Satellite-Based Detection of Looted Archaeological Sites

The Rundown

Microsoft Research unveiled a important approach to monitor looted archaeological sites using satellite imagery. Their scalable pipeline, leveraging PlanetScope's 4.7m/pixel monthly mosaics, analyzes a curated dataset of 1,943 sites in Afghanistan — 898 of which have been looted. The model employs end-to-end CNN classifiers trained on raw RGB patches, achieving an impressive F1 score of 0.926, significantly outperforming traditional machine learning methods that only reached 0.710. This innovation not only enhances the ability to protect cultural heritage but also sets a new benchmark for remote sensing applications in archaeology.

The details

The CNN model trained on RGB patches achieved an F1 score of 0.926, while the best traditional ML setup scored only 0.710.
The dataset included 898 looted and 1,045 preserved archaeological sites, providing a comprehensive training ground for the model.
Ablation studies confirmed that ImageNet pretraining and spatial masking were critical to achieving high performance.
Geospatial foundation model embeddings showed competitive results, indicating that looting signatures are highly localized.

Why it matters

This research positions Microsoft as a leader in utilizing AI for cultural preservation. The ability to detect looted sites at scale can significantly aid governments and organizations in safeguarding heritage, potentially influencing policy and funding in archaeology.
