Just did; tiny difference, much smaller than the error. I guess this
means it's my raw data (the northings/eastings) that are a bit off :-(
I wonder why that would be? I also have the postcodes, anyone have a
ballpark figure for how much the PO charge for postcode->lat/long
tables, and how accurate those would be?
Thanks for the suggestion, anyway!
