery.

Strengths

• Imagery has a uniform scale and is free of distortion due to ortho-rectification.
• Provides 10cm resolution, suggesting a high level of spatial detail.
• Covers the entire Northern Ireland coastline, including the intertidal area.

Limitations

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