大型彩色地貌晕渲图的自动生成技术研究

Automatic Generation Technology of Large-Scale Colored Hill-Shading

阐述了计算机地貌晕渲的基本原理 ,提出了一个实现地貌晕渲图自动绘制的方案。实践证明 ,该方法能快速、自动地生成大幅面的、满足印刷出版要求和用作专题地理信息系统基础底图的彩色地貌晕渲图 。

This paper expounds the basic principle of the automatic hill-shading, analyzes the advantage and disadvantage between the automatic and the traditional manual hill-shading and presents a scheme of automatic hill-shading. Practices prove that the method can be used to generate fast and automatically large-extent colored hill-shading map, which meets printing and publication and can be used as fundamental background map in thematic GIS, and be applied to the mass production of colored hill-shading map.
