The Ordnance Survey maintains a mapping database from which they can print specialist maps at virtually any scale. [60] The Ordnance Survey National Grid divides Great Britain into cells 500 km, 100 km, 10 km and 1 km square on a Transverse Mercator grid aligned true north–south along the 2°W meridian. OS map products are based on this grid.
