Abstract
As the accuracy of observed angles and lengths is one of the main factors in the final accuracy of a mapping task, the justification of network also plays a major role here. The justification of network according to the real north is a simple task and has many advantages. If this operation (network justification) is performed through astronomical observations, the mapper must be aware of all sources of error in the justification of network and understand that even if the lengths and angles are accurately measured, the existence of error in justification of network can reduce the final accuracy. In this paper, that source of error is discussed which has not yet received the attention it deserves, and a field approach has been proposed to eliminate this error.
