Course abstract

The aim of the study course is to give students the essential knowledge and practical skills to choose, apply, and use modern digital photogrammetry data and technologies in various situations and sectors related to surveying and land management, forestry and agriculture. The program is intended for comprehensive training of specialists of cadastre, agriculture, forestry and other rural areas.

Learning outcomes and their assessment

Knows the methods of obtaining modern photogrammetric data, the nature of methods, applications, 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 photogrammetric 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 total allocated full-time hours.

Requirements for awarding credit points

Assessment of Exam:
1. Written Exam, covering the questions of the whole subject course, according to the received exam ticket.
Completed and defended practical work tasks:
2 Practical work - aerial and terrestrial image processing, 3D point cloud and orthophoto generation using photogrammetric techniques.

3. Student independent practical work

Description of the organization and tasks of students’ independent work

Students' independent work task – using the skills and abilities acquired during laboratory work, a student has to obtain imagery with own consumer camera and process the received data using freely available software; presenting the results in written form (submitted electronically).

Criteria for Evaluating Learning Outcomes

The study course evaluation depends on the written Exam's assessment 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 if at least 50% of the test questions are answered correctly.
The student works and exam performance is assessed by the university established 10-point grading system.

The final exam mark is calculated as the arithmetic mean of the written exam marks and students' independent work.
