A hexmap for library services in the UK to use in visualisations and applications
The original version (developed by Libraries Hacked) is available at services.json.
Since then, Open Innovations created an upper tier hexmap, available on their layouts page.
An edited version of that is included at uk-utla-2023.hexjson. The only changes are to change the Northern Ireland local authorities to the single Northern Ireland hexagon. This is because libraries in Northern Ireland are managed at a national level, rather than by local authorities.
