Abstract

The article analyzes the distortions introduced by the cartographic projection of Gauss. The authors justify that modern high precision measuring instruments should be accompanied by qualitative methods of measurement results processing in the mountainous areas. It is shown that the operation of transfer of the axial meridian should be carried out practically at each object under construction at a distance from the axial meridian by more than 15-20 km. The maximum limits of the work area distance from the axial meridian are determined when performing high-precision geodetic operations on the territories of the area and linear objects. It is grounded that for engineering and geodetic works the three-degree width of the zone is more preferable than the six-degree width of the zone. Errors caused by the influence of geodetic height are analyzed. It is noted that the use of the auxiliary surface of relativity is a prerequisite for modern engineering and geodetic work. We have identified the main factors that distort the strict transition from Cartesian coordinates to the Gaussian coordinate system and then to the surface of the relativity of the object under construction.
