由TIN模型自动生成等高线算法

Contour automatic generation approach based on the model of TIN

简要介绍TIN模型及其数据结构,主要从计算机地图制图的角度,研究基于TIN模型(不规则三角网)的等高线的自动绘制问题。同时,用VB设计程序,通过实验证明其正确性和有效性。

Describes the model of TIN and its data structure briefly. From the perspective of making map by the computer, it studies the question of the contour automatic generation approach based on the model of TIN. At the same time, it designs program by the VB and proves its validity and effectiveness through experiments.
