US National Park Service Tagging: Boundaries
Official Park Boundaries
The US National Park Service only recognizes park boundaries published by the [NPS Land Resources Division.]
We recommend that OSM Mappers editing NPS boundaries use only the official published park boundaries produced by the National Park Service. Editing park boundaries sourced from local parcel records, etc, may lead to boundary encroachment issues that only a professionally licensed surveyor can resolve.
