Geographic Information Systems
Geographic Information Systems at DEEP plays an important role in the DEEP's mission of protecting and preserving the environment for present and future generations. DEEP develops and maintains a statewide automated geographic storage and retrieval system that can rapidly integrate and analyze large amounts of spatial map and file data over any selected geographic area.
DEEP develops and shares geospatial information with federal, state, and municipal government agencies such as the U.S. Geological Survey, Environmental Protection Agency, Federal Emergency Management Agency, Connecticut Department of Public Health, Connecticut Department of Transportation, and the Connecticut Office of Policy and Management.
Visit our GIS Data Download Page
Our GIS Data page provides a wealth of GIS data available for download in NAD83 coordinate system via an ftp site. This allows for faster downloads for larger files such as orthophotos and topographic data. Check out GIS Data for DEEP's environmental resource downloads. Please note that as of October 1st, 2020 the GIS Data Download Page will be completely replaced by the GIS Open Data Website, and will no longer be accessible.
Visit our GIS Open Data Website
Our new GIS Open Data Website uses ArcGIS Hub functionality to showcase a dedicated website for spatial data viewing and download.This separate website will take the place of our above GIS Data Download Page on October 1, but for now, both will be available. Please note that the data sets from both resources will be kept up to date simultaneously. Check out our GIS Open Data Website for a more interactive experience!
