Statewide GIS
- CT ECO/DEEP - Connecticut Environmental Conditions Online (CT ECO) is the collaborative work of the Connecticut Department of Energy and Environmental Protection (DEEP) and the University of Connecticut Center for Land Use Education and Research (CLEAR) to share environmental and natural resource information with the general public. NOTE: This is not a street map, but it does contain streets. It is a useful resource, but should not be the determining factor when making mapping decisions.
