Hi, I need to do my own precise geographic transformation. I use CSMap Reprojector and custom definition in .fme file.

 

I use EUREF transformation to check the accuracy of the results. I enter the parameters according to the following document http://etrs89.ensg.ign.fr/pub/EUREF-TN-1.pdf.

If I try the transformation where the rotation paramets are zero (for example ITRF 2000 to ETRF 2000 in epoch 1989.0), the result is OK. But if I use non-zero rotational parameters. As shown above. The result differs from EUREF.

Does anyone advise me what I'm doing wrong?
