The Portico of the Church of St. Francis in Urbino: A Digital Map for Monuments

Abstract

This paper describes the preliminary study for restoration works on the portico of the Church of St. Francis in Urbino. The aim of this study is to develop models used for restoration works on the surfaces of the portico, based on a prior architectural survey using different methodologies. The research project was carried out in 2 phases: during the first phase quantitative data were obtained by means of formal-geometric surveys and during the second phase qualitative data were obtained by developing models. Results were diversified according to needs and the methods used in order to create a "digital map of the monument" in its context. In the last phase, the various methodologies were analysed and compared in order to evaluate their accuracy, convenience (in terms of times and costs) and application limits.
