摘　　要：探讨了图解法界址点坐标改正计算的方法。该方法以实地丈量的界址边长及界址边方位变化最小为约束,进行图解界址点坐标改正计算。实例计算表明,平差后的界址边长与实测值一致,并实现了几何图形保真。除界址点坐标精度难以满足地籍调查解析法要求外,界址边长、界址点相对位置关系、宗地面积均能满足地籍调查解析法需要,具有很好的应用前景。In this paper, we explored graphic boundary point coordinate adjustment method with side and boundary azimuth constraints. In this method, the boundary azimuth should be minimal. The graphic boundary edges adjusted almost equal to the measured values. The graphics made up of edges adjusted had high fidelity. And we can get the parcel area by computing the graphics. Experimental results show that this method is effective, but it also has a drawback.The accuracy of the graphic boundary points can't satisfy the standard of analytical method. In general, the method we explored has practical value.
