Vector tiles for the library map project.

The LibraryData database produces a CSV of libraries every night. The LibraryData API also exposes the library locations as GeoJSON. This repository contains scripts that will extract this GeoJSON on a nightly basis and convert it into static vector tiles.

Those vector tiles are then available as Mapbox Vector Tiles for use in web maps.

The process is as follows:

1. Download the latest GeoJSON from the LibraryData API (see download_libraries.py).
2. Use tippecanoe to convert the GeoJSON to a directory of static tiles within the \libraries directory (see generate.sh)

This repository is published as a GitHub pages site, which makes the tiles available in high performance web hosting.

These tiles are made available via GitHub pages and a custom domain. They are available at https://tiles.librarymap.co.uk/libraries/{z}/{x}/{y}.mvt

The tiles are from data compiled by the public and by public library services. They are licensed under the Open Government Licence.
