Computer Graphics in Geoinformatics

Course developers

Course abstract

The aim of the study course is to gain insight into the history of drawing programs, get acquainted with the application of the latest programs, their positive and negative features; gets acquainted with the engineering design programs MicroStation and AutoCad, with the working environment of the programs and their use in the representation of geospatial data, as well as in the preparation of other graphic materials, area determination and design works. Students learn to draw various architectural elements, design plans and other drawings, and prepare them for printing in MicroStation and AutoCad environments.

Learning outcomes and their assessment

MicroStation
1. Knows the principle of operation of the MicroStation program, the possibilities of MicroStation in drawing topographic plans and other graphic materials, defining areas and designing. Knowledge should be assessed during the development of laboratory works.
2. Is able to draw topographic plans and other types of graphic materials using various drawing, editing and other palettes. Is able to adjust plans and prepare for drawing. Skills should be assessed during tests and laboratory works.
3. Is able to solve tasks independently and, in case of problems, solve them independently; use MicroStation to draw plans and apply topographic notations to design plans. Competences should be assessed in the performance of independent work and tests.

AutoCad
1. Knows and understands the principles related to the use of the computer program AutoCad in the preparation of graphic materials - oral test.
2. Able to use the main tools of the program and team design - test.
3. Is able to define a task, chooses a design method and tools and develops individual graphic material - independent work.

Part-time studies:
All topics specified for full-time studies are implemented, but the number of contact hours is 1/2 of the specified number of hours

Requirements for awarding credit points

Each part ended with a mark, the end result is weighted average.
MicroStation
All planned exercises must be developed, drawn and credited for independent work and 2 tests must be passed.

AutoCad
The test will be if an individual task has been developed and there are positive results of the conversation about the course content.

Description of the organization and tasks of students’ independent work

MicroStation
1. Independent work: development of individual graphic material, applying the skills acquired during laboratory work and in accordance with the teacher's instructions.
2. Independent work: display and presentation of geospatial data according to the initial data and point coordinates of the surveying of the respective territory.

AutoCad
Within the framework of independent work, the student develops individual graphic material in accordance with the instructions of the lecturers.

Criteria for Evaluating Learning Outcomes

MicroStation
The course mark is formed as an accumulative assessment from the average assessment of independent work (20%) and the average assessment of tests (80%).

AutoCad
The student is able to prove the acquired skills in working with AutoCAD, defending individually developed graphic material.
