CSO Electoral Divisions - National Statistical Boundaries - 2022 - Generalised 100m

EDs are comprised of whole Small Areas. In a small number of cases, CSO EDs do not align with the official boundary, where EDs are amalgamated to ensure statistical confidentiality or where a change was required to ensure better CSO ED/CSO alignment.

Creation of generalised versions of Published ED boundaries. Using Douglas-Peucker algorithm with tolerances of 20m, 50m, 100m and writes out features classes. Uses topology and option of preserving common boundaries to ensure output does not generalise differently on common boundaries.
