Oh John, tut tut. The grid reference is TR 03349 70643, you've quoted the co-ordinates.
To be fair though, unless you are into navigation there are a number of competing and confusing systems. The national grid simplifies things for land positions within the UK. It projects the UK in a modified Mercator projection onto a series of 100km x 100km squares identified by a pair of letters. Each square is progressively divided, a 10 figure reference like the above identifies a 1 m square. The co-ordinates are the traditional latitude and longitude. GSV uses these since they apply globally and are understood in all countries. When quoted decimally positive is North and East, negative South and West; for instance the Black country Museum is at 52.5200,-2.0755, we are just lucky in Kent that everything is positive.
I was born in Sheffield but at the age of 3 moved to the Black Country. We were just about 3 miles NNW from the museum in a place called Hurst Hill. We lived there for 6 years before moving back to a different part of Sheffield, then Middlesbrough, then Whitley Bay and Dad's last posting was to Kingswinford back on the periphery of the Black country. I've worked in both Middlesbrough and Whitley Bay before eventually getting a job in Kent. The plan was to stay a couple of years, well nigh on 40 years have passed and I'm still here!
