Question

Output data not reading as specified EPSG code

Hi all,

 

I am generating a workspace for a client. A requirement is that output data should be in EPSG:29902.

 

The writers have been defined to use 29902 as the output coordinate system. However, when I open the datasets in QGIS or Arc, the data is reporting as coordinate system EPSG:29903.

 

Is there a way to correct this behaviour? Attached is a simple workbench with a creator transformer and a writer set to use 29902. But the output generated is 29903.

 

Many thanks

Which EPSG code shows the FME Data Inspector? Maybe FME is doing the job OK.

 

Also, check the definition of the EPSG:29903: https://epsg.io/29903

There it says the PESG:29902 was replaced by the EPSG:29903 in 1975.

Hi oscard. Hmm, you are right. FME inspector is showing EPSG:29902 and so is the coordinate system extractor transformer

If the EPSG:29902 is obsolete, that could be the reason QGis shows the other one. According to the definition, both coordinate systems are similar.

You could try this: get two outputs. One with EPSG:29902 and the other one with 29903. Open both of them with FME Data Inspector and compare the coordinates of the same vertex in both outputs.
