地形可视化

由于地形可视化有着广阔的应用背景，近来越来越受到人们的关注，该文在给出地形可视化的基本概念和研究内容后，着重讨论和回顾了国内外学者在形形可视化的数字地形模型、地形的简化、地形的多分辨模型和地形的真实性等４个专题领域的主要研究方法和成果，以及尚未解决的问题，最后对这一领域的研究方向和应用前景进行了展望。

Overview of Terrain Visualization

Terrain Visualization has become increasingly interesting in recent years because it has wide application backgrounds. In this paper, we summarize the terrain visualization to four categories in terms of digital terrain model, terrain simplification, multiresolution model and terrain reality. Based on the survey, discussion and comparison of existing methods and results, we formalize the concepts and research contents of terrain visualization. At last, the potential applications of this domain are predicated.
