Following extensive work with our customers and stakeholders, we are releasing our National Polygon and Title Descriptor datasets today.
The two chargeable datasets, combined with Unique Property Reference Number (UPRN) data from GeoPlace, make up our National Polygon Service.
For the first time, customers will be able to download, host and interrogate the complete set of polygons and detailed title information, within their geographic information systems (GIS). This provides business opportunities for new product and services.
The National Polygon Service includes three datasets.
National Polygon dataset
The National Polygon dataset is one of our largest and most popular datasets. With information on more than 24 million titles and 28 million polygons, it covers all registered titles (freehold and leasehold) in England and Wales and shows the indicative shape and position of each boundary.
Title Descriptor dataset
The Title Descriptor dataset provides a freehold and/or leasehold label against each title and then you can view the ‘Class of Title’ and ‘Estates and Interests in land’ information. This dataset is currently only available as part of the National Polygon Service.
Title Number and Unique Property Reference Number (UPRN) Look Up dataset
A Title Number and UPRN Look Up dataset is associated with each title number, where it can be matched. UPRNs are a unique twelve-digit number assigned to every unit of land and property recorded by local government. They were created by GeoPlace, as a joint venture between the Local Government Group and Ordnance Survey. When cross-referenced with title numbers these provide a way of matching files with merged data from other government agencies.
We will continue to use your feedback to develop the dataset attributes, delivery options and update frequency.
