Third-party notices
Every file under vendor/ is redistributed to each visitor of
this site, so each carries its upstream licence's notice requirement with
it. The texts below are the upstream ones, fetched from each project's own
repository at the version pinned here. They are reproduced verbatim, not
paraphrased or summarised: BSD-3-Clause, Apache-2.0 and MIT each require
that on redistribution.
Libraries
| Vendored file | Project | Version | Licence | Text |
|---|---|---|---|---|
maplibre-gl.js, maplibre-gl-shared.js, maplibre-gl-worker.js, maplibre-gl.css | MapLibre GL JS | 6.11.2 | BSD-3-Clause | maplibre-gl.LICENSE.txt |
pmtiles.js | PMTiles | 4.5.0 | BSD-3-Clause | pmtiles.LICENSE.txt |
h3.js | h3-js | 4.2.1 | Apache-2.0 | h3-js.LICENSE.txt, h3-js.NOTICE.txt |
fflate.js | fflate | 0.8.3 | MIT | fflate.LICENSE.txt |
Apache-2.0 section 4(d) requires the NOTICE file's attribution text to be carried with any derivative distribution, which is why h3-js.NOTICE.txt is served alongside the licence rather than folded into it.
Typeface
| Vendored file | Project | Licence | Text |
|---|---|---|---|
ibm-plex-sans-latin-*.woff2, fonts.css | IBM Plex Sans | SIL Open Font License 1.1 | OFL.txt |
The font's licence text stays one directory up, at vendor/OFL.txt, where the repository has pinned its hash since cycle 2.
Data
The travel times, coastlines and place names come from nine open data sources, each credited with its licence in index.json and under Sources and method on the map itself.
