A Relative Representation of Trajectories in Geogaphical Spaces

Abstract: The research presented in this paper introduces a relative representation of trajectories in space and time. The objective is to represent space the way it is perceived by a moving observer acting in the environment, and to provide a complementary view to the usual absolute vision of space. Trajectories are characterized from the perception of a moving observer where relative positions and relative velocities are the basic primitives. This allows for a formal identification of elementary trajectory configurati… Show more

“…These works propose studying the sequences of change during the evolution of cadastral parcels [14]. More recently, other models of spatio-temporal reasoning have sought to describe the trajectories of geographical objects in an allocentric [15][16][17] or egocentric vision [18,19]. These models, based on a spatio-temporal mereology, describe, by means of qualitative operators, the relationships that exist between moving objects.…”

“…Ces travaux proposent le suivi de séquences de changement lors de l'évolution de parcelles cadastrales. Plus récemment, d'autres modèles de raisonnement spatio-temporels cherchent à décrire les trajectoires d'objets géographiques dans une vision allocentrique ( Van de Weghe et al 2004, Van de Weghe et al 2006) ou egocentrique (Noyon et al 2006, Noyon et al 2007). Ces modèles, basés sur une méréologie spatio-temporelle, décrivent à l'aide d'opérateurs qualitatifs les relations existant entre objets en mouvement.…”
