What if the coordinate where in feet instead of meters? Where does that
put you? I would also look at local coordinate systems to see what they use.

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.
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
If I start at 0 lat and 0 long, I’m off about 5000KM.
How can I define which sourceCRS to use? How to treat this dataset for further
use?
Thanks for any suggestion.
Joris
