摘　　要：以坡度变率、坡向变率、剖面曲率和平面曲率4个坡面因子为例,从计算公式和总体流程角度探讨了可视化自增强方法。通过基于ArcEngine的组件接口技术开发,完成了提取坡面因子、生成晕渲图和融合显示,实现了集准确性、可测量性、直观性和灵活性于一体的DEM地形可视化自增强技术。This paper focused on how to realize self-enhancement technology of DEM with slope of slope, slope of aspect, curvature of profile and curvature of plan by formulas and process. The process, which was divided into extracting factors, generating shading map and merging display, had been developed by Arc Engine component interfaces and interface controls. The self-enhancement technology of DEM topographic visualization which is accurate, measurable, visualized and l exible has been successfully achieved.
