Combining Methodological Tools for the Optimum 3d Modelling of Ntua Campus

Abstract

<p><strong>Abstract.</strong> Rapid urbanisation relates to increased space requirements above and below ground and the development of complex structures. This profound need attracted increasing interest for the collection, modelling, management, visualisation and dissemination of 3D objects through various application fields, such as: 3D Cadastre, 3D City Modelling and Building Information Modelling. Contemporary advances in GIS technology, Geo-Web services and computer graphics facilitate the development of such models accompanied by semantic, geometrical and topological information, while the use of international standards enables the communication and interoperability between the systems. The aim of this paper is to combine state-of-the art methodologies and technologies for the development of semantically enriched 3D models for the Campus of the National Technical University of Athens in Greece. The result is a web-based 3D Campus map that integrates these models as Web Services, providing access to management and navigation for the campus area and can also be used for maintenance purposes from the various NTUA Departments. To this end, the database schema has been designed compatible with CityGML, while attention was given to interoperability issues that arise from differently derived 3D models which had to be stored and visualised while retaining their characteristics.</p>

Benefícios e soluções da integração de BIM-FM e gestão de espaços

“…O uso de realidade virtual em celulares aliada a modelos BIM permite a visualização de informações no local correspondente de utilização do celular [24]. O uso de BIM e Sistemas de Informações Geográficas -SIGs em plataformas WEB pode ser útil para usuários de Campus de Universidades para navegar pelos imóveis e traçar rotas de deslocamento [26]. As simulações computacionais podem ajudar no desenvolvimento de cenários com complexidades diferentes, de modo que gerentes, funcionários e usuários dos serviços podem analisar as interações das pessoas e dos espaços físicos [27].…”

A Semantically Enriched and Web-Based 3d Energy Model Visualization and Retrieval for Smart Building Implementation Using Citygml and Dynamizer Ade

“…It should be noted that the commercial solutions for sharing 3D content using the I3S as a data delivery format is the ArcGIS Scene service, which is provided via the ArcGIS server of ESRI. This approach was implemented by Pispidikis et al (2018), combining different 3D modelling methodological tools and techniques to develop a semantically enriched 3D campus model that can be used for navigation and maintenance purposes.…”
