基于熵的彩色晕渲图设色方案辅助设计

Color Design of the Hill-Shading Map Based on Entropy

在熵理论和地图分级评价模型的基础上,提出了基于熵的彩色晕渲图设色方案辅助设计方法,并进行了晕渲制图实验。从客观信息量测定和主观评价结果的分析表明,本文方法制作的晕渲图色彩过渡自然,地形区分明显,层次清晰,能更好地表达地貌形态。

The paper analyzes the limitation of color design in hill-shading map, and provides a new method for color design based on the entropy and the evaluation model of elevation data classification. With these methods the paper make some experiments on landforms hillshading, and estimate hill-shading map in objective and subjective aspects. The result indicates the representation of hill-shading map is elegant, stereoscopic and colorful.
