The training course is delivered both by theoretical lectures and labs; in the latter, students will use PC to process digital images based on real cases. Every student will access a single PC and will be assisted during all the labs. For the theoretical and labs parts, digital contents will be available since the beginning of the training course and labs will be duplicated based on the number of students attending. Innovative learning will be used, facilitating student’s interaction and organizing a final full day challenge based on the ability to approach a complex environmental issue using open source remotely sensed imageries and mapping data.

The teaching is organized in lessons and operational activities developed with the help of the Envi software. The former are dedicated to the presentation of the theoretical and methodological aspects of the phenomena examined; the latter are aimed at understanding, from an operational point of view, the methods of management, processing and extraction of information from large quantities of data acquired by sensors mounted on board of aerial and satellite platforms.

The exam consists of an oral test aimed at assessing the theoretical skills and the ability to integrate the results of geophysical surveys into different application contexts. The exam is organized with a question about theoretical aspects and one question about planning and carrying out surveys and interpretation of results. The discussion of the laboratory activities is also part of the exam. The final evaluation is based on the clarity of exposition (5 points), technical skills (5 points), capability to relate the different aspects of the subject (10 points), degree of competence achieved (10 points).

Evaluation will be based on written and/or oral examinations, both from theoretical and lab parts, and based on the official programme and the lab exercises. Examination could be taken both written and oral; the written examination consists of two different test based on the theoretical and experimental parts. In the first, the candidate should answer to 3 different questions, while in the second, using a PC and a standard software, the candidate will answer to a set of different questions. Results of the examination are then delivered to students by means of didactic portal. Oral examination consists of a set of three questions based on theoretical part and the candidate is then asked to solve, with the usage of a PC and a standard software, a practical exercise.

The exam will consist in an individual written divided in three parts: 1) processing of geophysical data according to the tools and the platform introduced during the course (Matlab/Octave); 2) planning a geophysical survey on some specific issue (mining, climate change, environmental); 3) exercises on the relationships between geophysical and engineering properties and/or theoretical questions The main goal is to evaluate the capability of students in planning and design geophysical survey, to interpret the data sets and in understanding the theoretical aspects of the applied geophysics. The exam will last 60 minutes; students will be allowed to consult only the form made available by the teacher for exams. The final evaluation is based on the clarity of exposition (5 points), technical skills (5 points), capability to relate the different aspects of the subject (10 points), degree of competence achieved (10 points).

The exam is aimed at verifying the achievement of sufficient autonomy in tackling an environmental problem using Earth observation data processing techniques useful for extracting added value information. The theoretical part will be evaluated through a written exam (duration 1.5 hours) in which the student will have to answer at least three questions concerning the different topics proposed during the course. The experimental part will focus on the drafting of a report based on the elaboration of Earth observation data based on a topic and on an area freely chosen by the student. Students with disabilities or with Specific Learning Disorders (OSA), in addition to reporting via computerized procedure, are also invited to communicate directly to the teacher in charge of the course, with notice of at least one week from the start of the exam session, the compensatory tools agreed with the Special Needs Unit, in order to allow the teacher the most suitable declination with reference to the specific type of exam.
