等高线图在实际工作中应用非常广泛,在数字地面模型的基础上自动生成等高线图有许多算
法。在数字地面模型的基础上,着重讨论了四边形格网等高线图的自动生成方法,主要包括等高点的判
断、跟踪和连接,为了使等高线跟踪唯一,提出一个新的等高线追踪的判别算法。实践表明在“跟踪—连
接”中确定等高线的走向时,不仅可以避免追踪的不确定性,而且简单实用,所述等高线的“判断—跟踪
—连接”是正确可行的。
- Abstract:
-
Contour map is quite useful in practice .There is much arithmetic in automated generating contour map based on the Digital Elevation
models.In this paper , we focus on discussing a method on the base of DEM, including judging 、tracking and linking of the points of
same altitude .In order to confirm the contour' s uniqueness, the paper introduces a new method of tracking contour .While confirming the
direction of contour in the ”tracking-linking” procedure , the method not only is simply and utility , but also can avoid some uncertain result .
Practice show that the ”judging-tracking-linking” method describled in the paper is correct and practicable .
