Analiza deformacij s helmertovo transformacijo : Deformation analysis with the helmert transformation

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 drugi polovici prej njega stoletja je analiza deformacij postala zelo zanimiva tema raziskovanja in prakti ne uporabe v industriji. Predstavljeni pristop obravnave deformacij je bil razvit v kanadski provinci Britanska Kolumbija. Z njim smo eleli dolo iti potencialne deformacije na nekaj vodnih pregradah in plazovitih obmo jih na tem obmo ju. Prvotna opazovanja so bila standardna geodetska opazovanja dol in in smeri za horizontalni polo aj in vi inske razlike za vi insko predstavitev. Nekaj let pozneje so bili dodani vektorji GPS. Geodetska opazovanj v razli nih epohah so bila izravnana s posredno izravnavo po metodi najmanj ih kvadratov na podlagi minimalnega tevila vezi med neznankami. Deformacijska analiza je bila izvedena iterativno z uporabo Helmertove transformacije.
