Abstract

The aim of this work is to discuss a novel method to access information through an interactive 3D model that has has a connection to places in the real world. This information can be textual (historical, artistic and architectural), photographic (textures, views, plans) and spatial (3D data). The geographical aspects introduce some complexities, but they allow a common and uniform access to the data. The proposed method links information to extended zones of the 3D space and can be used with 3D models that are not subdivided in logical zones, like meshes generated by 3D scanners. The use of an intuitive ranking function lets one find the relevant information by just “looking around”. The possibility to acquire, process and analyse geographic information without the need for installing proprietary GIS software or having deep GIS knowledge has been taken into account in this work, so as to make information more accessible to a larger audience. The method is applied on two case studies: the Napoleone Square in Lucca (Italy) and the crypt of the Cathedral of St. Servatius in Quedlinburg (Sachsen-Anhalt, Germany). In the case in Quedlinburg we wanted to integrate the data produced in the last seven years, during an important investigation and conservation program, that has used extensively GIS format as documentation tool.
