The Laboratory aims to provide the basics of Geomatics required to approach the metric survey of the architectures and of the urban spaces by using appropriate technologies and methodologies. Fundamental methods and metric survey techniques (2 CFU) and field’s applications (4 CFU) will be investigated: the "metric" meaning define the contribution of topographical and photogrammetric techniques that coincide with the English definition of "Metric Survey". According to the main learning goal of the Laboratory, the main focus of the different instrumental methods is the planning and validation of the metric and semantic quality of the (digital) data and related added value information. The proposed approach is based on the acquisition, modelling and representation of real-world objects in accordance with the goals of the pre-defined analysis (e.g. planning, restoration, management)

The Laboratory aims to provide to the students the theoretical and operational knowledge required to design a metric survey meeting the interpretative and descriptive requirements of the built space and of the architectural objects. Particular attention is given to the ability to adopt different Levels of Detail in the interpretation of the architectural objects to obtain a scaled model.

The expertise acquired during the first year of the course in Architecture is requested, specifically the basic knowledge of the representation methods as defined by the critical interpretation of the architectural shape and the graphical norms for the adopted representation scales.

The theoretical basics of the metric survey methods and technologies will be provided and exploited in an operational case study with the goal to derive architectural models and drawings (vector format) by means of (archived) 3D data processing. Standard guidelines defined in the Cultural Heritage documentation domain and commonly used for professional activities are adopted, i.e.: topographical methods based on the use of digital total stations; different software tools to process and manage digital survey data; image geometric transformations (rectification); manual and semi-automatic photogrammetric processing; 3D data management in CAD environment; raster-vector integration and representation. Basic consideration about image-matching based photogrammetric algorithms (also known as photo-modelling) will be also described beside the management of 3D point clouds, 3D modelling strategies and orthoprojection approaches. The main focus will be on the validation of the metric accuracy of the outputs and on the quality of the graphical deliverables. Some activities will be directed to test the coordination with activities of the "City and Territory Studio" that the students attend in the same semester, and aimed at supporting the use of mapping materials and related management tools.

The organisation of the Laboratory consists in theoretical lessons to face the theoretical basics of the metric survey techniques; they will be tested by means of a practical activity which allow to learn the basic on the acquisition of the primary data by using total stations and/or the primary data for a photogrammetric survey. The acquired data will be handled through specific software enabling image rectification and digital photogrammetry processing to generate 2D outputs (e.g. plans, sections, elevations) as well as 3D models (e.g. point clouds or mesh models).

The teacher will furnish all the material used during the lessons and related notes about the theoretical arguments approached by using the web site of the Laboratory. References related to general arguments and deep investigation on specific items will be given by the teacher during the lessons also by considering the specific example examined during the practical phase.

Modalità di esame: Prova orale obbligatoria; Elaborato grafico prodotto in gruppo; Prova scritta tramite l'utilizzo di vLAIB e piattaforma di ateneo;

The exam is aimed at assessing: i) the knowledge of the theoretical topics related to 3D metric surveying discussed during the lectures ii) the ability to apply the operational methodologies related to data acquisition and processing and tested during the exercises. During the development of the practical activity, the intermediate results of each step of the survey workflow (metric survey, drawings and modelling of the architectural elements) will be tested. This action is aimed at guaranteeing that the students are able to face the final exams at the end of the teaching activities. The final evaluation will be based on the following tests, that will contribute with the same weight to the final score: - evaluation of the 2D and 3D graphical outputs produced by the student groups. - on-line written exam with Respondus with open questions on the theoretical basics (test time ~1 hour, use of support material is not allowed, individual evaluation); - individual or group (on-line or on.site) oral exam, aimed at discussing the results of the written test and the group graphical outputs. The final evaluation will consider the graphic deliverable, the results of the written test as well as the personal involvement in the group activities and the communication skills.
