I want to compute a centroid for polygons then add the X and Y fields to my features. I could not find any way of doing this in FME desktop as I have it. Can anyone suggest how I might do this please?

Hi,
I think that "CenterOfGravityReplacer" and "CoordinateExtractor" are applicable.
Hi,
maybe "insidepointreplacer" then "pointonareaoverlayer" are better, because centerofgravityreplacer generate the point could be outside of the shape.
Yes. "CenterOfGravityReplacer" may generate a point outside of the original shape. I understood that "centeroid" means the center of gravity which can be outside of the shape. "CenterOfGravityReplacer" and "InsidePointReplacer", which is more suitable differs according to chrismugdan's demand.
Hi,
)
Take your reader,
branch
InsidePointReplacer followed by CoordinatesExtractor
( very fancy to include reprojectors
)Merge with original data
FeatureMerger (The best of feature_ID)
Write Results
Feature-writer
copy attributes from input
add your two X,Y attributes named in the CoordinatesExtractor
Good Luck
