LEARNING OUTCOMES
After the end of the course, students will have acquired fundamental knowledge of Geodesy and Topography, as well as a general overview of the subjects of Surveying Engineering, while at the same time they will have become familiar with the basic field topographical work and
measurements. The context of the course aims at understanding the theory and solving the practical issues that arise in the basic geodetic engineering tasks assigned to the students. Finally, it is expected that students will develop critical thinking about problems of basic work performed by the Surveying Engineer, and will be able to resolve them
General Competencies
• Search, analysis and synthesis of data and information, using the necessary technologies.
• Autonomous work.
• Teamwork.
• Criticism and self-criticism.
