Construction, Management and Visualization of 3D Models of Large Archeological and Architectural Sites for E-Heritage GIS Systems

摘要

In this paper we present an integrated system developed in order to record, construct, pre-process, manage,udvisualize and visually navigate 3D models reality based of large archeological and architectural sites forudeHeritage GIS systems. The framework integrates structured geometrical and documentary informationudresulting from multiple sources with the aim to enhance the knowledge of those sites within the frame of itsudhistorical evolution and its institutional management in a 3D GIS/DB. The developed applications wereuddesigned for different types of users, with a largely scalable interface, able to support different outputuddevices and to work at different levels of iconicity. The system allows a full comprehension of the buildingsudin their own context, permitting to discover unknown relationships, to evaluate their architectural occupancyudand to quickly access a complex system of information. The framework has been tested in two differentudsystems - designed and developed to satisfy both internal (cataloguing, documentation, preservation,udmanagement of archaeological heritage) and external (communication through the web portal) purposes:udthe first, in Pompeii, developed in order to have a web-based system that uses Open Source software andudcomplies with national and international standards; the second one, a prototype designed to make availableudon the Google Earth platform the complete Palladian corpus documentation implemented by the CISAAP.
