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.
