Résumé
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 thereef flats ?=> improve coral distribution models and mapping ?
