Remote Sensing for Wetland Mapping and Monitoring: Gaps and Future Directions

Wetlands provide various goods and services, including habitat, medicine, food, flood mitigation, and other local and global environmental benefits. However, the ecosystem functions of wetlands have been at risk due to human interference and climate change. This review article highlights the application of remote sensing techniques in wetland monitoring and mapping. It emphasizes the use of satellite imagery and the advancement of classification methods to delineate wetland boundaries and assess land‐use dynamics and vegetation health. We observed a significant study on wetland ecosystem mapping with Landsat and Sentinel satellite data. Despite advancements in various remote sensing tools and techniques for wetland monitoring, challenges persist, including cloud cover interference (primarily during rainy seasons), limited access to open data, the need for high‐resolution data and the requirement for more accurate classification methods. Moreover, this review highlights the gaps in current remote sensing applications and suggests future research directions to improve wetland ecosystem management and conservation plans.
