1. 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, the method comprising:

  • measuring an angle associated with the point, the angle measured about a vertical axis of the survey instrument, the vertical axis being substantially aligned with a local gravity vector;

    determining a distance between the survey instrument and the point using an electronic distance measuring device;

    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 being substantially orthogonal to the vertical axis; and

    determining the position of the point in the local coordinate system using the angle, the distance, and the difference in height.
