等高线图等高线高程自动注记算法研究

Study on Arithmetic for Contour Height Automation Annotation in Contour Map

针对现有等高线图等高线高程自动注记算法没有顾及等高线分布的整体性和渐进性的不足,提出了一种新的等高线高程自动注记算法。由于该算法着眼于等高线的整体结构形态,因而与其它算法相比,等高线高程自动注记排列较为整齐、分布较为协调、数量适中。

This article brings forward one kind of the arithmetic for automatic contour annotation in allusion to the insufficiency without considering the integrality and the progress step by step of contour distribution. Because of the arithmetic having respected for integrality structure shape, so the arrangement of height annotation more order, the distribution more harmonious and the amount more mezzo of contour.
