Développement d’un outil de géo collaboration au sein d’une collectivité territoriale: l’exemple de l’Atlas historique du Val-d’Oise

The Historic Atlas of Val-d’Oise is a tool with the objective to propose information concerning the evolution of the territory of Val-d’Oise. This application is an important step towards the development of the archaeological GIS project which is now a part of the Val-d’Oise Department project of GIS. The interpretation of the evolution of this project shows us how the archaeological methodologies develop with these tools, and how the informational and the technological foundation gives us the opportunity to develop this online application
