This dataset was amalgamated, optimised and published by the Spatial Hub. This is an amalgamation of two prior datasets, Conservation Areas and Article 4 Directions, which in many cases overlap equally. These cases are assumed to indicate Conservation Areas with associated Article 4 Directions and the duplicate areas are removed as Article 4 Directions prior to amalgamation of these two datasets.The following quality assurance checks and corrections are carried out on the data: - Polygons are not dissolved/ aggregated by key name and local authority.- The minimum polygon area allowed in the data is 5 square metres- Checks for invalid geometry types- The maximum angle for any spikes is 3 degrees- Any duplicate geometry is removed from the data- Duplicate key names for polygons are not removed- Polygons with no key names are not removed- Checks for basic geometry i.e. self-intersectionPlease contact spatialhub@improvementservice.org.uk for more details.
