CT GIS Office Guidance Documents

These guidance documents are provided by the Connecticut's GIS Office to support our role in coordinating a consistent, high-quality geospatial framework for the state. As part of our responsibilities, we maintain statewide data standards, support data sharing and integration across agencies and municipalities, and manage the state’s geospatial data clearinghouse. This guidance is intended to help all levels of governments and partners align their GIS efforts, improve data quality, and contribute to a more connected geospatial ecosystem in Connecticut.
