基于任意曲线的地面属性区模型建模方法

Arbitrary Curve-Based Methods in Ground Attributive Modelling

介绍了地表属性区建模和综合数字地面模型的基本概念， 提出一种具有高度灵活性的基于自由曲线定义的地面属性区模型的实测同步建模方法及其算法实现原理。还介绍了这种方法在实测建立高等级公路带状数字地面模型中的应用。

The basic concepts of ground attributes and Synthetic Digital Tarrain Model(SDTM) are introduced.An highly adaptable on_site realtime modeling method and on algorithms based arbitrary curves are suggested.The application of this method in high grade highway survey are introduced.
