I am reading an Oracle spatial table and writing the content to an ArcGIS Online feature layer (hosted). There are no transformers in between. The shape_area in the ArcGIS Online feature layer is larger than the actual area the object has in Oracle. there is a factor of 2.61 between them.

There seems to be a new area calculation taking place in the writer writing to the ArcGIS Online feature layer that does not seem to be right.

How can I prevent that?

 

Greetings, Hans

hi @fme_hans​ 

I suspect the issue you're seeing is related to the coordinate system defined for the ArcGIS Online feature layer's feature service. Since SHAPE__Area and SHAPE__Length are controlled and updated by ArcGIS Online, you can try setting creating a new feature service with the same coordinate system as the Oracle Spatial table and then writing the data again to see if there is any difference.
