Completely stumped and Google is not my friend this evening.
If reading a simple 4 digit grid reference from a map, it is obvious when the feature is in the middle of the square so for example the Church is at 1630.
But what happens when the feature straddles 2 lines equally? So the caravan site - is it at 1531 or 1631?
Really feel like I should know this but any help gratefully received. Thanks
