Theoretical Basis for Adjusting the Principal Condition of the Automatic Levels

Jednadžba geodetske vizurne linije durbina nivelira s kompenzatorom predstavlja osnovu za analizu glavnog uvjeta nivelira. Sadržaj ovog članka služi kao uvod u prikaz različitih terenskih i laboratorijskih metoda određivanja pogreške geodetske vizurne linije, a koje će biti opisane u jednom od sljedećih brojeva ovog lista.The equation of the geodetic line of sight presents the basis for analysing the principal condition of the levels. The subject of this article is theoretical introduction with the purpose to illustrate the various techniques used to determine the error of the line of sight, in the field and in the laboratory, which will be described in one of the future article
