A similarity-based transformation has been routinely applied in various fields of geosciences
with the main purpose of integrating spatial information across different reference frames …

Transformations between local datums/frames have provided an indispensable method for
expressing coordinates in the same datum. The advent of space-based geodetic techniques …

In modern geodesy, there are cases in which the target frame is unique and there is more
