The Municipality of Perugia adopts an innovative approach to respond to current urban challenges. The city's digital twin constitutes a cutting-edge solution for the city's transition towards a digital, sustainable and participatory environment. [ABSTRACT FROM AUTHOR]

Everything is there, everything was already there, in fact almost... everything. On this "almost" rests and resides one of the main (the main, on a technical level) reasons for the ongoing dialectical revolution. That is, if a little while ago we asked ourselves why there is so much insistence today on the communication of things that could have been achieved in the past, then certainly the world of machine learning and neural networks are giving a strong push to the much faster and more massive 3D geographical restitutions, whether derived from traditional digital photogrammetric (better to specify) or LIDAR, and the matter allows gross minimization in production times and consequent cost reductions per square kilometer returned, therefore certainly representing a convincing element for understanding the push towards new market paradigms whose explosion we too are witnessing, in the geospatial sector.

Downstream from Sityround, we work every day to enable effective digital management of virtualized assets, not only through "simple" 3D modeling (first almost elementary result of survey activities) or through the consequent accurate calculation of volumes, but rather animated by desire to provide a real tool for the current and continuous management of the historical, architectural and building heritage, where each of the geometric elements of the valuable artefacts finds the opportunity for its own geocoding, in which the information characterizing the element, descriptive patrimonial, maintenance and customs, inextricably linked to the individual dimensional components of the point cloud itself and the photographic heritage that gives rise to it.

Cities nowadays need to have long-term visions and perspectives to achieve the ambitious targets for which vast investments are being made. They need to act with competence and capability-based planning, and to come up with suitable solutions. Technology is unquestionably a factor of crucial importance when aiming for these targets. Digital innovation, based on data knowledge, analysis and projection, is crucial to tackle the most demanding challenges of our times. The methodological approach proposed here is an Urban Digital Twin applied to cities as a predictive model to obtain a projection of their development in terms of sustainability.

The digitalisation of the building process is increasingly present on the world scene. The methodology that leads to 3D models of construction projects and buildings is called BIM (Building Information Modelling). This methodology has the great advantage of associating different types of information (spatial, temporal, structural, etc.) with the three-dimensional model, thus making it possible to create an information system that can be shared between the various stakeholders involved in the design and construction process of a building. The BIM model also becomes the basis for the development of the so-called Digital Twins, models that integrate information on the use of the building over time and provide important analysis tools for maintenance planning. The surveying methodologies for the creation of BIM most widely used today are photogrammetry and laser scanner surveying. In both cases, the product of the survey are point clouds, i.e. sets of measured points that contain information on the position of the surveyed elements and possibly their colour. Point clouds are an extremely suitable product for BIM, as they are already three-dimensional and can be queried. However, in the case of large buildings or environments with special features, surveys with traditional static lasers (on tripods) can require long time. For this reason, in recent years, the world of topographic surveying has adopted innovative instruments that allow data to be acquired in motion, thus reducing scanning and processing times, the SLAM laser scanners. Stonex has developed a solution that combines precise sensors with a robust SLAM algorithm to produce clean, and accurate point clouds easily usable for BIM creation: the new SLAM X120GO laser scanner. This system features a 360° rotating LiDAR head capable of generating a point cloud coverage of 360° x 270°. In combination with IMU data and the SLAM algorithm, it is able to obtain high-precision threedimensional point cloud data of the surrounding environment without light and GPS. Equipped with three 5MP cameras to generate a horizontal 200°FOV and vertical 100°FOV, it can synchronously obtain texture information and produce colour point clouds and partial panoramic images. Both features are very useful in the BIM authoring phase. With a range of 120 m, the X120GO is suitable for working both indoors and outdoors, even in challenging environments, allowing the survey of an entire building to be completed with a single instrument. The X120GO has an integrated structure that makes it easy to move around the scanning environment. Thanks to the GOapp Android application, you can manage the scanner and observe the creation of the point cloud in real time. Once the start button is pressed, the X120GO can begin operations immediately, making data acquisition efficient and convenient. During data acquisition, the X120GO is also able to collect control point coordinates, which can then be combined with known points to georeference scans. [ABSTRACT FROM AUTHOR]

ART GRAPHIQUE & PATRIMOINE, PIONEER OF NEW TECHNOLOGIES AND EXPERT IN CULTURAL HERITAGE, HAS JOINED THE "ETABLISSEMENT PUBLIC" IN CHARGE OF THE CONSERVATION AND RESTORATION OF NOTRE-DAME AND THE CNRS - NATIONAL CENTER FOR SCIENTIFIC RESEARCH - IN THE CONTEXT OF THE CREATION OF THE "DIGITAL TWIN" OF THE CATHEDRAL. IN MARCH 2021, TWO YEARS AFTER THE FIRE THAT DESTROYED THE MEDIEVAL ROOF AND TRUSSES, AGP COMPLETED ITS WORK ON THE DIGITAL NOTRE-DAME PROJECT. [ABSTRACT FROM AUTHOR]

Teorema Milano, BLK Leica Premium Partner, is a company specialized in the distribution of tools for three-dimensional surveying. The use of the digital representation of 3D models is gaining more and more importance in documenting building construction processes, but also in many other areas. However, as popularity increases, false ideas can also arise. All over the world, reality capture technology developed by Leica Geosystems has given many projects a glimpse into the future. Long gone are the days of recording construction site conditions with a tape measure, spending hours crunching numbers and collecting data by hand, point by point. Reality capture was born out of existing and new innovative technologies fused together to capture digital datasets. This technology has allowed users to implement millions of pieces of information directly into the digitization process in order to create complete 3D models. Reality Capture has turned into a tool for capturing the surrounding world by transforming it into digitally manageable information (data, point clouds) as well as flat and two-dimensional static snapshots. We are now able to capture 3D digital twins, also known as digital realities: replicas of objects, people or places in the physical world created in digital form. Since the creation of the Digital Twins we have evolved towards a Smart Digital Reality that brings autonomy to the digital twin to transform its function and utility. Using technologies such as machine learning and artificial intelligence (AI), we can create systems to reduce, or even eliminate, human intervention and develop dynamic workflows that integrate the right data, in the right place and at the right time. Users can leverage data to empower their applications to self-resolve problems, increasing efficiency, productivity, quality and safety across industries. However, as reality capture technology evolves and becomes more widespread, some false myths have been created that we will see in this article. [ABSTRACT FROM AUTHOR]

The European Association of Aerial Surveying Industries (EAASI) closed a successful edition of its Partners Summit last 2 December. More than 70 representatives from 40 companies connected to the aerial surveying industry gathered in Rome for 3 days to discuss the current challenges of the industry as well as explore new business opportunities. The participants attended a series of presentations, panel discussions, and workshops covering a wide range of topics such as climate change, digital twins, or certification and standardization, among others.
