Abstract
A method for determining the Helmert matching parameters for converting the coordinates of points from the common terrestrial to the reference coordinate system has developed. The tech-nique is based on the maximum alignment of the surfaces of the common terrestrial and reference el-lipsoids within a certain local territory and does not imply knowledge of the heights of the quasigeoid. The radius of the local area is limited by a given methodological error in the transformation of coordi-nates from general terrestrial system to Gauss-Kruger projection. For a methodical error of ±2–3 cm, the radius of the local area is about 200 km. Two options for determining the Helmert matching parameters for the fourth three-degree zone of the MSC of the Novosibirsk region are given: according to the reconstructed coordinates and heights of the SDGN, and according to the catalog coordinates and heights of the SGN points located in the same territory.
