This article defends the use of Geographic Information Systems (GIS) for the management, analysis, examination and modelling of the archaeological data concerning the territory. Within this context, we outline some types of analyses that are being carried out with the use of GIS applied to the case of Segeda. Drawing on these and other experiments, we conclude that GIS technologies and their well-established capacity for the integration, analysis and examination of information from different sources constitute a particularly effective tool for the modelling of complex realities such as the one we are concerned with in our project
