Abstract
V diplomski nalogi predstavljamo uporabo RTK-metode izmere pri izračunu volumna nasipa tekom terenske izmere. Za določitev položajev točk smo uporabili instrument Leica Viva GS15, ki vključuje programe za izračun volumna iz diskretnih točk. V dani nalogi smo z namenom ocene napake, ki izhaja iz različno razporejenih diskretnih točk na nasipu, položaje točk določili dvakrat neodvisno. V nadaljevanju smo iste položaje diskretnih točk uporabili za naknadni izračun volumna v programu Surfer, ki vključuje več možnosti interpolacij ploskev in posledično več možnosti za izračun volumna. Cilj je bil ugotoviti, na osnovi katere interpolacije in velikosti mrežne celice poteka izračun volumna z s programom Survey+, ki ga vključuje instrument Leica Viva. Za konkretno delovišče smo ugotovili, da na velikost izračunanega volumna vpliva velikost območja, medtem ko izbira velikosti mrežnih celic na izračun izrazito ne vpliva. Pokazali smo, da izbira različnih interpolacij precej vpliva na izračunano vrednost volumna in da je smiselno izračunati volumen na osnovi dveh neodvisnih vzorcev. Nazadnje smo potrdili, da v programu Survey+ instrumenta Leica Viva poteka izračun volumnov s triangulacijo z linearno interpolacijo ob velikosti mrežnih celic približno centimeter.

Title:Real-time landfill volume computation using GNSS : graduation thesis
Abstract:
The graduation thesis presents the application of RTK-positioning method for calculating the volume of the landfill in real time. At the field work we have used instrument Leica Viva GS15, which includes programs to calculate the volume from discrete points while measuring. The first purpose of the study was to estimate the error resulting from two sets of discrete point positions that were gathered independently. Two independent sets of points’ positions were used to estimate the difference of volume computation due to different spaced discrete points on the landfill. Furthermore, we have used the same positions of discrete points for the subsequent volume calculation in the program Surfer, which includes several interpolations and consequently several options of volume calculation. The objective was to examine which interpolation method and grid-cell size is used for volume calculation in the Leica Viva Survey+ software. For the specific landfill we found out that the volume calculation is strongly affected by the size of the area of the landfill, while the size of the grid distinctly does not affect the final solution. We have shown that various interpolations significant impact the calculated volume, and that it makes sense to calculate the volume from independent samples of discrete points. Finally, we confirmed that the Survey+ program uses triangulation with linear interpolation at the grid about the size of a centimeter.
