Based on inclusion exclusion principle of set theory,a new algorithm to calculate the whole projective area was put forward to those overlapped complex geometrical objects in any direction.
在此基础上 ,根据集合论中的包含互斥理论 ,提出了一种求取多个复杂几何形体在任意方向的投影面积的新算法 。

This paper discusses the influence of height varying in the projection surface of terrestrial network when applying results of hugh accuracy positioning by satellite observations to Gauss coordinate system.
由于我国许多矿区平面控制网采用投影面为任意高程面（测区平均高程面或抵偿面）的独立坐标系，当GPS网和地面网在高斯平面坐标系中进行联合平差时，应顾及投影面高程变化时对高斯平面坐标的影响。

In order to transform GPS networks to independent coordinate system strictly, this paper puts forward a new method, by which the regional ellipsoidal surface is more coincidental with the projection surface by means of readjusting orientation of ellipsoid ,the effectiveness of this method has been demonstrated by the application to Ningbo GPS control network.
为使GPS网严格地归算到地方独立坐标系 ,提出了一种使区域性椭球面更密切地吻合于既定投影面的新方法 :先改动已知椭球的长半径和偏心率 ,使椭球面与投影面在位置基准点处相交 ,再对椭球的定向进行调整 ,以消除椭球面相对于投影面的倾斜。
