Title: Transformation between coordinate systems
Post by: AndrejH on May 13, 2021, 03:42:56 PM
Good afternoon!

Mr. Pasumansky I'm kindly asking you to let me know what method is used for transformation between coordinate systems in Metashape? My colleagues and I think that it might not be only a 7 parameter transformation, but some kind of polynomial. Could you please confirm or deny this? Could you please tell me more about the method you use?

Kind regards,
AndrejH

Hello AndrejH,

Metashape is using 7-parameter Helmert transformation in geocentric domain.

Please refer to pages 108-109 of the following document:
