A method of determining a position of a point in a local coordinate system using a survey instrument comprising an integrated optical total station and digital level includes measuring an angle associated with the point. The angle may be measured about a vertical axis of the survey instrument, and the vertical axis may be substantially aligned with a local gravity vector. The method also includes determining a distance between the survey instrument and the point using an electronic distance measuring device and measuring a difference in height between a horizontal axis of the survey instrument and the point using a leveling staff positioned relative to the point. The horizontal axis may be substantially orthogonal to the vertical axis. The method also includes determining the position of the point in the local coordinate system using the angle, the distance, and the difference in height.
