2. Objectives and learning outcomes

2.1 Objectives

The aim of this course is to learn the basic concepts of Surveying, the structure of surveying instruments and the basic surveying observations and their processing, such as the optical levelling (line levelling, detail point levelling), the application of the theodolites and total stations and horizontal and vertical angular observations. Students will learn and practise the units used in surveying as well as the math solutions of coordinate and elevation computations.

2.2 Learning outcomes

Upon successful completion of this subject, the student:

A. Knowledge

- Knows the basic concepts and functions of surveying and geodesy
- Understands the structure and the variants of surveyors' levels.
- Knows the possible solutions of height determination.
- Knows the implementation of line levelling and detail point levelling as well as the processing of measurements.
- Knows the systematic errors of levelling and the procedure and rules of levelling
- Knows the way of implementation of trigonometric heighting and the systematic errors and their considerations
- Knows the structure of the theodolite as well as the basics of its examination
- Knows the systematic errors of angular observations and how to handle them
- Knows the basics units used in surveying
- Has a general knowledge of the projections and control networks used in practise and also knowhow to access surveying data
- Knows the fundamental tasks of surveying calculations and the orientation of mean direction

B. Skills

- Able to use the units used in surveying and to convert between them
- Able to perform height determination with levelling
- Able to set up theodolites/total stations and to carry out measurements of directions and zenith angles
- Able to process measurements of directions and zenith angles as well as to correct the systematic errors
- Able to reduce distance observations to the reference level (mean sea level)
- Able to orient the observed mean directions, and to calculate the horizontal coordinates of unknown points using the 1. and 2. fundamental tasks of surveying

C. Attitudes

- Collaborate with the professor and other students
- Attempts to acquire the knowledge to use the necessary instruments to perform surveying tasks
- Attempts to effectively use builtin programs and memory functions of calculators
- Attempts for accurate and errorfree calculations, take advantage of control alternatives

D. Autonomy and Responsibility

- Independently practise the usage of theodolite and prepare for the practical test
- Openly receives the wellfounded critical comments

2.3 Methods

Lectures, computation and measurement exercises, communication in writing and oral, use of IT tools and techniques, tasks independently and teamwork, logistic techniques.

#### II. Subject requirements

Assessment and evaluation of the learning outcomes

3.1 General rules

The assessment of the learning outcomes specified in clause 2.2 above and the evaluation ofstudent performance occurs via two midterm tests, a practical report and a written exam in the examination period.

3.2 Assessment methods

Evaluation form |
Abbreviation |
Assessed learning outcomes |

1. Midterm test | MT1 | A.2, A.3, A.4, A.5; B.1, B.2; C.3 |

1. Practical report | PR1 | A.7, A.8; B.3, B.4; C.1 C.3; D.1, D.2 |

2. Midterm test | MT2 | A.9, A.10, A.11; B.1, B.6; C.3, C.4 |

2.Exam | E | A.1-A.12; B.1-B.6; C.3-C.4 |

The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.

3.3 Evaluation system

To successfully gain the signature of the subject it is compulsory to acquire at least 50% of the points of the midterm tests. To complete the subject, the practical report must also be completed. To successfully complete the practical report, the given
measurement and data processing task has to be completed correctly, within a specified time limit.

Students must sit an exam after successfully obtaining the signature from the course.

The weights of the assessments are as follows:

Abbreviation |
Score |

MT1 | 20% |

PR1 | 0% (must be fulfilled) |

MT2 | 20% |

midterm in total |
40% |

3.4 Requirements and validity of signature

To successfully gain the signature of the subject it is compulsory to acquire at least 50% of the points of the midterm tests. To complete the subject, the practical report must also be completed. To successfully complete the practical report, the given measurement and data processing task has to be completed correctly, within a specified time limit.

Minimum requirements:

- MT1 and MT2 a minimum requirement is 50% of the maximum points;

- PR1 must be passed

- a minimum attendance of 70% on both the lectures and the practicals are required

The validity of the signature is two years after its achievement.

Minimum requirements:

- MT1 and MT2 a minimum requirement is 50% of the maximum points;

- PR1 must be passed

- a minimum attendance of 70% on both the lectures and the practicals are required

The validity of the signature is two years after its achievement.

3.5 Grading system

The final grade is defined as the lump sum of the MT1, MT2 and the Exam points.

To achieve a final grade the students must hold the signature from the course and earn the minimum of 50% on the exam.

The grade points are calculated as follows:

P = MT1 + MT2 + E,

where

- MT1 is the midterm test 1 with a maximum of 20 pts;

- MT2 is the midterm test 2 with a maximum of 20 pts;

- E is the written exam test with the maximum of 60 pts.

Grade |
Points (P) |

excellent (5) | 88-P |

good (4) | 76-87 |

satisfactory (3) | 63-75 |

pass (2) | 50-62 |

fail (1) | -49 |

3.6 Retake and repeat

- Minimum requirements are specified for both mid-term tests and the practical tests. Thus, all of them can be retaken once.
- In case of retaking anassessment the second result will be taken into account from the new and previous results.
- In case of failing the retake, there is a possibility for a second retake for 2 of the aforementioned assessments - after the payment of the predetermined fee in the completion week from
