UAV Orthophotos of Grassland with Broad-leaved Dock Plants in Kleve, Germany

João Valente of Wageningen University & Research provides a dataset of orthophotos built from UAV images of a grassland field in Kleve, Germany. The images were captured at flight heights of 10, 15, and 30 meters. Annotations for detected Rumex obtusifolius (broad-leaved dock) plants are included.

Use Cases

• Training object detection models for Rumex obtusifolius based on provided image annotations.
• Evaluating the effect of UAV flight altitude on plant detection accuracy based on imagery from three heights.
• Developing geospatial analysis tools for mapping weed distribution in agricultural fields.
• Benchmarking segmentation algorithms on high-resolution orthophotos of grassland.

Strengths

• Includes annotations for the target plant species, Rumex obtusifolius.
• Imagery was captured at three distinct flight altitudes (10m, 15m, 30m), allowing for comparative analysis.
• Provides orthorectified images (orthophotos) from a specific geographic location in Kleve, Germany.

Limitations

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