In 2012 the computation of the transformation parameters between the new International Terrestrial Reference Frame ITRF2005 and the state system of geodetic coordinates 1995 (SK-95) for the territory of the Novosibirsk region was done as a project of SSGA in cooperation with the German authors of the article below.
The software CoPaG was used for the computation of the transformation databases. The whole area was divided into continuous patches, as shown in figure 1. Figure 2 shows the accuracy surface, which could be achieved for the computed transformation parameters in the area.
