This is my granddaughter at Flamstead House, Greenwich Park close to the meridian line a while back.

And then astride the East and West hemispheres as the Meridian line heads off to East Grinstead :okay:

What does the yellow denote? Are they older telecoms markers?
Used to be Gas, but now seems to be used to mark a currently used plate.

We've a mix of white and/or yellow plates for fire hydrants. White are no longer used plates.

Is this a bit too much marking in one area? And why do two seperate sites give different locations, and images for the same FBM?

Am I overthinking this!!
Yes,

As I noted somewhere in the deep distant past in the thread, OS can get it wrong, bridge mark about 5 miles away as crow flies, If you look at the varying slight differences in GPS readings at some marks/trigs plus I think some online maps may have slightly inaccurate 'formulae' to work out position. I've found in the past some of the conversion sites from OS to lat/long can differ greatly (geocaching demand lat/long). I use the OS position from mthe OS databse, it gets you to the area. Trying to understand the hint, well.

or like me, getting the whole OS database northings wrong when converting database at first, **it happens.

Each of the trig points are listed under their own numbers, with a seperate logging page on the site.

Two sites give two seperate FBM(They don't even look the same) for the same area, less than 100 yards apart, but both sites list the same FBM?

Worst part is, some are logging the FBM as being in Lancashire!

Possibly a mistake, the wrong photie uploaded.
I did that on the benchmark site, wrong location info but a quick email and got it fixed.

Have Lancashire their own FBM? Blasphemy LOL
