Extracting ECW Coordinate System Information

You can use the CoordinateSystemExtractor transformer for that. Downside is that I think it has to read the whole ECW through a reader first.

@juanrodriguezso​,

Can you confirm there's nothing resulting in the attribute _coordsys?

My test ECW file doesn't seem to have a coordinate system so I didn't get a value from the CoordinateSystemExtractor. Can you confirm that your source ECW when opened in a text editor shows the coordinate system information? If so, you could use a TextFile reader to read in your ECW's first few lines to extract that information perhaps?

A late reply, but I've only just started learning FME and only just tackled this very problem.

In my case, the issue with the coordinate system was due to the sidecar files (ers, eww, tab, aux etc.). I found that I was able to extract the correct coordinate system by temporarily putting these files into a new directory and running the work bench on only the ecw files.
