At the end of the course, after passing the final test, the student has the basic knowledge of geodesic elements, reference systems and coordinates. He has acquired the theoretical and practical bases for the use of topographic instruments and satellite positioning techniques. It knows how to statistically process observations made according to polygonal survey schemes and simple networks. He knows the introductory concepts of the theory of cartographic representations, in order to create and use cartographic works at different scales and can set up a drone photogrammetric survey of a portion of land.
An inductive approach to the topics covered is proposed. Techniques and tools are shown to students, as well as their application to real case studies. The theoretical and methodological aspects are discussed in depth during the lessons of the course.
Frontal lessons alternate with practical and computational exercises.
