OS (GB) Meridian 2 is a mid-scale vector product, available from www.ordnancesurvey.co.uk OS OpenDataTM. OS (GB) Meridian 2 uses a number of layers of data, including motorways, A roads, B roads, railways, developed land-use areas, hydrology, woodland. Cadcorp SIS 7.1 takes the OS (GB) Meridian 2 Shapefiles and builds topology from them.
Note: OS (GB) Meridian 2 is also available in two other formats:
NTF format - NTF is a nationally agreed standard for the transfer of geographical data. Cadcorp SIS 7.1 will open Meridian 2 NTF files and convert non-topological NTF items to topological items.
DXF format - Meridian 2 DXF conforms to AutoCAD release 12. With Meridian 2 DXF each feature is free-standing with no topological relationship to any other feature and therefore does not support topology.
Scale of 1:50000.
