You may decide that you'd like to modify the style document which is used to
draw the maps in Immich. In addition to visual customization, this also allows
you to pick your own map tile provider instead of the default one. The default
style.json for light theme
and dark theme
can be used as a basis for creating your own style.
There are several sources for already-made style.json map themes, as well as
online generators you can use.
Customizing the map style can be done easily using MapTiler, if you do not want to write an entire JSON document by hand.
