The creation of the Irish Ordnance | The major source of Irish topographical maps in the 19th century is the Ordnance Survey, which covered all of England, Scotland, Wales, and Ireland. The creation of the Irish Ordnance Survey maps was commenced in 1829 and completed in 1858 producing 205 sheets and an index in a series of 1 inch, 6 inches, and 25 inches to the mile. The series has been revised and published at different times. Ordnance Survey maps of greater detail (up to 10 feet to the mile) have been produced for most Irish cities. The significance of the Ordnance Survey Maps cannot be overstated. It was the first complete survey of Ireland since William Petty's survey in the 17th century (1657) to create ''Hiberniae Delineatio,'' the first atlas of Ireland. | ||
