BIM AUTOMATION: ADVANCED MODELING GENERATIVE PROCESS for COMPLEX STRUCTURES

The new paradigm of the complexity of modern and historic structures, which are characterised by complex forms, morphological and typological variables, is one of the greatest challenges for building information modelling (BIM). Generation of complex parametric models needs new scientific knowledge concerning new digital technologies. These elements are helpful to store a vast quantity of information during the life cycle of buildings (LCB). The latest developments of parametric applications do not provide advanced tools, resulting in time-consuming work for the generation of models. This paper presents a method capable of processing and creating complex parametric Building Information Models (BIM) with Non-Uniform to NURBS) with multiple levels of details (Mixed and ReverseLoD) based on accurate 3D photogrammetric and laser scanning surveys. Complex 3D elements are converted into parametric BIM software and finite element applications (BIM to FEA) using specific exchange formats and new modelling tools. The proposed approach has been applied to different case studies: the BIM of modern structure for the courtyard of West Block on Parliament Hill in Ottawa (Ontario) and the BIM of Masegra Castel in Sondrio (Italy), encouraging the dissemination and interaction of scientific results without losing information during the generative process

Georeferencing accuracy analysis of a single worldview-3 image collected over Milan

The use of rational functions has become a standard for very high-resolution satellite imagery (VHRSI). On the other hand, the overall geolocalization accuracy via direct georeferencing from on board navigation components is much worse than image ground sampling distance (predicted < 3.5 m CE90 for WorldView-3, whereas GSD = 0.31 m for panchromatic images at nadir). This paper presents the georeferencing accuracy results obtained from a single WorldView-3 image processed with a bias compensated RPC camera model. Orientation results for an image collected over Milan are illustrated and discussed for both direct and indirect georeferencing strategies as well as different bias correction parameters estimated from a set of ground control points. Results highlight that the use of a correction based on two shift parameters is optimal for the considered dataset

Museos virtuales y entorno construido: narrativas y experiencias inmersivas vía centros de geodatos multitemporales

[EN] Our built environment is nowadays considered as a dynamic complex, stretching and transforming across space and time, with the interaction of human, social and economic dimensions. It needs to be safeguarded as living places for the future taking into account such complexity. The general aim of this work is to contribute to the comprehension of landscape values, enhancing participation processes by tourists and local communities, considering the built environment as a system: the sum of natural transformation, ancient artefacts stratification and human activities, partially covering the tangible traces, and functioning as a vehicle for the comprehension of intangible values. Multi-temporal, multi-scale and geospatial datasets can play an important role in such knowledge transfer processes by means of narratives and immersive experiences in a multimedia museum approach. In particular, the cartographic heritage, in the form of metric and non-metric maps, can be progressively used as a source of information for innovative narratives. Virtual Museums (VMs)are additional "channels" to disseminate content and to provide knowledge about cultural heritage; they have emerged from the crossbreeding process between museums and digital technologies. Investigating how digital storytelling may support communication and understanding of complex systems, such as the built environment and landscape, it is relevant because cultural awareness may foster the sense of belonging and identity construction of which Europe is thirsty, contributing to the safeguarding of fragile sites. The paper provides useful information for museums that would like to follow this pathway. It retraces the main steps of storytelling production and presents interesting examples of immersive narrative models based on geospatial data and a virtual hub, helping people to retrieve and access information and to recognize places of memory mostly unknown. Moreover, it offers an evaluation of existing tools that can be adopted for this purpose. Eventually, by virtue of the research carried out for the case study of the Virtual Museum of Como Lake Landscape, the paper aims at ascertaining which kind of stories and experiences can be designed, the potential of these tools and possible weaknesses or constraints that deserve future researches.[ES] El entorno construido se considera hoy en día como un complejo dinámico, que se extiende y transforma a través del espacio y el tiempo, con interacción de dimensiones humanas, sociales y económicas. Debe salvaguardarse como lugares donde vivir el futuro teniendo en cuenta tal complejidad. El objetivo general de este trabajo es contribuir a la comprensión de los valores paisajísticos, potenciando los procesos de participación de los turistas y de los autóctonos, considerando el entorno construido como un sistema: suma de la transformación natural, de la estratificación de artefactos antiguos y de actividades humanas, cubriendo parcialmente los rastros tangibles, y vehículo de comprensión de valores intangibles. Los conjuntos de datos multitemporales, a multi-escala y geoespaciales pueden desempeñar un papel importante en dicho proceso de transferencia de conocimiento a través de narrativas y experiencias inmersivas en el enfoque de un museo multimedia. En particular, el patrimonio cartográfico, en forma de mapas métricos y mapas no métricos, puede utilizarse progresivamente como fuente de información para narrativas innovadoras. Los Museos Virtuales (VM) son “canales” adicionales que permiten difundir contenido y proporcionar conocimiento sobre el patrimonio cultural; surgen del proceso de mestizaje entre museos y tecnologías digitales. Investigar cómo la narración digital puede apoyar la comunicación y la comprensión de sistemas complejos, como el entorno construido y el paisaje, es relevante porque la conciencia cultural puede fomentar el sentido de pertenencia y la construcción de identidad de los que Europa tiene sed, contribuyendo a la protección de sitios frágiles. El artículo proporciona información útil para los museos que deseen seguir este camino. Describe los principales pasos que deberían considerarse a la hora de producir narrativas y pone ejemplos interesantes de modelos narrativos inmersivos basados en datos geoespaciales y centros virtuales, que ayudan a las personas a recuperar y acceder a información, y a reconocer lugares desconocidos o vagamente retenidos en la memoria. Además, ofrece una evaluación de las herramientas existentes que se pueden adoptar con este propósito. El objetivo es aclarar, finalmente, en virtud dela investigación desarrollada en el caso de estudio del Museo Virtual del Paisaje del Lago di Como, qué tipo de historias y experiencias se pueden diseñar, el potencial de estas herramientas y las posibles debilidades o limitaciones que merecen futuras investigaciones.We thank Stefano Della Torre (Head of Polimi dABC) as Sc.

A virtual Hub brokering approach for integration of historical and modern maps

Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and their restricted interoperability limit a wide utilization of available geo-data. This paper aims to describe some actions performed to assure interoperability between data, in particular spatial and geographic data, gathered from different data providers, with different features and referring to different historical periods. The article summarizes and exemplifies how, starting from projects of historical map digitizing and Historical GIS implementation, respectively for the Lombardy and for the city of Parma, the interoperability is possible in the framework of the ENERGIC OD project. The European project ENERGIC OD, thanks to a specific component - the virtual hub - based on a brokering framework, copes with the previous listed problems and allows the interoperability between different data sources

Extended reality and informative models for the architectural heritage: from scan-to-BIM process to virtual and augmented reality

[EN] The dissemination of the tangible and intangible values of heritage building represents one of the most important objectives in the field of Digital Cultural Heritage (DCH). In recent years, different studies and research applied to heritage monuments have shown how it is possible to improve the awareness of the architectural heritage through the integration of latest developments in the field of 3D survey, 3D modelling, Building Information Modeling (BIM) and eXtended Reality (XR). On the other hand, this digital workflow requires a huge amount of data sources and a holistic approach to reach a high level of information sharing coming from different disciplines and sectors such as restoration, geomatics, 3D virtual museums and serious gaming. In conjunction with entertainment software and gaming, this research shows the main results obtained during the generative process of digital environments oriented to improve the level of information and to enrich the contents coming from the informative models. The case study is represented by one of the most important Lombard monuments: the Basilica of Sant’Ambrogio in Milan. This study, starting from the 3D survey and the data collection of the historical records of the church, improves the creation of an XR experience that reaches a new level of interactivity for different types of devices (desktop, mobile, VR headset) and users (experts, non-experts).Highlights:Generative modelling requirements and novel grades of generations (GOG) and accuracy (GOA) are presented in order to improve the digitisation of built heritage from the 3D survey, reducing time and costs of the scan-to-BIM process.The holistic value of generative modelling allows experts to create digital worlds able to faithfully and accurately represent the detected reality and improve new immersive environments for Virtual Reality (VR) and Augmented Reality (AR) projects.Immersive environments are created with a mixture of the latest generation software and hardware, allowing users to discover the hidden historical values of built heritage with new levels of interactivity and information.[ES] La divulgación de los valores tangibles e intangibles en el patrimonio construido representan uno de los objetivos más importantes en el campo del Patrimonio Cultural Digital (DCH). En los últimos años, diferentes estudios han demostrado la posibilidad de mejorar el conocimiento de nuestro patrimonio construido a través de la integración de los últimos desarrollos en el campo del levantamiento topográfico 3D, modelado 3D, Modelado de Información de la Construcción (BIM) y Realidad eXtendida (RX). Del mismo modo, se ha comprobado que este flujo de trabajo requiere de una gran cantidad de datos y un enfoque holístico con el fin de alcanzar un nivel alto de información compartida entre las diferentes disciplinas y sectores involucrados, como por ejemplo, la restauración, la geomática, los museos virtuales 3D y la industria del videojuego. Junto con el software de entretenimiento y los videojuegos, esta investigación muestra los principales resultados obtenidos durante el proceso de generación de entornos digitales orientados a mejorar el nivel de información y el contenido de uno de los monumentos más importantes en Lombardía: la Basílica de Sant’Ambrogio en Milán. Este estudio, que se inicia con el levantamiento 3D y la toma de datos provenientes de los registros históricos de la iglesia, está orientado a mejorar la creación de una experiencia de realidad extendida, con el objetivo de alcanzar varios niveles de interactividad a través de diferentes dispositivos (escritorio, móvil, auriculares de realidad virtual) y usuarios (expertos, no-expertos).Banfi, F.; Brumana, R.; Stanga, C.

A N-D VIRTUAL NOTEBOOK ABOUT THE BASILICA OF S. AMBROGIO IN MILAN: INFORMATION MODELING FOR THE COMMUNICATION OF HISTORICAL PHASES SUBTRACTION PROCESS

This essay describes the combination of 3D solutions and software techniques with traditional studies and researches in order to achieve an integrated digital documentation between performed surveys, collected data, and historical research. The approach of this study is based on the comparison of survey data with historical research, and interpretations deduced from a data cross-check between the two mentioned sources. The case study is the Basilica of S. Ambrogio in Milan, one of the greatest monuments in the city, a pillar of the Christianity and of the History of Architecture. It is characterized by a complex stratification of phases of restoration and transformation. Rediscovering the great richness of the traditional architectural notebook, which collected surveys and data, this research aims to realize a virtual notebook, based on a 3D model that supports the dissemination of the collected information. It can potentially be understandable and accessible by anyone through the development of a mobile app. The 3D model was used to explore the different historical phases, starting from the recent layers to the oldest ones, through a virtual subtraction process, following the methods of Archaeology of Architecture. Its components can be imported into parametric software and recognized both in their morphological and typological aspects. It is based on the concept of LoD and ReverseLoD in order to fit the accuracy required by each step of the research

Panoramic UAV Views for Landscape Heritage Analysis Integrated with Historical Maps Atlases

Analysis of landscape heritage and territorial transformations dedicated to its protection and preservation rely increasingly upon the contribution of integrated disciplines. In 2000 the European Landscape Convention established the necessity 'to integrate landscape into its regional and town planning policies and in its cultural, environmental, agricultural, social and economic policies'. Such articulated territorial dimension requires an approach able to consider multi-dimensional data and information from different spatial and temporal series, supporting territorial analysis and spatial planning under different points of view. Most of landscape representation instruments are based on 3D models based on top-down image/views, with still weak possibilities to reproduce views similar to the human eye or map surface development along preferential directions (e.g. water front views). A methodological approach of rediscovering the long tradition of historical water front view maps, itinerary maps and human eye maps perspective, could improve content decoding of cultural heritage with environmental dimension and its knowledge transfer to planners and citizens. The research here described experiments multiple view models which can simulate real scenarios at the height of observer or along view front. The paper investigates the possibilities of panoramic views simulation and reconstruction from images acquired by RC/UAV platforms and multisensory systems, testing orthoimage generation for landscape riparian areas and water front wiew representation, verifying the application of automatic algorithms for image orientation and DTM extraction (AtiPE, ATE) on such complex image models, identifying critical aspects for future development. The sample landscape portion along ancient water corridor, with stratified values of anthropogenic environment, shows the potentials of future achievement in supporting sustainable planning through technical water front view map and 3D panoramic views, for Environmental Impact Assessment (EIA) purposes and for the improvement of an acknowledged tourism within geo-atlas based on multi-dimensional and multitemporal Spatial Data Infrastructures (SDI)

VIRTUAL MUSEUMS AS DIGITAL STORYTELLERS FOR DISSEMINATION OF BUILT ENVIRONMENT: POSSIBLE NARRATIVES AND OUTLOOKS FOR APPEALING AND RICH ENCOUNTERS WITH THE PAST

Virtual Museums (VMs) have emerged from the ongoing crossbreeding process between museums and digital technologies as an additional "channel" for disseminating content and providing knowledge about cultural heritage. VMs is a concept still in definition, as this paper attempts to briefly retrace, the recognition of its potential has motivated our efforts for further developments. Core questions that motivated the first phase of the research presented have been: can digital storytelling become the key feature of future VMs? May narratives approach support communication and understanding of cultural heritage providing enriching encounters with the past? May complex systems, such as the built environment and landscape (characterized by space-time relations among elements, that are often difficult to read or appreciate) find in digital storytelling a method that exploits their values as documents and palimpsests of human history? Can an increased awareness of the past contribute to support a sense of belonging and identity construction? Which kind of stories can be currently designed with the existing tools? The paper, after an introductory overview, provides a tentative reply to these questions combining the main findings offered by a series of recent studies related to this scenario with some preliminary direct investigations and, eventually, it proposes some outlooks for future developments
