Cover Story: Coral reefs are in decline worldwide and face stresses at all scales, from coastal development and overexploitation to global warming and ocean acidification. Monitoring reef status by manual surveys provides data at localised scales which is not cost-effective for the regional and global scales at which reefs are threatened. Satellite imagery has now been leveraged for reef applications for over 40 years with a multitude of sensor and algorithm developments. We review the historical and state-of-the-art achievements and remaining challenges, over the range of monitoring objectives from the physical and biological composition of the reef to the ocean environment in which they occur. Of increasing importance is the aim to go beyond basic maps, to concepts relevant to stakeholders, policy makers and public communication: such as biodiversity, environmental threats and ecosystem services.
