Summary
Proxies for housenumbers calculated for a single street in New Brighton directly from UPRNs. UPRNs containing belonging to the postcodes on this street were simply queries using windows functions to determine if they were sequentally adjacent (defined as with 4 numbers) and then ranked to provide a proxy of housenumber.
This naive algorithm works quite well given that it does not take account of: a)the handedness of housenumber allocation (evens/odds); b) two uprns at the same location (house divided into flats); or c) uprns not in the main sequence located geographically within it. In this case evens & odds have separate postcodes which can be inferred by viewing postcode centroids.
