In countries where on the tectonic plate movements, one of the distorting effects due to plate movements occurs on national geodetic networks. As a result of distorting effects geodetic networks lose their homogenous characteristics, and discrepancies increase particularly around active fault lines. Furthermore, these fault lines form distinctive borders on the network, and two sides of fault line become apart from each other in line with the plate movements.
These distortions on geodetic networks make geodetic transformation processes much more difficult and complex. In addition to this, transformations between global and national or regional datum are still needed in much case.
However, it does not seem possible to achieve satisfactory results with conventional transformation methods especially in places on tectonic plate movements and/or places with distortions on geodetic basic network such as Turkey. In this article, there are studies particularly towards solution of the problem of continuity for a transformation based on finite element method. Results verified that finite element based methods are enable to ensure continuity.
