摘要
提出一种基于不规则三角网(TIN)的等值线生成算法,降低对TIN拓扑关系的要求,具有更广的适用范围。算法简单清晰,避免以往算法起始点选取困难、等值线走向判断复杂的问题。对封闭和非封闭等值线统一处理。
Present a new algorithm of isoline tracing based on TIN, which eases the topological relation requirement of the TIN, so it can be used in more generic cases. Compared to the ad hoc methods, our algorithm skips the searching of initial point phase, and also the judgment of isoline direction. Treat unclosed line in the same way of closed line.
