Field Boundary features are coincident with and reference all, or part of, an underlying OS NGD Structure (Built Obstruction) Line. They represent physical barriers between adjoining areas of land. There are five distinct categories to describe Field Boundary features: Tree Canopy, Wooded Strip, Hedge, Wall, and Other. An 'Unknown' description is applied when a feature hasn’t yet been classified.
Field Boundary features are predominately classified across Rural and Moorland areas in Great Britain where they are adjacent to, or contained within, topographic areas of Agricultural Land, Trees, Rough Grassland or Heath, or when they are adjacent to land in the Rural Payment Agency’s (RPA) Rural Land Register (RLR) where they are situated within urban areas in England. Features adjacent to land in the RPA’s RLR are buffered by 2metres.
See the Field Boundary Description Value Code List for Field Boundary feature definitions.
Water-based boundaries (for example, Ditches and Drains) are features within the OS NGD Water Theme and are therefore not categorised as Field Boundary features.
