SIGUR: un SIG pour la pratique de l’archéologie en milieu urbain

For cities such as Rennes, that combine a past as an ancient capital city with the status of a modern metropolis, the value of its archaeological patrimony is complicated and complex. In many cases, the poor state of preservation of vestiges is due to the successive occupations and to intense pressure for modern urban development. These factors did not allow for any consideration to preserve its patrimony. Computer technology can contribute to solve some of these problems. First, it is necessary to have a comprehensive knowledge of these vestiges. Then, a spatial analysis would make it possible to create thematic, chronological and spatial connections of the elements that make up the topography. The ability to manage all the scientific information, in its various forms, generated by the archaeological activities on the territory of the city, is essential. The pertinence of the organization of scientific data and the relative specific connection of these to the urban setting not only depends on the quality of the topographic study and urban morphology but also on the potential development. This article presents a dynamic model structure for archaeological information, as well as the application through the development of a Geographical Information System, the SIGUR application. This is a vital step before any online distribution of information to enhance patrimonial value, or before any division of this information, through the creation of collaborative sites to encourage scientific partnerships
