A report on multiple approaches to the S. Frutuoso of Montélios Chapel survey

Abstract

Approaching one of the goals for this project, the systematization of survey methods and processes supported by low cost digital photogrammetry and 3D laser scanning, case studies are being used to create the bases for a minimum system of survey and documentation of Architectural Heritage. Our focus is defining a reference framework both in the context of Architectural Conservation, directed towards analysis and diagnosis, as well as in the Archaeology of Architecture context, permitting an architectural stratigraphic process of documentation. It is also intended to compare these methods with more classical ones such as topographic surveying and hand surveying. An Information System is also under development, based on a client-server architecture that implements the functions of collecting, processing and storage information, with a web interface. This will allow the management of qualitative and geometric data (plans, sections, elevations, models) to support Conservation and Rehabilitation tasks besides supporting the spreading and study of Architectural Heritage, as well as complementing other existing information systems, exploring possibilities that can be found in between traditional scientific areas. Important discussion about the way to represent a 3D building in a database and to access to its features is being carried out. Ongoing work is based on S. Frutuoso Chapel in Braga.
