 Mangrove ecosystems are important coastal wetlands that provide various ecological and economic services. However, they are threatened and vulnerable, with a dramatic decline during the last half century. Remote sensing is a valuable tool for providing spatio-temporal information on mangrove ecosystem distribution, species differentiation, health status, and ongoing changes of mangrove populations. Various sensors such as aerial photography, high- and medium-resolution optical imagery, hyperspectral data, and active microwave, SAR, data can be used for remote sensing studies on mangroves. Recent climate change and discussions of the services provided by these ecosystems have increased the focus on remote sensing studies in coastal zones. This review paper aims to provide a comprehensive overview and sound summary of all of the work undertaken, addressing the variety of remotely-sensed data applied for mangrove ecosystem mapping, as well as the numerous methods and techniques used for data analyses, and to further discuss their potential and limitations.
