START Guide Deutsch Tacheometry : Station centring

[PageContents]
Eccentrially measured sets of polar measurements are computationally transferred to a new centre. You obtain the values, which would have been measured on the centre, optionally including an . If all required values are given, a spatial centring is computed.

Did you know? If the eccentricity (distance centre-eccentre) is small, distances to the remaining targets must be given only approximately.
