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.

Learning outcomes and their assessment

Requirements for awarding credit points

Written exam.
The exam task consists of:
- test on the theoretical subject acquired in the study course;
- practical task on the topics acquired in the study course laboratory works and homework.
All laboratory works, tests, homework must be included.

Description of the organization and tasks of students’ independent work

1. homework.
Research of engineering geodetic measurement process for a specific object during construction or operation period (volume at least 15 pages, submitted electronically, presented);
2. homework.
Development of a geodetic observation plan for a specific construction object (developed graphic project and descriptive part, submitted in electronic form, presented).
Feasibility study of the object necessary for surveying the topographic plan, selected geodetic instruments, geodetic substantiation of the topographic plan, elements of the surface and underground situation to be displayed in the topographic plan, representation of boundaries and protection zones in topographic plans

Criteria for Evaluating Learning Outcomes

The evaluation of the examination of the study course depends on the evaluation of the theoretical questions and the solution of the task of the examination, and the cumulative evaluation of the study course tests and homework. All planned laboratory works must be completed and credited. Attendance at lectures must be at least 75% of the total.
A student can obtain a successful mark on a test or exam test if at least 50% of the test questions are answered correctly.
Students who study this course test mark at least 7, examination theoretical examination may not fulfill the test, and the theoretical assessment equated to the average of the course test marks.
The examination mark is calculated as the arithmetic mean of the examination tasks and the average semester mark, which is calculated as the arithmetic means of the marks of the tests and homework taken in the study course.
