1824, The Ordnance Survey began mapping Ireland, under the leadership of Major General Thomas F Colby, but ran into a major problem. Persistent mists,which unlike in Britain did not clear by mid-morning. Thomas Drummond solved the problem with a �pea-light�, a pellet of lime (calcium oxide) which burnt with an intense light that could be seen at a long distance through fog or drizzle. This gave rise to the term �limelight�. The triangulation began on the shores of Lough Foyle, which was close enough to Scotland to facilitate a continuation of the triangulation from there.

On this day a payment of �373, 14 shillings was made to Jesse Ramsden for the construction of a �great theodolite�, 3 feet in diameter and weighing 200 pounds (90 kilogrammes) for the purpose of making precise military maps of Britain. The need for this had been foreseen in 1763 by William Roy, amidst fears of invasion from France and a lack of reliable maps for the military. In 1765 William Roy (died 1790) was appointed to survey all of Britain�s coastal areas. By 1784 UK-France relations had improved and cross-Channel efforts were being made to establish the longitude and latitude of Greenwich and Paris. In 1800 the first cartographical unit of the British Army, the Corps of Royal Military Draughtsmen, was formed, based at the Tower of London.

1747, Following the Jacobite Rebellions in Scotland of 1745, the British Government saw the need for an accurate map of the whole of Scotland, not just of the great castles fortresses and estates as existed then. Under the leadership of Lieutenant-Colonel David Watson, General William Roy began a survey of all Scotland. This was completed in 1755, at a scale of 1000 yards to an inch (1:36,000).
