[PROJ] Affine transformation for engineering crs

[Torill Kjøsnes Gabrielsen]

Hi,



I have an engineering crs that I would like to transform with an affine
transformation.



The transformation for the crs is defined in 9624:

https://epsg.org/coord-operation-method_9624/Affine-parametric-transformation.html



The coordinate transformation parameter values are:

A0 = 82357.457 metres

A1 = 0.304794369

A2 = 0.000015417425

B0 = 28091.324 metres

B1 = -0.000015417425

B2 = 0.304794369



Is there anyone who can help me address which parameters correspond to those
defined in PROJ affine?



A0 = +xoff?

A1 = +s11?

A2 = ?

B0 = +yoff?

B1 = +s22?

B2 = ?



Regards,

Torill Gabrielsen
