Impiego di un Sistema Geografico Informativo per un confronto modellistico preliminare tra due aree archeologiche Sabin¬e

The aim of this work is to contribute to a better understanding of the historical and archaeological heritage. Archaeological and territorial data have been collected and processed in a GIS in order to provide information on the evolution of the population settlement in a selected area used as a case study. The area investigated was that located between the rivers Nera and Aniene (North-South direction) and between the river Tiber and the Sabine Mountains (East-West direction). It is historically identified as the "Sabina Tiberina" region. This area is characterised by a large number of sequential settlements of different populations beginning in the Iron through to the Medieval period. The GIS developed offers the possibility of describing and interpreting the territorial changes caused by the various populations. One of the main features of the GIS is its easy use for non-expert users (such as teachers, students and decision makers). Examples of different types of maps that can be generated by our GIS are presented. Two examples of composite maps containing different types of information (geographical, historical, geological etc.) are presented to show the possibilities afforded by the system.
