Crown copyright Ordnance Survey. Type: Antique folding hand coloured survey map, dissected and laid down on linen. The genesis of the Ordnance Survey's original one-inch per mile survey occurred in 1783 when the Royal Societies of Paris and London agreed to connect their two great cities by the use of triangulation to settle the dispute of their relative positions. This triangulation, completed by 1790, together with the outbreak of war with France in 1793, acted as a catalyst for the surveying of England. The survey began in Kent and by the end of the Napoleonic Wars in 1815 most of southern England had been mapped. By 1844, publication of the Old Series, one inch to one mile, was complete for the whole of Great Britain south of Preston and Hull. In spite of concerns about the cost of the survey, work continued until by 1870 the whole of England and Wales had been mapped.
