The VertexCreator transformer is useful if the data contains coordinates, but the reader doesn't automatically create geometry.

• A. False
• B. Not applicable
• C. It depends on the data
• D. True

Answer: (D)

VertexCreator turns coordinate attributes into actual geometry when the input data provides coordinates but no geometry is created by the reader. If you have, for example, X and Y fields from a CSV or other tabular source and the reader doesn’t generate points, VertexCreator creates point geometry at those coordinates (and can handle Z if provided). This is especially useful for turning raw coordinate data into usable spatial features that can then be joined into lines or polygons or written out as points. If the data already includes geometry, you wouldn’t need this transformer.
