Suffolk County GIS Division



Suffolk County's Division of Geographic Information Services addresses the GIS needs of the County's government, its many municipalities and residents. To serve the County Government, the GIS Division produces and distributes geographic data, creates maps, provides GIS technical support and develops and hosts web-based mapping services catered to the specific needs of interested departments. In addition to distributing geographic data and providing technical support to County departments, the GIS Division assists local governments by holding GIS User Committee meetings, where we work together toward the development of county-wide GIS procedures and establish cost-sharing practices to reduce duplicate spending of common geographic data.
