This dissertation addresses visual perspectives and decision-making in geospatial uncertainty and fills a gap in current research by presenting three articles in a holistic approach spanning different areas of the field. The first paper in the dissertation presents an overview of the entire field of geospatial uncertainty visualization through the creation of a typology and its visualization - the visual summary. The typology and its visualization were developed and refined based on feedback from other experts in the field, highlights smaller research domains within the entire realm and shows some of the major relationships between them. The overall usefulness of the visual summary can be shown in its ability to be used to summarize both individual papers at a glance as well as summarize the entire field. This visual summary extends current existing approaches to taxonomies by allowing users a quick visual overview of relevant topics in a research area at a glance. The second paper, an introductory article for a special issue on visually-supported reasoning under uncertainty, utilizes the visual summary as shown in paper one to show both the typology and the utility of its graphic representation for quickly summarizing each article within the field as a whole and also showing their unique contributions to the different sub-domains. It also allows for direct comparison between the three articles published in the special issue and visual identification of research topics not covered from the field.The final paper looks at various factors including individual differences and different map characteristics to identify their relationship in making evacuation decisions. This was conducted through an iterative process in which results from the first study informed the two subsequent studies to compose a more synergistic and comprehensive understanding of decision-making under uncertainty for an approaching hurricane. Study one showed that having more certainty in flooding correlated to higher evacuation rates with marginal significance. Participants also paid attention to the flood height category, stating they would choose to evacuate most in the highest flood height zone closest to the ocean and least in the lowest blue flood height zone found farthest from the ocean. Evacuation rates were also higher overall in a mild flood scenario over a more severe scenario. This led to exploring the maps further and finding that by using real data, the mild flood scenario a lower flood height zone was adjacent to the ocean instead of the highest flood height zone, potentially influencing the results. In study two, the maps in the mild flood scenario were redrawn to close the gap in the highest flood zone so that only this zone occurred adjacent to the ocean. The data showed that participants again evacuate more in the higher flood zones and mild flood scenarios. Study three attempted to disentangle how distance to the ocean and the flood height zones impacted decisions. The results revealed that participants chose to evacuate more when closer to the flood source (i.e. ocean), and once farther from the source, they use flood height as a strategy for choosing when to evacuate.

This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.

In many important decisions, people are uncertain or ambiguous concerning the magnitude of the probabilities of events that can affect outcomes. The classic theory of decision making argues that people's decisions should not be affected by whether knowledge of a probability is precise or ambiguous. This chapter presents a descriptive model of how people cope with ambiguous probabilities in decision making. The model predicts that ambiguity matters. 'Decision weights' associated with ambiguous probabilities are assumed to be reached via an anchoring-and-adjustment process in which people anchor on an estimate of the probability and then adjust this as a result of mentally stimulating alternative values of the probability. The mental simulation process is affected by both the amount of ambiguity and whether outcomes are large or small gains and/or losses. One important factor that determines people's attitudes toward ambiguity is the nature of the role they assume in making decisions. Keywords: Decision making, Attitudes(psychology), Ambiguity, Subjective probability, Risk adverse, Roles. (CP).

Information-Gap Decision Theory presents a distinctive new theory of decision-making under severe uncertainty. Applications in engineering design and analysis, project management, economics, strategic planning, social decision making, environmental management, medical decisions, search and evasion problems, risk assessment, and other areas are discussed. Info-gap theory deals with many of the problems and questions of classical decision analysis such as risk assessment, gambling, value of information, trade-off analysis, and preference reversal, but the distinctive character of info-gap uncertainty repeatedly gives rise to new insights and unique decision algorithms. Furthermore, this book deals with many of the difficult interface issues facing the responsible decision maker such as value judgments concerning risk and immunity to failure, as well as philosophical implications of decision under uncertainty. This book is a fresh approach to the age-old problem of deciding responsibly with deficient information. An info-gap is the disparity between what is known and what needs to be known in order to make a well-founded decision. The book begins with a discussion of info-gap models of uncertainty, which provides an innovative approach to the quantification of severe lack of information. This book can be used in advanced undergraduate and graduate courses on decision theory and risk analysis. It is also of interest to practicing decision analysts and to researchers in decision theory and in human decision-making.

Most decisions in life are based on incomplete information and have uncertain consequences. To successfully cope with real-life situations, the nervous system has to estimate, represent and eventually resolve uncertainty at various levels. A common tradeoff in such decisions involves those between the magnitude of the expected rewards and the uncertainty of obtaining the rewards. For instance, a decision maker may choose to forgo the high expected rewards of investing in the stock market and settle instead for the lower expected reward and much less uncertainty of a savings account. Little is known about how different forms of uncertainty, such as risk or ambiguity, are processed and learned about and how they are integrated with expected rewards and individual preferences throughout the decision making process. With this Research Topic we aim to provide a deeper and more detailed understanding of the processes behind decision making under uncertainty.
