Hello Marc,

this is correct, I have a luck and I'm part of Locus Map team .
You are absolutely correct, SQLite + MBT does not by default support other map projections than base Mercator system. In this case, TAR make sense and also because of this (mainly), TAR format is still support for read-only in Locus Map.

So I'll correct my answer before: do not use TAR until you know what you do. Anyway, TAR format will be supported by Locus Map in the future as well.

As I know, mentioned Mapc2maps application is able to reproject maps from one projection to another, so we use it as a solution for some maps we offer in Locus Store as well.

And Swiss maps in application: they use WMTS server for download that already offer EPSG3857 projection, so it's safe so use SQLite as storage.

Hello,
I highly recommend not to use TAR maps. Locus Map still support them (tiles needs to be split to map tiles  + calibration "map" file). Better support is for SQLite based map that may be created by for example mapc2mapc application.

Anyway, I've attached one small TAR maps that should work, to see it's structure.
