- KML created by using the Export functionality of Overpass Turbo with the query https://overpass-turbo.eu/s/29rZ
- TODO: switch to GeoJSON
- The Tile Server URL determines the base style. Currently this is set to https://tile.osm.ch/switzerland/{z}/{x}/{y}.png to get the usual Swiss card style. See https://leaflet-extras.github.io/leaflet-providers/preview/ for other options.
- https://leafext.de/extra/listtracks/ is an example on how to add overlays (using Tracks, but in general any GeoJSON can be loaded)
- This probably needs another plugin to insert the snippet (not yet installed): https://wordpress.org/plugins/insert-headers-and-footers/
- https://leafext.de/extra/categories/forum/ lists the extensions and possibilities
- TODO: get all POI into a GeoJSON
- TODO: lookup on how to style markers in GeoJSON. I think this works by adding a separate attribute in the GeoJSON for the POI and then map the attribute value to an icon in the WordPress Leaflet Map using one of the extensions in the extension plugin.
