Researchers have developed GeoQuery, a novel zero-shot retrieval system designed for searching vast archives of satellite imagery, particularly for crisis response applications. This system bypasses the need for extensive paired data and compute by using prompt-aligned text proxies to bridge the gap between visual foundation models like CLAY and natural language queries. GeoQuery demonstrated strong performance on disaster-related queries, achieving significant accuracy in identifying vulnerable areas during simulated and real-world events, and has been integrated into the ECHO crisis response system.
