Hi there,
The Coordinate System User Parameter does not allow the user to select Vertical coordinate systems. These are supported in various ways as listed here: https://community.safe.com/s/article/which-transformer-do-i-use-to-do-3d-reprojection-v
I cannot currently use the esri reprojector in an automation and provide user parameters for the input/output vertical and horizontal coordinate systems. I can only select horizontal coordinate systems.
It would be good to be able to have a drop down that lets you filter by type (Vertical/Horizontal) as well as by region similar to how the others work e.g. CS-MAP
Thanks,
Marc
