Well... I'm close to Dublin now, will give a try on GMT... I went to Belem do Para, Brasil, close enough to que ecuador line... It's sooooo daaaaaaamn hot! I hope I NEVER go back there. Maybe somewhere cold (is there any high mountain over the ecuador line?) but never back to Amazonia! On 10 April 2017 at 17:24, Marshall Eubanks <marshall.eubanks@gmail.com> wrote:

And you should also note that the location where they charge you to take that photograph is about 20 meters to the west of where it should be. At least, I presume my modern smartphone's GPS is fairly accurate, as well as having looked it up on Google Earth later.
I always thought that the meridian line as marked is 0° in *OSGB36*, not WGS84 which is what GPS uses:

George Kaplan and his colleagues went into why the "Greenwich Meridian" moved pretty exhaustively.
