Dear all,
Statement on Mapping of Heritage Assets
English Heritage is reforming the way in which the current separate designation systems of Listing, Scheduling, Protected Wrecks and the two Registers of Parks and Gardens and Battlefields are created, managed and stored.
A new database is being created called the Unified Designation System (UDS), which will contain all the individual designation records and make these available via the online Heritage List for England. Each record will contain both a textual description and a map. The UDS and the Heritage List for England will also contain World Heritage Site records. The UDS and online Heritage List for England are planned to go live in early 2011.
The status of the map is different depending on the type of record that is being viewed on the Heritage List. This will be made clear in the notes accompanying each record.
For all existing listed building entries, the map does not form part of the official record, but has been added later to assist in identification of the location of the site. The majority of listed buildings are identified with a point, but some have been outlined. These shapes were created with the intention of providing greater clarity about what is listed. However, they were not identified to consistent criteria. We feel this information will require re-assessment and updating to consistent standards before it can be included in the new online Heritage List. Therefore all buildings listed prior to the UDS going live will be marked with a point, until they are reviewed.
Scheduled Monuments, Registered Parks and Gardens, Battlefields and World Heritage Sites all have maps as part of their official records and the maps available with the official records in the Heritage List are copies of those maps. Inaccuracies may have arisen in transcribing older hand-prepared maps to digital data based on the latest OS maps. A direct copy of the official map can only be obtained by contacting the National Monuments Record (NMR).
Protected Wrecks are designated using geographic coordinates from which the map is produced. So, again, the map does not officially form part of the record, but is provided as a means of assisting identification.
Even maps that form part of the official record are only part of the evidence of what is protected and are therefore not the only definition of what is designated.
Post ‘go-live’ of the UDS, in early 2011, the mapping of a Listed Building will form part of the listing assessment and will result in a map of a building or buildings that is, or are, the principal listed building. This cannot affect the extent of listing protection, which may go beyond the boundary on the map and include attached or curtilage buildings.
The different asset types will continue to be available as separate datasets via the NMR Data Download Area (http://services.english-heritage.org.uk/NMRDataDownload).
