Specifying Source Information
Open the Set Translation Parameters dialog.
Note: If you decide to choose another dataset in a different format, you will have to manually select the new format.
Reader Parameters
Reader Parameter boxes allow you to specify additional information relating to some source datasets. When you select one of these formats, the Parameters button will become available. When you click the button, you’ll see a dialog that contains options specific to the format you selected.
If the format doesn’t support any special settings, then the button will remain dimmed (and unavailable).
Note: You don’t have to change the settings if your source format supports this feature – FME will simply use the default settings.
Help for Parameters: When you open a settings box, press the F1 key for detailed help.
Coordinate System
This field will usually display Read from source, which means that FME will simply use default values. In most cases, the default value is all you'll need to perform the translation.
