In addition, the options available for picking should also have the ability to be filtered based on other data. So for example if I pick a point or a polygon in a certain lat/log coordinate first, we should have the ability to filter out coordinate systems that do not apply so we can only pick from relevant ones. There is a precedent for this type of behavior in other software (Autodesk 's AutoCad, AutoCad Architecture and also in Civil 3D) and it works really nicely. In these examples users search by state name (in the decription) and then pick the coordinate system. This can be done in Workbench in the Coordinate System Gallery, but not on FME Server. So for example if I'm looking for a coordinate system for Houston Texas and I search for "Texas" in the parameter dropdown on FME Server, it will not reveal the State Plane coordinate system that I should probably be using (TX83-SC).
