- The database assigns a unique, permanent feature identifier, the Feature ID, as the only standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. The GNIS collects data from a broad program of partnerships with Federal, State, and local government agencies and other authorized contributors... Any person or organization, public or private, may make inquiries or request the Board to render formal decisions on proposed new names, proposed name changes, or names that are in conflict.
Best practice is to copy this tag to new geometry that represents the same feature. Please do not remove this tag from an object without understanding the implications. If the real-world object no longer exists, then delete the OSM object including the identifier. For an overview of dealing with GNIS tagging, see GNIS.
