The Wisconsin DNR's Surface Water Data Viewer (SWDV) is an interactive map that displays primarily statewide water-related data.
The Coastal Wetland and Tributary Decision Support Tool for the Duck-Pensaukee is an interactive, online map designed to help conservationists prioritize sites in the Duck-Pensaukee Watershed for land protection and restoration projects. The Duck-Pensaukee Watershed is a sub-watershed of Green Bay and faces serious conservation challenges. These challenges include the loss of coastal wetlands, which clean polluted water, intercept waste, protect our shorelines from erosion, provide food and shelter for migratory birds, and serve as nurseries for fish and other aquatic life.
The Estuary Data Mapper (EDM) is a free, interactive, downloadable application under development at the US EPA that allows users to quickly and easily retrieve, view, and save subsets of online US coastal estuary-related data. It is intended to help researchers, managers, and decision-makers find and map data relevant to coastal estuary systems.
