projectionEngineFilenames

A list of the Projection Engine files required to support this geographic transformation step. Datum transformations can be mathematically defined (equation-based transformations), or may rely on external supporting files (grid-based transformations). For a grid-based transformation step, this returns a list of the files required to use this transformation, prefixed by an expected subpath of the file(s) underneath TransformationCatalog.projectionEngineDirectory. For an equation-based transformation, this returns an empty list.
