Résumé

Into an archaeological GIS, stored information is in spatio-temporal multi-modal form. Dates are estimated according to excavation data. Localizations are determined by several tools such as GPS, radar,... All of these imply some uncertainty, for which fuzzy logic becomes a common use. By representing data by fuzzy number depending on specific modalities, we obtain fuzzy spatio-temporal data. In this paper, we propose to illustrate the interest of fuzzy data representation in archaeology. As Roman streets in Reims usually form segments of lines, we apply the fuzzy Hough transform to those fuzzy multi-modal data to estimate their presence in accordance with given periods. According to experts, we propose to visualize in GIS archaeological data and simulations obtained by merging this fuzzy information. 1
