> Hmm, do you mean the *number* of coordinates or their precision (e.g.
> 1.42798673123 instead of 1.43)?

I meant, for example a coordinate in EPSG:4326 that is [9.3748734,58.7674797],
once converted to EPSG:3857 projection, becomes
[1043606.1331394053,8130299.147556993], or in EPSG:32633 it becomes
[174889.36968223867,6527824.354682916] ...


Thanks again for the tips. I'll go for the UTM formula for small countries. For
bigger countries I'll need to dig on case per case. I'm especially curious
about which one to use for India for example, or China, or Brazil...

If you have some more tips, please post them here so I can keep them for future
reference, even if the bug is closed.

Fixed for Norway in commit
https://invent.kde.org/education/gcompris/-/commit/99eecbb649208bfb2363e86e88d594e000ad9323

I'll do the same for other maps in geo-countries in the coming days.
