Geographic Information Systems Office

A geographic information system (GIS) uses geospatial technology for analyzing and graphically depicting how cities, towns, and rural areas work and interact. It helps us understand spatial relationships between locations and can provide insights into development and planning issues. The GIS Office’s mission is to improve the coordination of geospatial data throughout the state. Our aim is to ensure everyone has access to authoritative data sets. This includes executive agencies, research academics, regional planners, municipal governments, and more.
