Calibration of Electro-Optical Distance Meters,correction is determined for a particular instrument-reflector combination. All distance-dependent and the constant terms require re-evaluation when using the distance meter with another type of reflector.

,Psychische Störungen: Zahlen und Fakten,ter vapour, carbon dioxide and ozone. Figure 5.1 depicts the transmittance of atmosphere as a function of wavelength for a part of the visible and near-infrared (NIR) spectrum under specific conditions. The figure shows that only a limited part of the NIR spectrum is suitable for EDM.

Miscellaneous Corrections, Computations and Numerical Examples,d slope distance) measurements and the centring of measured zenith angles and slope distances from satellite stations to their respective centre stations. This section then concludes with fully worked examples for the reduction to the spheroid of the measurements of a short and a long EDM line.

Geometrical Corrections,bsequently processed in a three-dimensional network adjustment, it has to be reduced to the equivalent spheroidal distance on a geodetic reference surface, for example the Australian Geodetic Datum. Selected methods of reduction to the spheroid will now be reviewed, prior to a discussion of addition

Miscellaneous Corrections, Computations and Numerical Examples,y paths which were assumed during the derivation of the geometrical corrections in Sect. 7. A number of approaches to the problem are discussed below. These derivations are followed by the discussion of three EDM-related computational problems, namely the computation of height differences from measu
