Summary
| Description |
English: Blackwall: Virginia Quay and the Greenwich Meridian The line down the middle of the avenue represents the Greenwich Meridian, and carries on up the building in the distance. Incidentally don't take your GPS receiver to this line and expect it to read 0˚ 00' 00".00000 W longitude! This is because the GPS system uses World Geodetic System 1984 (WGS84) longitudes which are defined, simply, in terms of the geometric centre of the Earth, whereas the Greenwich Meridian is defined in terms of the gravitational centre of the Earth, which is slightly different. 0˚ 00' 00".00000 W longitude on your GPS should appear about 100 metres east of this location, near the Virginia Quay memorial, whereas you should read about 0˚ 00' 05".7 W longitude here on this line.
As an aside (!) this is the Barratt-built Virginia Quay housing development. |
