Hi

 

 

Is there an easy way to add a custom transformation with Helmert-parameters to features in FME? Ie A0,A1,B0,B1 - parameters? I have looked through MyCoordSysDefs.fme and articles describing this however it would be nice if there was a Transformer that you could use for this.

Hi! I accidentally sawe this, was hoping that I would get a notification by email when my username was mentioned. The Affiner and 3D-affiner seems to be what you need @jelle

Looks like the 3DAffiner is still the best bet, unless you'd wanted to test out some python like this: https://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.helmert.html

 

Could make for a good hub transformer.
