Etudes des dynamiques de l’occupation du sol. Questionnements, simplifications et limites

Abstract: Ces dernières années, de nombreux projets ont porté et portent sur l'étude des transformations d'un territoire au cours du temps. Les phénomènes étudiés sont alors constitués de composantes temporelles, spatiales et fonctionnelles. Cette multiplicité des attributs est le coeur d'une certaine complexité. Nous proposons dans cet article d'articuler notre réflexion autour des modèles en partant de la définition du cadre de l'étude pour aller vers l'analyse des transformations, de l'évolution des objets dans une o… Show more

“…the objective of this phase is to start from a time series of vector maps describing a territory through the states of its objects at some given dates to define a data model explicitly providing their life trajectories. Hence, we consider : space as an immutable medium where objects and relationships expressing their spatial configurations are located; time as linear in form and we perceive it qualitatively as being a succession of changes of function, form or topology; and a geographic object as the product of a spatial dimension (S) (the spatial extent of the object), a temporal dimension (T) (ie, the observation date of the object), and a semantic dimension (F) (the function of the object) [5]. Based on these definitions, we consider that the evolution of an object is characterized by the modification of the value of at least one of its components or dimensions.…”

“…Il existe deux (Costa, 2012). C'est pourquoi cette approche domine les SIG historiques, à l'exemple du SIG historique de la ville de Paris (Perret et al, 2015) ou du projet Virtual Kyoto qui reconstitue en 3D l'agglomération nippone en différentes dates clés pour pouvoir spatialiser ensuite des corpus de sources relatifs au patrimoine (Yano et al, 2008).…”
