Abstract

Eyes on space: A 50-year critical assessment of satellite Earth Observation in flood disaster management RSS-Hydro evaluates the evolution and effectiveness of satellite Earth Observation in flood disaster management, highlighting advancements in technology and addressing ongoing challenges such as urban mapping limitations and data communication. SINCE the launch of the early Landsat missions, satellite Earth Observation (EO) has transitioned from a niche scientific tool to the backbone of global disaster resilience, or so it seems. This article critically examines the value of EO data over the last half-century, specifically regarding flood disasters. While technical capabilities have grown exponentially – moving from grain-heavy 80m resolution to real-time artificial intelligence (AI)-processed imagery – significant hurdles in latency, urban ‘shadowing’, and the ‘last mile’ of data communication remain.
