Paradata to Reuse Holistic HBIM Quality Models in the SCAN-to-HBIM-to-VR Process. The Mausoleum of Cecilia Metella and the Castrum Caetani

Résumé fourni par la source

Abstract The multiplication of efforts to digitize complex architectural and archaeological heritage sites in the form of informative models increasingly requires to document survey and modelling methods through qualitative and quantitative parameters to ensure mutual trustworthiness and proper re-use for different purposes by the potential multiple users, as well as the citation of the contributors’ data source (archaeologists, designers, conservators, civil engineers, geologists, XR-VR developers). The HBIM of the Mausoleum of Cecilia Metella and the Castrum Caetani (Rome, Italy), is part of the digitization of the PAAA (Parco Archeologico dell’Appia Antica, Archaeological Park of the Appian Way): it is emblematic for the complexity of the interconnections among users and contributors across the time. The article discusses needs and definition of Paradata for the re-use of holistic HBIM quality information models documenting the entire SCAN-to-HBIM-to-XR process, through diverse Levels of Development and Levels of Geometry (LODs100-600, LOGs100-600) from the surveys to the modelling phases including Virtual Reality experiences built on informative models, as well as remote environmental risk applications as part of long life management and monitoring. Being the models generated for different HBIM-USES and users, parameters that document the Grade of Accuracy of the Survey and of the Object Models generated in various times are identified. It is the case of the construction technologies associated to the transformation phases for potential future HBIM-uses, as for BIM-to-FEA and Seismic Vulnerability Plan exploitation, remote monitoring or XR (eXtended Reality) in a holistic process.
