关于分层设色与渐变明暗等深线相结合的地形表示方法研究

Research on Landscape Representation Method by Combination of Hypsometric Layer and Gradient Shading Contour

从传统的明暗等高线法表现地貌的不足入手,提出了基于Tanaka方法粗细和颜色渐变明暗等高线制作方法,并利用ArcGIS平台实现粗细和颜色渐变的明暗等高线自动绘制,将渐变明暗等高线与分层设色叠加。通过对实例的结果进行分析,验证该方法的有效性与可行性;最后,基于上述方法制作出海底地貌图。

This article starts with the performance of the landscape contour method and in this paper,the production methods based on the thickness of the Tanaka method and the color gradient shading contour are proposed,and color gradient shading contour lines can be drawn automatically using ArcGIS platform.Finally,gradient shading contour and hypsometric layer are superimposed.Through the analysis of the instance,we have verified the validity and feasibility of the reform method.
