This article:

https://docs.safe.com/fme/html/FME_Server_Documentation/AdminGuide/Configuring-Datum-Shifts.htm

explains various methods of configuring FME to work with USA and Canadian grid shift files. However, the company I'm working for routinely works with both USA and Canadian data, so it's not practical to set this value for all of FME.

 

Rather than performing a manual CSMapReproject everywhere it's needed in the workspace, is it possible to define the grid shift file to be used just once for an entire workspace? It would be great if this was available as a setting under Workspace Parameters but there doesn't seem to be anything there....

Hi @nic_ran​ ,

It is currently not possible to set it as a Workspace Parameter. I'd recommend submitting an idea for us to gather interest on this idea.

 

Since the default setting can be overridden in the CSMapReprojector, it is recommended to explicitly set the transformation rather than setting it to "Auto".

 

If you are utilizing FME Server with more than 1 engine, you could have engines on one machine to run jobs using the Canada datum shift files, and on another machine have engines that use the US datum shift files. It would just need to be configured for each of the machines - as outlined in the documentation you linked.
