Good morning Borry.
Our favourite source of stone age thinking and knowledge, the Daily Mail, brings news of a new circle thingy with henges and whatever.
Apparently it has been found on a Kentish council estate. So no megalithic snobbery there.
The good news is brought by our favourite organ from work done by SWAT archaeology who specialise in finding holes to dig.
Here is the Mail's article which has a video which must have been taken by a flying frog if the small shadow is to go by. Must have stuck a webcam on its head then told it to jump.
http://www.dailymail.co.uk/sciencetech/ ... ourne.htmlThe SWAT site is here. Lots of downloadable pdfs at the bottom of the page. I haven't yet had time to look at them so I'm not sure what they all contain.
Anyway Sittingbourne could provide one of your latitude markers perhaps.
http://www.swatarchaeology.co.uk/They say that they are using the GPS system to pinpoint positions etc. And advise similar minded people to use this resource. Not sure if it costs.
'Swat Survey uses the National GPS Network to obtain accurate positions in the national coordinate system. The Ordnance Survey is fully adopting GPS positioning as the basis of all national coordinate systems. All surveyors who want to take advantage of the new infrastructure will therefore need access to survey grade GPS equipment.'
Here's a pdf with details
http://www.swatarchaeology.co.uk/pdf/assesments/GPS.pdfHere's a page from the Ordnance Survey with more information on these systems.
