Abstract

V diplomski nalogi smo obravnavali položajno 3D geodetsko mrežo OŠ Polhov Gradec. Opisali smo obliko geodetske mreže, načine stabilizacije in signalizacije točk v mreži. Predstavili smo merski instrumentarij, ki smo ga uporabili pri izmeri mreže in glavne postopke obdelave meritev. Pri izravnavi položajne 3D geodetske mreže, ki smo jo sicer obravnavali posebej v horizontalnem in posebej v višinskem smislu, smo primerjali vpliv različnega števila in geometrije danih točk. V prvem primeru smo geodetski datum definirali z dvema danima točkama 3 in 4, v drugem primeru pa s tremi danimi točkami 3, 4 in 5. Ugotovili smo, da višjo in bolj homogeno natančnost točk dobimo v primeru s tremi danimi točkami, saj so bolje razporejene po celotni mreži. Pri izravnavi višinske/nivelmanske mreže smo obravnavali dva primera. V prvem smo v izravnavo vključili vse meritve nivelmanskih zank, v drugem primeru pa smo izpustili višinsko razliko med reperjema R4 in R2. Ugotovili smo, da v drugem primeru kljub eni povezavi manj ne dobimo bistveno slabše natančnosti višin točk po izravnavi.

Secondary title: Survey of horizontal and height network at elementary school in Polhov Gradec
Secondary abstract: The thesis deals with the 3D geodetic network of the Elementary School of Polhov Gradec. The shape of the geodetic network as well as the stabilization and signalization of the control points is described. The range of measuring instruments used for measuring the network and the main procedures of the measurement-processing are presented. The influence of differing amounts and the geometry of given control-points was compared during the adjustment of the 3D geodetic network. In the first case the geodetic datum is defined with two given points (3 and 4) while in the second it is defined with three given points (3, 4 and 5). The conclusion is that better and more homogenous accuracy of the control points is achieved in the case of three given control points. This is due to the fact that they are more effectively arranged through the entirety of the network. Two instances are considered in the case of the adjustment of the height network. The first one includes all measurements of the levelling loops, while the second ignores the connection between height benchmarks R4 and R2. The conclusion is that there is an insignificant loss of accuracy of point-heights after adjustment of second instance, regardless of one connection less.
