ABSTRACT
As indicated in previous chapters, various uncertainties exist in spatial data and spatial analysis. Some of these uncertainties can be well modeled and some cannot; for example, uncertainty in the form of ambiguity in natural phenomena, and uncertainties governed by human perception and psychology so far cannot be well modeled. Interactive visualization is a form of uncertainty modeling and is particularly useful in cases where uncertainties in spatial data are too complex for common modeling methods. By using this visualization modeling method, the uncertain nature of spatial data and spatial analyses, such as distribution and uncertainty quantity, can be more clearly presented.
