To reduce health disparities and ensure that everyone has access to the healthcare they require, the NHS London Healthy Urban Development Unit (NHS HUDU) maximizes the opportunities that arise from coordinating housing development planning and health programs in London. NHS HUDU intended to use address data to match existing addresses to their Unique Property Reference Numbers (UPRNs), transfer the records onto an online GIS platform (ESRI ArcGIS Online), and keep those records up to date in a SQL database.
