Un SIG pour connaître et pour gérer la plaisance dans le Finistère.

Recreational boating is regarded as an asset for economic development in the Département du Finistère, according to its direct incomes. It is seen also as a relevant medium to promote the image of the Département, especially in terms of environment quality and tourism facilities. However, until today this activity has developped without global planning, despite its spreading influence on coastal zone infrastructures and users. While promoting the development of recreational boating in the Département, Nautisme en Finistère, aims at improving its organization and its integration in the local socio-economical and environmental context. Indeed, NEF has ordered and coordinated several complementary studies to increase knowledge in recreational boating and its dedicated infrastructures in the Finistère. The data collected have been integrated into a GIS that provides a consistent frame for the implementation of an observatory dedicated to boating that will be used for the definition of management and development strategies of this thriving activity. This paper deals with presenting this GIS and its first outputs. The diagnosis of the Département capacities and facilities for boating is presented. The GIS potentialities for managing and spreading data about boating, but as well for cross-analysis with socio-economical and environmental data are also described and discussed.
