It was a piece of electoral reform legislation that redistributed the seats in the House of Commons, introducing the concept of equally populated constituencies, a concept in the broader global context termed equal apportionment, in an attempt to equalise representation across the UK. It was associated with, but not part of, the Reform Act 1884 .
Ordnance Survey (OS) is a national mapping agency in the United Kingdom which covers the island of Great Britain. It is one of the world’s largest producers of maps. The agency’s name indicates its original military purpose was to map Scotland in the wake of the Jacobite rising of 1745.

Ordnance Survey maps remain in copyright for fifty years after their publication. OS maps sold by Frontispiece Ltd are ‘out of copyright.’
