Abstract: Wetlands are essential for recreation, habitat, flood mitigation, and reducing pollution in the Great Lakes basin. Existing wetland inventories are outdated, inaccurate, and frequently underestimate the extent of these ecologically significant features. Object-based image analysis (OBIA) and recent advances in the availability of high-resolution stereo satellite imagery and surface elevation mapping approaches have created new opportunities for mapping and monitoring landscape change within the basin. In this presentation, we cover OBIA approaches that leverage high-resolution remotely-sensed data to map and monitor changes along the coasts of the Great Lakes.
