    the GPS/GNSS receiver estimating the position of the GIS data collection device;

    the processor estimating the position of a target object with respect to the GIS data collection device based on data obtained by the laser rangefinder and the pitch and roll sensors;

    the processor drawing on the video display an aiming symbol corresponding to the aiming direction;

    the processor drawing on the video display an augmented reality target marker to mark a measured target object, the target marker appearing to remain fixed to the target object even as the field of view of the camera changes; and

    ,the processor drawing on the video display an augmented reality accuracy marker that shows estimated accuracy of a position measurement of the measured target object.
