Boundary-Line provides a representation of the hierarchy of administrative and electoral boundaries and their names for England, Scotland and Wales. Boundary-Line for England and Wales was initially digitised from Ordnance Survey’s boundary record sheets at 1:10 000 scale (or, in some cases, at larger scales).
The Government Statistical Service (GSS) codes are supplied by the Office for National Statistics (ONS) and General Register Office for Scotland (GROS).
Appropriate software is needed to use the data for your intended application.
The high specification of Boundary-Line offers you the following benefits:
Full coverage of Great Britain, supplied as England, Scotland and Wales.
The key boundary dataset for Great Britain, suited to multiple applications using a geographical information system (GIS) and other digital mapping systems.
The full hierarchy of boundaries.
Structured vector format, offering great functionality.
GSS codes, where available, which allow you to link Boundary-Line polygons with GSS information.
Area values for every polygon.
Mean high water (springs) mark, which enables you to build and explicitly identify dry land areas within coastal polygons.
Documented updates via bi-annual releases allow you to easily identify relevant changes.
Unique administrative area identifiers are retained at each update, allowing revised boundaries to be related to your existing data.
Boundary-Line can be used for GIS analysis to support a wide range of business decision-making, such as:
Political analysis
Environmental analysis
Statistical analysis for social or marketing decision-making
Geo-demographic analysis
Asset management
Planning applications
Legal work
