CT DEEP GIS Open Data

The Connecticut Department of Energy & Environmental Protection (DEEP) offers an extensive GIS Open Data portal to support its critical mission of environmental protection and preservation. This platform is integral to managing and disseminating geographic information across the state, enabling rapid integration and analysis of diverse spatial datasets for any selected geographic area.

DEEP GIS plays a vital role in developing and maintaining a statewide automated geographic storage and retrieval system. This system facilitates the sharing of authoritative geospatial information with a broad network of partners, including federal, state, and municipal government agencies such as the U.S. Geological Survey, Environmental Protection Agency, and Connecticut Department of Transportation.

Users can explore various environmental datasets, including recent updates like the Natural Diversity Database, Cold Water Sites Set, Connecticut Dams, and Alternate Groundwater Protection Criteria Area (GWPC). This resource empowers both government entities and the public with crucial data for informed decision-making regarding Connecticut's natural resources and environmental management.
