Geometry licence: all-rights-reserved
Use scope: Campus locator
Scope class: selected_named_university_host_campus_point
Authority: Compiled location reference
Source entity: Campus
Method: direct_google_maps_selected_named_host_campus_coordinates
Derivation: direct_geometry
Precision scope: Wider Yokohama university host-campus marker for the TSUBAME4 data center in G4-A. It does not map the G4-A building, machine room, cooling plant, entrance or surveyed campus boundary.
Horizontal uncertainty: Not reported
Google provides no measured accuracy for the campus feature or offset to G4-A. Decimal precision is not survey accuracy; the actual building position is not selected.
Geometry evidence: d3465bcf

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
