查询词典 radius angle

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.

对测站精度、细部点精度分布规律进行了分析，结果表明：测站精度和细部点精度均呈同心圆向外衰减，圆中心在已知点的加权平均中心上，半径决定于已知点的精度、数量与分布；测站精度与测站的交会角几乎没有关系，细部点精度与测站的位置几乎无关，且可能高于测站精度。
