It is concluded that the precision of these points is attenuated equidistantly as concentric circles. Its center is the weighted average of the coordinates of known points with the radius determined by the precision, the quantity and the distribution of known points. The precision of station points is almost independent of intersection angle, and the precision of known points is almost independent of station point. In some circumstance, the detail points may be more precise.
