Great Lakes GIS Online|
The Great Lakes GIS Online project partners--a variety of U.S. and Canadian federal and state agencies--are populating an online library with numerous data sets, including Great Lakes shoreline, soils, land use and land cover, hazardous waste sites, demographics, watersheds and transportation. The project goal is to provide user-friendly online mapping of many of these files by developing and maintaining a state-of-the-art online mapping system.
