Earth Observation (EO) refers to the collection of information about Earth’s land, oceans, and atmosphere via remote sensing technologies – primarily satellites, but also drones, aircraft, and ground sensors. In the context of disaster management, EO provides a “big picture” perspective of events as they unfold. This real-time, wide-area view is transforming how we prepare…
