摘要
从制图综合的约束条件着手,针对等高线的自动综合方法进行研究。提出了等高线综合算法的比较方法,制定出一套等高线综合方法的评价指标并进行了实验,从几何约束、拓扑约束、结构约束等方面验证了这套方法和指标的合理性和可行性。
Based on constrain condition of cartographic generalization, this paper set out to study the generalization methods of contour lines. And then, the paper raised the comparison method of contour lines' generalization algorithm, and formulated a series of evaluation indicators of it, verifying the rationality and feasibility of the method and indicators in geometric constraints aspect, topological constraints aspect, structure constraints aspect by experiments.
