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)
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 multicriteria evaluation method allows decision-makers to define a decision strategy on a continuum between pessimistic and optimistic strategies. Recently, OWA(More)
This paper presents a spatial decision support tool that implements the Ordered Weighted Averaging (OWA) method. OWA is a family of multicriteria evaluation operators characterised by two sets of weights: criterion importance weights and order weights. We propose a highly interactive way of choosing, modifying, and fine-tuning the decision strategy defined(More)
The urban heat island effect is linked to the built environment and threatens human health during extreme heat events. In this study, we analyzed whether characteristic land uses within an urban area are associated with higher or lower surface temperatures, and whether concentrations of ―hot‖ land uses exacerbate this relationship. Zonal statistics on a(More)
This paper gives an overview of Internet Mapping and discusses its use for Geographical Mediation. Internet Mapping summarizes a variety of tools, ranging from geodata and map servers up to online Geographic Information Systems (GIS). First, a classification is proposed, according to the services offered and to the techniques used. Then, the requirements of(More)
In their contributions, participants of spatial planning discussions refer to geographic objects. In this paper, an explicit linkage between online maps and arguments is proposed for being used in a World-Wide Webbased support systems for Collaborative Spatial Decision-Making (CSDM). The representation and storage of geo-referenced arguments in(More)
This paper explores the spatial aspects of GIS-based multi-criteria evaluation. We provide a systematic account of geographically defined decision criteria based on three classes of spatial relations: location, proximity, and direction. We also discuss whether the evaluation score of a decision alternative should be directly influenced by neighbouring(More)
