The CRoW Act provides for public access on foot to certain types of land, amends the law relating to public rights of way, increases measures for the management and protection for Sites of Special Scientific Interest (SSSI) and strengthens wildlife enforcement legislation, whilst providing for better management of Areas of Outstanding Natural Beauty (AONB). Open Country 2014 is digitised to OS MasterMap. This data was part of the Countryside and Rights of Way Act 2000 (CroW Act). When using this data to understand the extent of Open Access , it should be used in conjunction with Open land, Open Country, Registered Common Land, Other Statutory Access Land and Other Dedicated Land from the same years. Registered Common Land is a faithful copy of Local Authority commons.
