Summary

The subject introduces the methods for digital processing of remotely sensed imagery. The subject has a practical orientation, combining conceptual foundations with a view towards applications. Students are offered a selection of advanced processing techniques for remotely sensed imagery. The course participant manages to choose the appropriate processing method, comprehends how to use the method practically and is able to assess the processing outcomes critically.

Way of continuous check of knowledge in the course of semester

Students are asked about knowledge from areas that they should have already known from previous lectures. Students also work on individual tasks. Tasks are frequently based on understanding of previous, simpler tasks. Student must pass writing and oral exam.
