Course developers

Course abstract

The aim of the study course is to provide a theoretical and practical understanding of the content and essence of geoinformatics data acquisition and maintenance, their tasks and the importance of functioning in the national economy. Students will be introduced to the history, structure, functions, classification, understanding of the organization, use, principles, systems, requirements and capabilities of the acquisition and maintenance of geoinformatics data acquisition and maintenance solutions. In practical work, basic knowledge and skills will be acquired to know, organize and use geoinformatics data acquisition solutions and maintenance principles, tasks, system design and construction, in the next areas of professional activity.
