I use the NZTM coordinate system in my file geodb
I have a workbench extracting me the center of polygans. The extracted values are in meters.
Can someone tell me how to change the coordinates in degree decimal format?
Equivalent to the ArcMap, calculate geometry center -> X coord specifying units as degree decimal
To my knowledge- the attributeReporjector is used to change the projection.
The projection should still be NZTM, I just need the units to change from "metres" to "Decimal degrees". Can I still use the "attributeReprojector" and what parameters need to be supplied to change from NZTM(metres) to NZTM(decimal degrees)?

You'll still be using the NZGD2000 datum and GRS1980 ellipsoid.
I tried the attributeReprojector but I don't get the same values as in ArcMap
Are you sure it's EPSG:2193 to EPSG:4167 in FME?
some sample values attached

+37If your values are different between arcmap and FME, is it actually a question of projection, or is the "center point" different.
FME has 3 different modes for extracting the center point of a polygon
Center of the Bounding Box
Center of Gravity
Closest point to one of the above that falls inside the polygon.
As far as I am aware the ArcGIS Centroid is the center of Mass, whereas the default FME CenterPointExtractor is the center of the bounding box.
