Geomatics’ techniques and tools allow to manage georeferenced spatial data and to generate added value information and can be applied in multiple application areas (i.e., decarbonization processes, industry 4.0, cultural heritage, etc.) and in response to various challenges (i.e., sustainable mobility, optimization of industrial processes, predictive maintenance, digital twins, innovative dissemination tools). In this context, Geographic Information Systems (GIS) play a key role, allowing to acquire data, to position them with respect to a reference coordinate system (georeferencing), to structure them effectively, to analyze them, to share them and to generate innovative and effective dissemination products. This course aims to: • describe GIS systems peculiarities and GIS different data types • describe how spatial data can be navigated, queried, visualized and combined into mapping products • showcase methods and tools for creating new data and analysing existing ones • demonstrate the application of these techniques in different areas through practical examples, presented during lessons, and the production of a final report by the students on a topic of their choice.

• Knowledge of the main types of geographical data and the related methods of creating, editing, processing (with hints relating to automation through scripting) and representing • Ability to manage spatial data in different reference and coordinate systems • Ability to communicate issues of spatial relevance in a clear and unambiguous way through the preparation of a report on original themes and which includes cartographic outputs
At the end of this course, the student will be able to: • define the main types of geographic data • explain precision and accuracy concepts in relation with geographic data nominal scale • use methods for creating, editing,and representing geographical data • convert geographic data in different coordinate systems • process (with hints relating to automation through scripting) geographic data and evaluate the derived results • formulate a report to communicate geographic data analysis outputs in a clear and unambiguous way
Basic computer literacy.

Modalità di esame: Prova orale obbligatoria; Elaborato scritto individuale; Elaborato scritto prodotto in gruppo;
Exam: Compulsory oral exam; Individual essay; Group essay;
The exam will be oral and will focus on the presentation and subsequent discussion of a report in which students, individually or in small groups of maximum 3 people, will have to demonstrate the application of conceptss, methods and analyses presented during the course. The written document must be a descriptive and self-explanatory text, designed to provide a complete picture of the objectives, methods, and results. It is advisable to follow the instructions in the document Knowing how to communicate (https://didattica.polito.it/tesi/SaperComunicare.pdf), as regards the production of a technical-scientific report (section 2). The level of detail of the report must be a good compromise between the readability of the document and the need to provide the reader with the tools not only to understand the analysis, but also to be able to reproduce (and possibly improve) the proposed procedure. The subject of the paper should be agreed in advance with the teacher: in this case, the material necessary for the assessment must be delivered 1 week before the exam date. If the object is not agreed, the material needed for the assessment must be delivered within 2 weeks from the date of the exam. All the topics covered during the course and, if necessary, their application using the adopted GIS software, installed in the laboratory or on student’s PC, are an integral part of the oral exam. The judgment criteria used to compose the final grade include the evaluation of: • the ability to produce a concise, coherent and unambiguous written paper (45%) • the ability to expose the contents of the paper clearly and in accordance with the indicated time (25%) • the theoretical knowledge relating to the topics covered during the lessons (30%)
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
