The Ordnance Survey (OS) has been making maps of Great Britain for more than 200 years. OS products are now stored, produced and used digitally, rather than as printed maps. Hertfordshire County Council have many of these digital products and processes them into a format suitable for the Geographic Information Systems (GIS) used within the council.

OS map data is supplied through The Mapping Services Agreement and used under licence.

All Ordnance Survey data is copyright and it is a legal requirement that an appropriate OS copyright acknowledgement is displayed alongside all copies, whether in digital or hardcopy form. 'Ordnance Survey' is a registered trade mark of Ordnance Survey.
