Hello,

I have a csv file with a list of coordinates. for example one of
them: X Y 12374462.4355 4877977.8396

notice the (to me at least) strange X coordinate: in the 12millon
range.

This might be a false Easting. In the Soviet Union, 3-degree or 6-degree Gauss-Krueger systems based on the Pulkovo datum were common. To distinguish the zones, a high value of false Easting was added.


I know the point should land somewhere near the Kazach town of
Shalkya, with coordinates in the EPSG3857 (WGS 84 pseudo mercator) of
+/- X: 750800 Y: 5472000

These coordinates end up in the South of France for me.
There might be one digit missing for the Easting.


Greetings,
André Joost
