Abstract : Coastal seas are the seat of multiple, sometimes rival, human activities interacting with the natural environment. An understanding of the interactions, between these activities and the environment, is a major objective of research into sustainable developement. In this context, a focus on the ways in which Man uses and exploits the environment is clearly indispensable. Such a focus can reply to important questions posed by scientists through their quest to evaluate the role of human activity in the evolution of ecosystems, and by administrators in search of information which offers a global and interdisciplinary vision of the territory. In this framework, a maritime environment poses specific problems. The legibility of phenomena connected with human activities, in this form of open space, is so much more complex. Therefore a methodology, which aims to analyse the system at work, is proposed. It would involve producing a description of how activities progress in space and time, through the use of spatio-temporal filters. This approach provides the foundation for a conceptual and logical modelling of human usage of the environment, which can be integrated within a simulator of Dynamics of HUman Activities DAHU). The exploitation of results via a GIS allows for the restoration of relevant spatio-temporal representations and thus establishes a useful synthetic form of information for a concerted approach to management of coastal seas.
