Abstract

A method of stationing an unleveled optical total station includes placing the unleveled optical total station at a first station. At the first station, positions of at least three non-collinear measurement points in an instrument coordinate system are determined using the unleveled optical total station. The method also includes obtaining positions of the at least three non-collinear measurement points in a local coordinate system. A transformation is computed between the instrument coordinate system and the local coordinate system using the positions of the at least three non-collinear measurement points in the instrument coordinate system and the positions of the at least three non-collinear measurement points in the local coordinate system.
