Course abstract

The Photogrammetry and Remote Sensing course is designed to provide students with the basic knowledge and practical skills to choose, apply and use modern remote sensing and photogrammetry technologies in various situations in their prospective professional activities in surveying, construction, land management, forestry and in agricultural sectors.

Learning outcomes and their assessment

Know and understand modern photogrammetric and remote sensing data acquisition methods, the nature of methods, application possibilities, data processing and spatial analysis.
Is able to orientate oneself in the issues of identification of photogrammetry and remote sensing application possibilities and definition / ordering and realization of work tasks while performing one's professional duties;
Is able to apply the acquired basic skills to work with remote sensing data, using photogrammetry and remote sensing methods and techniques, their application in modern applied aspects and research directions.
Assessment: Written exam, covering the issues of the whole course of the subject; laboratory works and students' independent work.

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

Requirements for awarding credit points

Assessment: 1. Written Exam, covering the questions of the whole subject course, according to the received exam ticket.
2. Test on course theory issues.
Successfully completed and defended practical work tasks:
3.1 Practical work - aerial and terrestrial image processing, 3D point cloud and orthophoto generation using photogrammetric techniques.
3.2 Practical work - processing of freely available (Sentinel) satellite data and generation of relevant products using remote sensing techniques and freeware.
4. Student independent practical work

Description of the organization and tasks of students’ independent work

Students' independent work - using the skills and abilities acquired during laboratory work:
- perform continuous photogrammetric data acquisition with your everyday camera,
- to process obtained data using freely available software,
- draw up a report on the results of practical work in written form (volume at least 6 pages, submitted in electronic form).

Criteria for Evaluating Learning Outcomes

The evaluation of the study course depends on:
1. assessment of exam answers.
2. cumulative assessment of test papers and permanent work of the study course.
A student can get a passing grade for a test or exam if at least 50% of the test questions are answered correctly.
The performance of permanent papers and exam tasks is assessed according to the established 10-point grading system.
The grade of the final exam is calculated as the arithmetic mean of the marks of the written exam and the student's independent work.
