  • Il City Information Modeling (CIM) nelle piattaforme decisionali urbane

    • Authors: Renzo Carlucci
      Abstract: To evaluate how the CIM contributes to improving public services and the quality of life of citizens, studies conducted by some authors have analyzed the international standard ISO 37120 - Sustainable cities and communities - Indicators for
      city services and quality of life and City Information Modeling (CIM) data that can be used to obtain useful data for ISO indicators 37120. The CIM paradigm, understood as an approach to a global model of the city, must absolutely be formed
      by the incorporation of BIM models of buildings that have a geographical insertion in the reference system in use. In this way all the data relating to the cities will be available and attached to the georeferenced representations of the buildings present
      in the CIM database.

  • Multispectral satellite images to support the CIM (City Information
           Modeling) implementation

    • Authors: Donatella Dominici, Maria Alicandro, Donato Di Ludovico, Nicole Pascucci , Sara Zollini
      Abstract: This work shows the processing of additional information using high and medium-resolution multispectral satellite
      images. The new information obtained from specific spectral indices will converge with the data obtained from
      official sources in a single database, thus constituting a real parametric model of the city under study. An extended model
      of urban planning called “CIM” (City Information Modeling) will be developed, to which it is possible to associate
      information of different nature, which helps to monitor and manage the city.

  • SLAM-to-BIM con Stonex X120GO

    • Authors: Chiara Ponti
      Abstract: 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.

    • Authors: Valerio Zunino
      Abstract: Accompagnata da una delle sue inseparabili caratteristiche, quella di operare sempre un po' sottotraccia anche ove individuata quale supporto necessario e fondamentale a servizi di pubblica e primaria utilità, la cartografia sta oggi conoscendo uno step evolutivo importante, dal momento in cui i grandi player della navigazione per auto e - un po' più defilate - le solite Big Tech, hanno manifestato (come al solito soltanto i primi in modalità esplicita) quei progetti che discendono dall'ambizione che è causa delle loro nuove sfide di mercato.

  • La cattura della realtà coinvolge tutti gli operatori

    • Authors: Teorema Milano
      Abstract: Teorema has been dealing for years with the offer of instruments for 3D digitization of buildings and environments, which are increasingly in demand as technological evolution advances. In this article, it is highlighted the importance
      of Reality Capture in the construction world, connecting several professionals involved in the construction process.
      This technology allows the replication of the physical world and its transformation into a virtual environment and
      can be used to monitor the progress of a project and quickly compare whether the construction follows the design
      plan, ensuring quality control and highlighting any problems.

           TERRENO” DAL PALLONE (1908)

    • Authors: Laura Castrianni
      Abstract: The paper describes time, modes and techniques of realization in 1908 of a photomosaic, from balloon, of a section of the course of the Tiber river. The photomosaic was carried out by the Brigata Mista Specialisti of Genio Militare headed by Captain Cesare Tardivo, on order of the Genio Civile, as part of a navigation project of the Tiber river from the sea to Orte. The pioneering photomosaic, regarding the 50 km section from Ponte del Grillo to Stimigliano, is kept at the photographic archive of the Aerofototeca Nazionale - ICCD, and it is the first application of the new tecnique called topophotograpy in the civil field: presented as the "true portrait of the terrain" at the main international conferences of the time, earned Italy an undisputed leading place in the field of aerial photography and photogrammetry.
