20.500.12556/RUL-124726 The influence of pillar displacements on geodetic measurements This paper deals with the effects that displacements of the measuring pillar have on precise geodetic measurements. The changes in the position of the control points on the object or its surroundings can only be determined with well stabilized and stable reference points. These points are usually stabilized with measuring pillars which are not always constructed in an optimal manner. If they are placed in a dark tube with a high absorption factor, solar heating on one side of the pillar can cause the pillar to deflect considerably due to the temperature difference on the two sides of the pillar. This paper presents the influence of such a displacement, if the pillar is a survey point, orientation point, or control point. We show that even small displacement of the survey point can have important influence on all measurements and that the error in some cases significantly increases, e.g., if the standard deviations of the coordinates of the survey point are 1 mm and their covariance is assumed to be zero, the standard deviation of the distance between measured and exact position of the control point exceeds the value of 2.2 mm. geodesy influence of temperature deflection of the measuring pillar displacement of the measuring pillar control measurements geodezija vpliv temperature deformacija stebra premik stebra kontrolne meritve true false true Angleški jezik Slovenski jezik Članek v reviji 2021-02-12 23:53:01 2021-02-12 23:53:07 2022-09-04 04:01:06 0000-00-00 00:00:00 2020 0 0 15 str. iss. 23, art. 8319 Vol. 10 Dec. 2020 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 528 2076-3417 10.3390/app10238319 41244419 RAZ_Mocnik_Robert_2020.pdf RAZ_Mocnik_Robert_2020.pdf 1 170DAB8E9C06D128F46F4DAE7516D4EE cef2b32aa74d2a9432fa11feaec8247fc65ac53ce980b5a0690b50c867261e4c 6a6043d3-898d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153584 https://www.mdpi.com/2076-3417/10/23/8319 0 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140329 Fakulteta za gradbeništvo in geodezijo 0 0 0
