A large part of political decisions are taken considering the spatial data, which are the basis for the knowledge of the land, of the built areas as well as support to the urban development planning and to the engineering design. Human activities require then to know position and to be able to navigate to acquire 3D data in a kinematic way either to reach a location or to follow a route. Even in everyday life, products such as Google Earth are becoming increasingly popular and used as they allow to plan and organize activities. The acquisition, processing and representation techniques for spatial data significantly evolved in the last two decades, thanks to the increased use of technologies coming from the ICT sector. Techniques of 3D data acquisition and instrumentation, have been improved thanks to the use of Global Navigation Satellite systems (GNSS) as the GPS, Laser Imaging Detection and Ranging (LiDAR) systems, digital images and inertial systems. Furthermore, novel processing techniques allow to optimally integrate sensors and led to improve the representation of the land and the management of data related to it through GIS (Geographic Information System) techniques. The ICT field must then interface with skilled users who work on georeferencing, processing and plotting of spatial data. It is often necessary to develop software or firmware that meet the requirements of positioning, representation and the organization of databases of geo-referenced data, or at least to become skilled users of these technologies. This course provides the basic principles of the techniques of acquisition, processing, plotting and representation of spatial data, to create ICT professionals that know how to interface with the operators in the Geomatics field, supporting the knowledge and control of the land and built areas.

This course provides the basic principles of the techniques of acquisition, processing, plotting and representation of spatial data, to create ICT professionals that know how to interface with the operators in the Geomatics field, supporting the knowledge and control of the land and built areas.
The lectures aim at providing the theoretical principles of the different measurement and spatial data acquisition techniques, the knowledge of statistical data analysis, the applications of Geomatics techniques for the land surveying, buildings and civil engineering activities, mapping, monitoring and protection of the land. The practical parts are focused to develop the operational skills on the basis of the theoretical knowledge. The student will be trained to perform spatial measurements by means of the most up-to-date surveying techniques and to manage the different techniques for acquisition of positioning data, while assessing the robustness in presence of intentional and unintentional disturbances. In this course abilities of data processing of on-field measurements will be developed. Practical problems will be proposed: the student will be required to autonomously develop computational procedures for the implementation of Geomatics applications, in particular concerning the monitoring and representation of the land and of the built areas. The student will have to achieve the ability to exploit the skills acquired in the ICT domain to the fields of navigation and mapping. He will develop the ability to implement calculation tools and procedures for positioning, representation and visualization of spatial data for land and built areas monitoring.

Modalità di esame: Prova orale obbligatoria; Elaborato scritto individuale; Prova scritta in aula tramite PC con l'utilizzo della piattaforma di ateneo;
Exam: Compulsory oral exam; Individual essay; Computer-based written test in class using POLITO platform;
The exam is organized in 2 parts: a preliminary multiple answer test and an oral discussion with the student about the topics explained during the course. The report on the lab activities contributes to the final grade of the exam. The multiple answers test is made by 10 questions (5 ICT and 5 Geomatics) on the topics of the course, and it is necessary to have 6 right answers out of 10 in order to proceed to the oral exam. The questions of the oral exam aim at testing the knowledge of the theoretical concepts on positioning, spatial data acquisition and GIS, as well as the ability to apply them to solve position and navigation problems. The oral exam will be composed at least by two questions on satellite navigation and ICT part, and two questions on Geomatics part of the course. They both contribute for the 50% to the final grade, but it is necessary to achieve a positive mark (>18/30) in each single part. Each student must deliver a mandatory individual report on the laboratory activities developed during the course This report will be evaluated on a score range from -1 to +2. These points will be added to the evaluation of the oral exam. The score -1 is given in case either of no delivery or very bad quality of the report, while the other additional points will consider the ability of the student to solve the task required by the lab activities, completeness of the work performed, the quality of the report itself (organization of the content, quality of the figures, correctness of the solution etc..) and the methodology employed. The report must to be uploaded in the "portale della didattica" within one week after the end of the lessons.

The report of each assignment must be uploaded in the "portale della didattica" during the course, according to the deadline defined by the teachers. The final grade is composed by: 1/3 (result of multiple-choice) + 2/3 (oral exam) + bonus (report).
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.
