This dataset (published in EPSG:4326 - WGS84) provides polygon data for local authority Green Belt boundaries. Local authorities digitise areas of land designated as Green Belt and send the Green Belt boundaries to DLUHC. The local authority Green Belt boundaries are merged and quality assured by DLUHC and are mapped against OS and ONS Local Authority District (Mean High Water mark) boundaries for the corresponding period. This improves the data quality, removing overlaps between Local Authority Green Belt boundaries and provides consistent approach to area calculations and in the delimiting of land designated as Green Belt where it meets coastal or estuarine areas.
