Animated representation of uncertainty and fuzziness in Dutch spatial planning maps

This paper concentrates on developing methods to effectively visualize uncertainty and fuzziness in animated representations by various combinations of graphic and dynamic visualization variables, and selecting or developing a method by which the usability of uncertainty and fuzziness displays in spatial planning maps can be evaluated. As a case study, provincial level spatial planning data of Noord-Brabant, the Netherlands were used. A conceptual framework for animated representation of uncertainty and fuzziness in Dutch spatial planning maps was proposed. Subsequently, the animated representations were designed and implemented in a prototype. For the usability study, the prototype was evaluated in a focus group session and a task and questionnaire session. The results show that animated representations can be recommended to make spatial planners better aware of uncertainty and fuzziness in Dutch spatial planning maps than by using current visualizations.
