解析法求算曲边宗地面积

Method of Evaluating Curve Domain Areas by Analytic Solution

在分析解析法求算土地面积的方法及精度的基础上，讨论了用二次插值法室内“加密”曲边宗地界址点，用计算机实现实测界址点与内插界址点，一起高精度地计算曲边宗地面积的方法。

Based on the method and precision of evaluating domain areas by analytic solution,the paper discusses the method of interpolating boundary points of curve domain with quadratic interpolation and the method of precisely evaluating curve domain areas with surveyed boundary points and interpolated boundary points by computers.
