Hi, you can add custom coordinate systems, check out this link: https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Form/Workbench/coordinate_sys_custom_about.htm 

Somewhere in that link is another link to an online tool which can help you create a custom coordinate system using the Esri WKT shown on this page: https://epsg.io/7792. 

Hi 

Thx but i'm still confused, this code is a standard why i have to insert as custom isn't possible to update the epsg db into data interoperability?

Apparently not all coordinatsystems are included, and this is the way to add it.

Hi

I added the EPSG (using the FME online tool) but when I try to select from the coordinate system I’m not able to find it

can you help please ?

thx

Francesco

It seems like you have stored the coordinate system in ...\Documents\FME\CoordinateSystems\CoordinateSystems, can you move the .fme file to the first CoordinateSystems folder? If that doesn't work you can double check if the folder you put it in is a shared folder (tools > FME options > default paths > shared FME folders)

Also, you have to restart FME for the coordinate system to appear in the gallery.

thx !
