How to use XYZ Tiles for Bion
- Any web server — unpack the archive into the site directory, and the path to the tiles comes out like /tiles/{z}/{x}/{y}.png.
- Leaflet — L.tileLayer('tiles/{z}/{x}/{y}.png', {minZoom: 10, maxZoom: 16}).addTo(map); take the bounds from metadata.json.
- OpenLayers and MapLibre — an XYZ source with the same template; in MapLibre that is a raster source with a tiles field and a tile size of 256.

FAQ: XYZ Tiles for Bion
What tile format?
PNG with transparency by default. JPEG is available for smaller file size.
What zoom levels?
Default zoom 10-16 (city). Configurable from 1 (world) to 19 (individual buildings).
How is this different from MBTiles?
Tiles are individual files in folders (Z/X/Y), MBTiles stores all tiles in a single SQLite file.
How many files will there be?
The number of tiles grows fourfold with every zoom. The range 10-16 over a city means thousands of pictures, while zooms 18-19 will give tens of thousands and a long generation. Pick the top zoom by the real task.
Which projection are the tiles in?
Web Mercator (EPSG:3857) — the slippy map standard, the same one OpenStreetMap and Google use. No additional configuration on the client side is required.
