Coordinate reference system is read wrongly for WFS

Hi there,

 

We have a a problem reading a WFS with FME Workbench 2019.0. (ArcGIS Pro).

 

We're using two datasets, If we check the data in ArcGIS Pro both datasets have overlap and the same coordinate system:

 

When we read the same data in FME using the default coordinate reference system, we see the following:

 

According to the translation log the following happened:

FME Configuration: Using ESRI Reprojection Engine

 

CS-MAP Reprojector: Transformation will be automatically selected for 'LL84' -> 'EPSG:23031', and is not guaranteed to remain the same in future releases of FME

 

Reprojector: Using transformation `ERP50-W_to_WGS84,Inverse(Multiple Regression)' when reprojecting from LL84 to EPSG:23031

 

We tried to use the Reprojector and the EsriReprojector to change the coordinate reference system without success. Also changing the coordinate reference system in the reader itself was not successful.

 

Help or advice would be highly appreciated.

@rumle, Thank you for your advice. We finally managed to solve the issue, turns out the WFS has different versions and the one we were using was projecting the data in the wrong coordinate system.

Use the CoordinateSystemSetter after your readers, to tell FME what the correct Coordinatesystem is. The CoordinateSystemSetter does not reproject the data. It just tells the data what coordinate system they are in, so they show correct.
