The scanned maps are made available on the site using the following steps:

1. Georeferenced using the [Georeferencer](https://docs.qgis.org/3.34/en/docs/user_manual/working_with_raster/georeferencer.html) plugin for QGIS.

2. Exported to GeoTIFF format.

3. Saved as XYZ tiles using [gdal2tiles](https://gdal.org/en/latest/programs/gdal2tiles.html)

4. Uploaded to an R2 Bucket on Cloudflare.
