Retrouvez ici la présentation faite par César Ducruet et Justin Berli, Géographie-cités, à l’occasion du 3e congrès international du Groupement d’intérêt scientifique d’Histoire &#38; Sciences de la mer, soutenu par NAOM.WORLDSEASTEMSGlobalization, regionalization, urbanization: an analysis of the worldwide maritime network since the early 18th centuryMapping and modeling maritime flowsWe map for the first time the spatial distribution of about 120 years of vessel flows in a dynamic and interactive manner. The main objective is to provide a pedagogical platform based on geomatics and spatial analysis and statistics to visualize and measure flows at various geographic scales and time periods.Dynamics of macro-structures and world regionalizationWe investigate the changing topological and spatial structure of the global maritime network made of inter-port links with reference to network theory. Special focus is devoted to the impact of various shocks and disruptions (e.g. wars, natural disasters, economic crises, etc.) on the network’s evolution.Co-evolution of urban development and maritime flowsWe examine the co-evolution of maritime flows and urban/regional development and compare the growth trajectories of port and non-port cities based on their situation in the combined sea-land network.Data extractionWe develop a dedicated OCR to extract data on daily ship movements from the registers published in print by Lloyd's.&#160;
