(need to press the ETRS89 geodetic button to get it to DMS link has gone a bit mad)
the above is a link to the OS site but it changes world GPS long & Lat D,M,S into OS coords and vice versa which is helpful if you have a a basic GPS or mobile phone that gives long & lat DMS.
just jot down the long & lat DMS of the start / end of the green lane then put it into the above to get the OS coords for the lane then put the OS into http://www.streetmap.co.uk/ enter the OS and you have a map of where you have been.
long winded i agree but its a cheap start???
there is an excel sheet you can download to work out the conversion but it isnt straight forward
