Abstract:

The importance of quantifying and representing uncertainty in geographic data is well recognized in geography. Many techniques have been developed for representing uncertainty, and there have been many participant-based empirical studies evaluating the effectiveness of specific techniques. Speed and accuracy of response are often typical dependent variables in these empirical studies. However, there is little empirical evidence to suggest that uncertainty visualization influences, or results in, different decisions. Through a human-subjects experiment, this research evaluates whether specific uncertainty visualization methods, including texture and value, influence decisions and a users' confidence in those decisions. The results of this study indicate that uncertainty visualization may effect decisions, but that the degree of influence may be governed by the decision task and not solely by the specific visualization technique used to communicate uncertainty information. The results of this research will support future research into whether the type of decision task should inform the methods for visualizing uncertainty in decision support applications.
