CoordinateFetcher

From Fmepedia

CoordinateFetcher is a Workbench Transformer.

The CoordinateFetcher retrieves the coordinates of the n-th point in the object and stores them in the specified attributes. If the object is 2D, the Z attribute will be filled with the default Z value.

An index of 0 means that the first point of the object will be fetched, an index of 1 fetches the second point, and so on. An index of -1 fetches the last point of the object.

If you are only interested in the Z-value, you can try the ElevationExtractor instead.
