Aerial Laser and Photogrammetry Survey of Dublin City, 2015

The 2015 Aerial Laser and Photogrammetry Survey of Dublin City Collection Record indexes a suite of high-density remote sensing data for a 2km² area of Dublin, Ireland. Collected in March 2015, the data include over 1.4 billion aerial laser scanning points and imagery from 41 flight paths. This dataset was created by Debra F. Laefer with funding from the European Research Council and Science Foundation Ireland.

Use Cases

• Generate 3D city models based on the high-density point-cloud and imagery data.
• Analyze urban morphology and building structures based on the aerial laser scanning data.
• Train machine learning models for object detection in urban environments based on the ortho-rectified and oblique imagery.
• Conduct change detection studies by comparing this 2015 survey with newer data.

Strengths

• Contains over 1.4 billion laser scanning points, indicating high density.
• Data is structured by both flight paths and 500x500 meter tiles for flexible access.
• Includes multiple data types: 3D point-clouds, full waveform ALS, ortho-rectified rasters, and oblique images.

Limitations

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