Coral reef ecosystems are facing increasing pressures and disturbances, leading to a worldwide degradation of their status • Optical remote sensing is commonly used to map and monitor coastal benthic habitats. • Hyperspectral aerial images, have been used to monitor the evolution of living corals over the reef platforms of Reunion Island • In 2022 correlations with spectral indices computed from high and very high resolution satellite images (Pléiades, SPOT6/7, Sentinel-2) and historical and field data have been established. Could new Pléiades Neo images, with enhanced spectral and spatial resolutions, be used to: => detect spatial and temporal evolutions of geomorphological and biological features across the reef flats ? => improve coral distribution models and mapping ?
