ANALYSIS OF THE POSITIONING ERRORS IN TIME OF A POINT IN THE TRIANGULATION NETWORK OF THE MUNICIPALITY OF CLUJ-NAPOCA

Abstract

In this paper we wanted to carry out a study of the stability of the Triangulation point of the Turk Tutt, materialized by a ground pilast, due to the escavatiilir made at the base of the slope. The observed trangulation point is among the few points whose signaling pyramid has remained intact, being used in various topographical operations by authorized topographers. Thus, point stability is very important in the accuracy and accuracy of the topographical work that targets this point. In order to track the stability of the point, azimuth and zenithal observations were performed by the reiterated full reverberation method, targeting the triangulation points in the area. The planimetric stability was determined by comparing the known coordinates with the coordinates obtained by performing a multiple cross-junction and altimetric comparison of the resulting elevation by the trigonometric level with the known elevation of the target point. After comparing the coordinates, the values dx = -0,0834, dy = -0,0826, dz = 0,0624 were obtained. On the basis of the values obtained, it can be concluded that the triangulation point of the Turkish Cut is stable and can be used in subsequent topographical observations.
