The Great map
If you're like me and you love a map then you should have a look at the Roy Military Survey of Scotland, 1747-1755. The map was commissioned after the Battle of Culloden, when the government realised that they did not have a sufficient understanding of the highlands to crush the lingering Jacobite Rebellion. 
William Roy, the lead surveyor, created the first accurate representation of Scotland, used by those that did not know the land. Earlier maps showed the relative position of features, but were not intend to plan a journey. That required a local guide. Before Roy's map, the government forces were at the mercy of the Jacobites who knew the lie of the land.
This was the start of the Ordnance Survey and the rest is history.
