Model Family Advantages for Looting Detection Disadvantages/Challenges
CNN-based Models (ImageNet Pretrained)
  • Highest F1 (0.926) for subtle, localized signatures.
  • Benefits from ImageNet pretraining (+6-14% F1 improvement).
  • Performance significantly enhanced by spatial masking (+30-45% F1 improvement).
  • End-to-end learning captures complex visual patterns effectively.
  • Requires substantial labeled datasets for optimal fine-tuning.
  • Potential for domain shift from natural images (ImageNet) to satellite imagery.
Traditional ML (with Handcrafted Features)
  • Interpretable features (e.g., GLCM texture, Sobel NIR edge strength).
  • Competitive with foundation model embeddings for localized signals.
  • Lower computational requirements compared to deep CNNs.
  • Lower peak performance than CNNs (F1 0.710).
  • Manual feature engineering is labor-intensive and requires domain expertise.
  • Less effective for capturing highly complex, abstract patterns.
Traditional ML (with Foundation Model Embeddings)
  • Leverages robust pre-trained representations from diverse remote sensing tasks.
  • Reduces the need for extensive domain-specific feature engineering.
  • Often competitive with traditional handcrafted features.
  • Masking can degrade performance for some embeddings, indicating context dependence.
  • Performance generally lower than fine-tuned CNNs.
  • May struggle with highly localized signatures if embeddings are too global.

Real-world Application: Safeguarding Afghanistan's Cultural Heritage

Our framework was rigorously tested on the largest dataset of its kind, encompassing 1,943 archaeological sites across Afghanistan. This includes 898 looted and 1,045 preserved sites, with multi-year PlanetScope imagery from 2016-2023. The approach demonstrates significant potential for scalable monitoring in remote and conflict-affected regions, providing critical insights for timely cultural heritage protection.

Key Findings:

  • Largest Dataset: Utilized 1,943 sites in Afghanistan (898 looted, 1,045 preserved) over 8 years (2016-2023).
  • High-Resolution Imagery: Employed PlanetScope monthly mosaics (4.7m/pixel) for detailed analysis.
  • Spatial Masking Crucial: Manual spatial masks significantly improved F1 scores by 30-45% by focusing on relevant site areas.
  • Temporal Consistency: Identified that training on single, temporally consistent year imagery (e.g., 2020) reduced label noise and improved performance.
  • Practical Scalability: The pipeline offers a robust solution for large-scale, remote archaeological site monitoring where ground-based methods are infeasible.
