Baseline Wetland Type and Land Cover Map of the Great Lakes Basin, 2010

This dataset holds maps of land cover and wetland ecotype for the Great Lakes Basin (GLB) circa 2010. The data were derived from multi-season L-band SAR, Landsat 5 optical imagery, and thousands of field training data samples. The dataset includes detailed landcover maps of shorelines of each of five Great Lakes along with a land cover map of the entire GLB. This is the first binational map of the GLB that specifically depicts native wetland ecotypes and monocultures of invasive wetland plants (Phragmites australis and Typha spp.). The goal of the effort was to improve understanding of nutrient flow and transport of water across the landscape to the coasts and the processes at the land-water interface in wetland ecosystems that lead to the success of invasive species. The data are provided in Cloud-optimized GeoTIFF (COG), shapefile, comma separated values (CSV), and text file formats. An associated report is included in PDF format.
