Guidance to help people building a government or other public service determine the local authority which an individual property or premises resides.
The guidance was informed by an analysis of addresses in England using a spatialite database which may be explored using the accompanying datasette server and Jupyter notebook.
The following data sources are downloaded by the build process:
- ONS National Statistics Postcode Lookup (ONSNSPL)
- ONS Postcode Directory (ONSPD)
- ONS UPRN Directory (UD)
- OS Code Point Open (codepo)
The proprietary AddressBase dataset, has to be ordered and downloaded manually from the OS data portal:
We recommend working in virtual environment before installing the python dependencies:
$ make init
$ make
Downloading the data and building the database and indexes can take more than an hour on an modern laptop. To just build the guidance and content:
$ make docs
You can explore the data in a browser using datasette:
$ make serve
