Geodesy

Description: The students acquire skills and abilities to perform a complex of geodetic work required in the design, construction and operation of engineering structures using modern geodetic equipment (topographic surveys for the preparation of topographic maps and plans, the creation of planned and high-altitude surveying base, mathematical processing of geodetic measurements, solving problems on topographic maps and plans).

Amount of credits: 5

Course Workload:

Component: Component by selection

Cycle: Base disciplines

Goal

• To provide students with an understanding of: - the composition and content of the topographic and geodetic work carried out in the creation of a topographic base for surveying, design and construction of buildings and structures; - transfer of projects into real estate; - methods of geodetic support during construction of various engineering objects (buildings, roads, hydraulic structures, bridges, pipelines).

Objective

• The student should know the composition and technology of geodetic works, providing design and construction of various engineering objects (buildings, roads, hydraulic structures, bridges, pipelines); technology of certain types of geodetic works for various land cadastral activities; methods of geodetic measurements and executive surveys, methods of mapping of land resources.
• The student should be able to: - read a topographical map fluently and solve graphical and calculation tasks on its basis; - independently carry out simple geodetic measurements and works related to solving typical design and construction tasks by means of geodetic tools and instruments; - carry out mathematical processing of measurements (calculation of coordinate statement, straight and curve statement, processing of total station survey log, technical levelling log); - graphically design the results of measurements (construction of topographic plan, longitudinal and transverse profiles, plans of horizontal and vertical leveling with mapping of earthworks).

Learning outcome: knowledge and understanding

• Knowledge of: - specifics of topographic and geodetic work; - geodetic instruments and tools used for geodetic measurements, methods of topographic mapping (plans).

Learning outcome: applying knowledge and understanding

• Skill to apply modern methods and type of geodetic works in geodetic support of objects of economy with the use of modern technologies and software.

Learning outcome: formation of judgments

• Ability to analyze information, make reasoned judgments, and draw well-founded conclusion about the methods of making various surveying measurements and the conditions of their application

Learning outcome: communicative abilities

• Ability to work effectively individually and as a team member with shared responsibility and authority in solving complex problems.

Learning outcome: learning skills or learning abilities

• Skills in the use of surveying instruments and tools.
• Ability to compile geodetic technical documentation.

Teaching methods

Interactive lecture (application of the following active forms of learning: guided (guided) discussion or conversation; moderation; demonstration of slides or educational films; brainstorming; motivational speaking);

Construction of scenarios for various situations based on the given conditions;

Information and communication (e.g. lessons in a computer class using professional application software packages);

Search and research (independent research activity of students in the learning process);

Learning problem solving.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
