Dépasser la méthode de moindre coût pour mesurer l'accessibilité. Exemple de l'étude des réseaux d'échange préhistorique de l'obsidienne du Moyen-Orient

Abstract : Identifying exchange networks, often through the study of raw materials or skill diffusion, needs an efficient reconstruction of past human movements. Movements are done through physical landscape, the main issue for the geographer is therefore to reconstruct relevant pathways and a relevant network. Obsidian sourcing enables a precise identification of geological outcrops and is a useful method to understand raw materials and lithic skills diffusion. We present an exchanges analysis of obsidian materials and artefacts during the Neolithic and Bronze Age from Anatolian geological sources to the archaeological sites throughout the Middle East. Obsidian movements show evidence of these exchanges and human mobility, but also of an early structuration of this territory with archaeological sites and circulation routes. These routes can be highlighted with GIS technologies like cost surface analysis (cost-distance, shortest path) and flow analysis (current and centrality maps).
