In the case of underground structures such as subway stations (Underground stations in UK parlance), where the surface-level entrances may be offset from the station proper and connected to it by tunnels, it may be difficult to establish the exact longitude/latitude of the station, as opposed to the longitude/latitude of its entrances.  GPS units don't work while underground.
