Hi,
i have finished my presenation. Do you have a German WIKI, too?
I will send you a downloadlink with the pdf and a title with short abstract.
Maybe i can translate the abstract to English with a link to German PDF?
Best regards,
Manfred

Hi Manfred,
You're right, in some situations, it maybe useful to set the datum
transformation to be used.
For advanced users, CTS can use alternative datum transformations (ex. a
Bursa-Wolf transformation between two local datum)
and return several possible transformations between two CRSs, but it is
not exposed through the interface.
Practically, in the library, all CRSs are defined with a toWGS84
parameter and by default, CTS uses only the following transformation chain :
CRS1 -> toWGS84 -> WGS84 -> fromWGS84 -> CRS2
