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.

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

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 task – by using the skills and abilities acquired during laboratory works, to constantly obtain photogrammetric data with own consumer camera, and to process the obtained data using freely available software; presenting the results in written form (at least 6 pages, submitted electronically).

Criteria for Evaluating Learning Outcomes

The evaluation of the study course depends on the evaluation of the written Exam and the cumulative evaluation of the study course tests and student independent practical work.
A student can obtain a successful mark on a test or exam test if at least 50% of the test questions are answered correctly.
The performance of the student works and exam is assessed in accordance with the established 10-point grading system.
The mark of the final exam is calculated as the arithmetic mean of the marks of the written exam and students' independent work.
