    As a sanity check, I went surfing. It is Wikipedia, but I found some humor
    in the following:
    
    Prime Meridian
    
    "WGS84 longitudes, which are used by satellite navigation systems, differ
    slightly from traditional longitudes. The WGS84 zero meridian is 102.5
    metres (336.3 feet) to the east of the line marked at Greenwich....
    Curiously, whether by accident or design, the location of the WGS84 0�
    meridian is marked in Greenwich by the presence of a waste basket on the
    path leading more or less due east from the observatory containing the
    transit telescope."
