Course abstract

In the study course students practically acquire the theory and practice of geodesy application in solving various engineering tasks and topography. Learns to perform calculations and graphic works for the development of the road project, to perform the technical substantiation of the developed work. Learns topographic surveying methods. Learns to process topographic measurement data. Learn topographic notation. Acquires skills for making a topographic plan.

In part-time studies:
All topics indicated for full-time attendance are implemented, but the number of contact hours is 1/2 of the indicated hours

Requirements for awarding credit points

Written exam. A course project must be developed and defended.

Description of the organization and tasks of students’ independent work

Research of special literature and regulatory acts on the importance of roads in the national economy, types of design and activities. Development of the course project. The student develops the project work in accordance with the course project assignment and methodological instructions issued by the lecturer, submits and defends it within the deadlines agreed with the lecturer.

Criteria for Evaluating Learning Outcomes

The evaluation of the study course exam depends on the evaluation of the theoretical questions and task solutions of the exam, and the evaluation of the study course tests and course work. All planned laboratory work must be completed and passed. 4 theoretical questions and one practical task are asked in each test. You can get up to 5 points for each test. The test is passed successfully if at least 3 points are obtained. The student is allowed to take the exam if both tests are written successfully. If the student has scored 7 or more points in both tests, he can receive an assessment without taking the exam. Written exam on the theoretical material learned in the study course.
Attendance at lectures must be at least 75% of the total amount.
