 This special issue of remote sensing explores the potential of remote sensing technology to accurately and consistently detect wetlands across regions and continents. The papers focus on advances in remote sensing techniques and data products for regional to global long-term monitoring of wetland landscapes, as well as emerging technologies and sensors slash multi-sensor approaches for more accurate and consistent detection of wetlands. Finally, case studies demonstrate how remote long-term monitoring of wetland landscapes can reveal changes that correspond with changes in land cover and land use and or changes in climate.
