Tackling the information gap : Comprehensive scientific documentation of virtual reconstructions

Abstract

This contribution discusses virtual reconstruction activities focused on destroyed sacral buildings and their historical context. The research work has expanded far beyond the initial project of reconstructing a vanished synagogue in the City of Vienna (Austria). The development and implementation of conventions for modelling and documentation became essential as the number of reconstruction projects grew. The research primarily focuses on (public) buildings from the 19th and 20th centuries, utilising planning documents, historical photographs, paintings, and comparable buildings for reference. The accuracy of virtual reconstructions varies based on available artefacts and archival material. The scope has expanded to include historical railway stations, and interdisciplinary collaboration supports the ongoing research work. This chapter emphasises the importance of documented research, the challenges of accessing and interpreting archival materials, and the advantages and limitations of computer-aided modelling. The long- term preservation of model data, software compatibility, and the management of uncertainties and information gaps are critical considerations in virtual reconstruction projects. The innovative aspects of this research lie in its continuous long-term focus, comprehensive documentation, and the use of digital tools to communicate historical buildings effectively.
