Abstract

A total station includes a telescope, an EDM unit, and an onboard computer. The telescope is manually adjusted by a user to cause a target to be set at last partially within an FOV of the EDM unit. After the manual adjustment, an optical aiming point associated with the telescope is misaligned from a center point of the target by an offset angle. A user input indicating that the manual adjustment has been performed is received via a user interface. In response to the user input, a slope distance is measured using the EDM unit and an angle associated with the optical aiming point is measured. The offset angle is computed based on the slope distance, and an angle associated with the center point of the target is computed based on the angle associated with the optical aiming point and the offset angle.
