摘要
在野外观测地面具有相对最小或最大高程值的点及曲线转向点的高程,构造绘制等高线的非线性数学模型,并考虑适量的地性线点和地貌构造点来绘制等高线。此方法证明比传统方法准确,且外业工作量小。
In the fields, points of maximum and minmum elevations together with points of curvature inflection are chosen and executing levelling nets. A non - linear mathematical model for contouring is established according to three kind of points above. And some special terrestrial points are also considered as references. This method proves to be more rigorous than the conventional methods and also reduces the amount of field work requried.
