 This research examined the use of remote sensing data to map wetlands at the landscape scale. The researchers compared the accuracy and confidence of various data sets and selected key input variables such as terrain, soil characteristics, and remotely sensed data. They also identified the most effective combination of data sources and seasons for accurate wetland classification. This information will help natural resource managers monitor wetland ecosystems and design a system for consistent operational mapping of wetlands across landscapes.
