A geographic information system (GIS) is a computer system that integrates hardware, software, and data in
order to capture, store, check, and display geographic, or location-based, data. A GIS allows us to visualize, question, analyze, and interpret data to understand relationships, patterns, and trends in the form of maps.
GIS has become an integral tool at the City of Three Rivers, facilitating the production of maps and spatial analyses in support of internal City departments and the citizens of our community. The GIS Division is housed in the City’s Department of Public Services. For GIS or map-related questions, please call DPS at (269) 273-1845.
