The Wisconsin Coastal Atlas is a technology platform that enables people to explore and analyze coastal issues, share coastal data, and inform decision-making about sustainable use of the Great Lakes. It is intended for use by coastal resource managers, planners, researchers, educators and citizen scientists. The atlas serves as a gateway to interactive maps and decision support tools relevant to Great Lakes management and provides access to place-based learning resources about coastal issues in Wisconsin. Development of the Wisconsin Coastal Atlas began in February 2010 with funding from the University of Wisconsin Sea Grant College Program.
