Abstract

The aim of this paper is to describe the principles on which the Caere GIS has been created and to offer an overview of the spatial analyses conducted and the theoretical principles on which they are based. In order to satisfy the ultimate goal of the project, a solution is described for the dissemination of the results across the Internet through GIS technology. Indeed, at the outset of the project, the decision had been taken to create both a GIS application for internal use and a separate dynamic GIS multimedia application for data diffusion across the Internet. Through the GIS platform, thematic maps of the site have been created, exploiting the ability of topological analysis to explore the mutual relationships between structures. The use of the GIS was not restricted solely to this application, as its full potential was exploited through the use of its analytical engine. Several spatial analysis techniques were used (in particular Viewshed analysis) both for the study of the distribution of finds at site level and for the wider analysis of the surrounding territory of Cerveteri. Finally, the on-line publication of the GIS will offer a chance to create a living document, continually reviewed and updated by the author. It will also constitute the first step towards the standardisation of a metalanguage, that will permit effective multimedia communication and the exchange of different data formats and sources.
