Abstract
The article gives comparative analysis of the creating horizontal and vertical geodetic control network for the purposes of research and building. It is recommended to create geodetic network on the territory up to 1–2 sq km by means of linear-angular measurements with the accuracy of urban fourth-order traverse. After centering the total station and the reflector with an error not more than 1 mm, the minimal network side is 140 m. The precalculation of geodetic control network accuracy with the given confidence level can be performed in CredoDAT. Creation of vertical and horizontal geodetic network should go simultaneously – by means of reciprocal trigonometric leveling of III–IV order accuracy. The height of the total station with use of specific tape measurer Leica can be measured with error of up to 1 mm. The requirements of the acting set of rules «Geodetic works in construction» are not always substantiated and require careful attitude.
