Možnosti eliminácie vplyvu vertikálnej refrakcie pri trigonometrických meraniach prevýšení

Abstract eng:
Refraction can be regarded as a major source of systematic errors which affects on the reliability and accuracy of surveying measurements. Submitted article presents in the first part basic principles of vertical refraction and in the second part brief view and description of existing methods for the elimination of the vertical refraction on the trigonometrically measured elevations. Except classical approaches i.e. height network adjustment with unknown refraction coefficients or reciprocal zenith angle measurement the attention is also given to relatively new methods. Two approaches based on the atmospheric turbulence and two colours method are introduced.
