 This special issue of remote sensing explores the potential of remote sensing technology to accurately and consistently detect wetlands across different regions and climates. The papers focus on advances in remote sensing techniques, such as multispectral imagery, lidar, and hyperspectral imaging, which have been used to identify wetlands in various environments. Additionally, the papers discuss the development of data products and approaches for regional to global long-term monitoring of wetland landscapes. This article was authored by Alisa L. Gallant.
