WATCH: Wide-Area Archaeological Site Tracking for Change Detection
Researchers introduce WATCH, a satellite-based framework using foundation models to detect disturbances at archaeological sites across months and years. The system combines three approaches—temporal embedding distance, self-supervised change detection, and weakly supervised learning—achieving up to 92.5% accuracy within three-month tolerance windows when monitoring 1,943 Afghan sites and cross-validating in Syria, Turkey, Pakistan, and Egypt.
