20.500.12556/RUL-181538 Izračun premikov točk geodetske kontrolne mreže na Ljubljanskem barju magistrsko delo Computation of point displacements in the geodetic control network of the Ljubljana Marsh V magistrskem delu obravnavamo analizo premikov geodetske mreže na območju ljubljanskega avto sejma, ki se nahaja na nekdanji deponiji na Ljubljanskem barju. Geodetska mreža osmih točk je bila izmerjena v dveh terminskih epohah, in sicer v letih 2021 in 2024. Uporabili smo kombinacijo klasične geodetske izmere in statične izmere GNSS, kar je omogočilo izvedbo višinske, položajne in prostorske (3D) izravnave geodetske mreže. Obdelava meritev je vključevala redukcijo dolžin, izračun višinskih razlik ter obdelavo GNSS opazovanj s programsko opremo Leica Infinity. Pri vseh vrstah izravnav smo izračunali koordinate točk in pripadajoče natančnosti, rezultate pa uporabili za deformacijsko analizo po metodi Hannover ter za analizo premikov. Metodološko smo analizo premikov izvedli na dveh nivojih: z uporabo izravnanih podatkov klasične geodetske izmere in uporabo izravnanih podatkov statične izmere GNSS. Rezultati analize Hannover in premikov so bili medsebojno primerljivi in kažejo, da se v 3D mreži ni statistično značilno premaknila zgolj točka T5. Najizrazitejši so bili vertikalni premiki, določeni z GNSS izmero, ki so pri posameznih točkah dosegali med 3 in 4 centimetre. Kombinirana metoda je zaznala predvsem lokalne deformacije. This master's thesis examines the displacement analysis of a geodetic network located at the Ljubljana car fair, which lies on a former landfill in the Ljubljana Marsh. The geodetic network, consisting of eight points, was measured in two epochs, in 2021 and 2024. A combination of classical geodetic measurements and static GNSS observations was used, enabling vertical, horizontal, and spatial (3D) network adjustments. Measurement processing included distance reduction, calculation of height differences, and GNSS data processing using Leica Infinity software. For all types of adjustments, point coordinates and their corresponding accuracies were computed, and the results were used for Hannover deformation analysis and displacement assessment. Displacement analysis was carried out on two levels: using combined classical and GNSS data, and using only static GNSS observations. The results of the Hannover analysis and displacement evaluation were comparable and showed that only point T5 remained stable in the 3D network. The most significant were the vertical displacements determined by GNSS, reaching between 3 and 4 centimeters at certain points. The combined method indicated mainly local deformations. magistrska dela geodezija Ljubljansko barje girusna metoda statična izmera izravnava geodetske mreže deformacijska analiza Hannover deformacijska analiza premiki master thesis geodesy jubljana Marsh set of angles static GNSS observations geodetic network adjustment Hannover deformation analysis displacement analysis true false false [S.
