本文介绍了多种类型不确定性的建模和可视化研究结果——每种不确定性都表现出不同的空间特征。边坡稳定性建模被用作将分类空间数据和连续空间数据中的不确定性结合在一起的工具。讨论了各种静态可视化方法，以及使用交互式动画显示来探索连续表面的多种实现的含义。结果表明，需要仔细定义允许的不确定性及其含义，以校准非专业人士使用的交互式动画。有人认为，这在风险管理决策的情况下尤其如此。 (C) 1997 爱思唯尔科学有限公司。
This paper presents the results of research into the modelling and visualization of multiple types of uncertainty - each exhibiting distinct spatial characteristics. Slope stability modelling is utilized as a vehicle to bring together uncertainties in categorical spatial data and continuous spatial data. A variety of static visualization methods are discussed, as well as the implications of using an interactive animated display to explore multiple realizations of a continuous surface. The results indicate that careful definitions of allowable uncertainty, and the implications thereof, are required to calibrate an interactive animation that will be utilized by non-specialists. It is argued that this holds particularly true in the situation of risk management decisions. (C) 1997 Elsevier Science Ltd.
