DISTANCE BASED REASONING WITH QUALITATIVE RELATONS BETWEEN MOVING POINT OBJECTS CONSTRAINED BY NETWORKS
IntroductionAs Hazarika (2005, p.1) stated: Moving around the environment is one of the primary tasks which human beings and animals accomplish equally well. Therefore, it is not surprising that continuously moving objects are prevalent in many domains such as human movement analysis (traffic planning or sports scene analysis) and animal behaviour science Laube et al., 2005. From the geometrical point of view, most applications focus on the positional movement of the object itself, therefore these objects are commonly simplified into points. Recent advances in various positioning technologies (GPS, wireless communication, …) allow capturing and storing large amounts of such moving point objects Laube et al., 2005; Zeimpekis et al., 2003. Research has been done in generating Brinkhoff, 2002; Pfoser and Thcodoridis, 2003), indexing Agarwal et al., 2003; Saltenis et al., 2000, modelling and querying Erwig et al., 1999; Sistla et al., 1997 moving objects in spatiotemporal databases. However, only recently work has been conducted in reasoning about the relations between moving point objects, especially in a qualitative framework Cohn and Renz, 2007; Van de Weghe, 2004. Yet, it is argued that new techniques within information systems, such as Geographical Information Systems (GIS), should increasingly employ qualitative methods Egenhofer and Mark, 1995, in order to come closer to the way information is communicated Renz et al., 2000, since humans prefer to communicate in a qualitative way Freksa, 1992b. In terms of GIS, these ideas completely fit within the scope of Na?ve Geography Egenhofer and Mark 1995. Due to the popularity of these systems, they are not only used by domain specialists (e.g. Google Earth, car navigation systems). Using qualitative methods should ensure information systems to be easily accessible to a large range of users Egenhofer and Mark, 1995.
