GNIS (Geographic Names Information System)

The Geographic Names Information System (GNIS) is a comprehensive database maintained by the U.S. Geological Survey that records official names, locations, and details of physical and cultural geographic features across the United States. It includes places like towns, rivers, mountains, and landmarks, providing standardized information to support mapping, research, and navigation. GNIS ensures consistent naming and accurate geographic data, aiding government agencies, cartographers, researchers, and the public in locating and identifying places reliably.
