Technologies associated with the second-generation of the WorldWide Web enable virtually anyone to share their data, documents, observations, and opinions on the Internet. In less than three years, mapping platforms such as Google Maps have sparked an exponential growth in user-generated geographically referenced content. However, the " serious "(More)
Commonly used GIS combination operators such as Boolean conjunction/disjunction and weighted linear combination can be generalized to the ordered weighted averaging (OWA) family of operators. This multi-criteria evaluation method allows decision-makers to define a decision strategy on a continuum between pessimistic and optimistic strategies. Recently , OWA(More)
Urban and, regional planning are highly complex processes, where many actors petiorm a variety of tasks and interactions. " Collaborative Spatial Decision hkking " is the keyword charactensing the main f~ of Wban and regional planning q Colktboration of several planners and other actors is essential throughout the planning process. q Representations of(More)
Location-based services (LBS) assist people in decision-making during the performance of tasks in space and time. Current LBS support spatial and attribute queries, such as finding the nearest Italian restaurant from the current location of the user, but they are limited in their capacity to evaluate decision alternatives and to consider individual(More)
SUMMARY Collaborative decision-making usually entails argumentation – the exchange of personal views on certain topics, in particular using logical reasoning. Argumentation is often structured into discussions with contributions by individual participants responding to each other. In spatial decision situations, most discussion contributions will contain(More)
According to choice models in economics, consumer choice can be modeled as a two-stage process, starting with the choice of feasible alternatives, called the screening process, followed by compensatory evaluation of the remaining alternatives. Although spatial decision support systems used in various application areas support the screening process by(More)
This paper proposes to use geographic visualization principles in conjunction with multi-criteria evaluation methods to support spatial decision-making. Interactive maps can be combined with analytical tools to explore various settings of multi-criteria evaluation parameters that define different decision-making strategies. In a case study, the analytical(More)
