The course is aimed to supply the theoretical and practical foundations of Remote Sensing. The use of GIS software for the processing of remotely sensed data concerning the sea and the territory is included.
Knowledge and understanding: The student must demonstrate knowing the principles, methods and tools of Remote Sensing needed to solve theoretical and practical problems in the field of surveys by aircraft or satellite.
Ability to Apply Knowledge and Understanding: The student must demonstrate the ability to use theoretical and practical concepts acquired for remote surveys as well as for processing data acquired by satellite or aircraft.
Judging autonomy: Students must be able to independently evaluate situations that are different from the standard ones presented by the teacher during the course and to adopt the best methodologies.
Communicative Skills: The student must have the ability to develop and present themes concerning Remote Sensing by using the technical-scientific language correctly.
Learning Skills: The student must be able to update continuously his knowledge through consultation of texts and publications in order to acquire the ability to deepen the topics of Remote Sensing.
Basic knowledge of Physics and Mathematics is required.
