In the second half of the previous century, analysis of deformations became a highly interesting subject of research and practical application in industry. The presented approach was developed in ...British Columbia, Canada, for the determination of potential deformations on several dams and landslide areas. Original measurements were obtained via standard surveying observation of distances and directions for horizontal positioning, and elevation differences for vertical positioning. GPS vectors were added some years later. The geodetic measurements of several epochs were adjusted with the parametric model of the method of least squares with minimum datum constraints. The deformation analysis was made with the successive application of the Helmert transformation.
V prispevku je predstavljen predlog za novo oštevilčevanje nivelmanskih poligonov in reperjev. Obravnavana je tudi analiza natančnosti izmerjenih višinskih razlik, opravljena na podlagi odstopanj ...obojestransko merjenih višinskih razlik in odstopanj pri zapiranju nivelmanskih zank. Na podlagi izravnave nivelmanske mreže in nivelmanskih poligonov je analizirana tudi natančnost na podlagi popravkov merjenih višinskih razlik in izvedena ocena natančnosti določitve nadmorske višine reperjev ; This paper presents a proposal for a new numbering of levelling polygons and benchmarks. Furthermore, an accuracy analysis is done with regard to: measured height differences, residuals calculated from differences of the forward and backward runs, residuals from loop closures, and results from network adjustments.
