Two methods are used:
- Expository lectures
- Hands-on lessons: extensive use of software for digital image processing by means of exercises.
In class teaching.
Evaluation Method - Theoretical exam(60%), Practical exam(40%)
1. Concepts and physical principles of earth observation: i) electromagnetic radiation; ii) electromagnetic wave; iii) electromagnetic spectrum; iv) electromagnetic radiation sources; v) interaction of electromagnetic radiation with matter; vi) interaction of electromagnetic radiation with the atmosphere; vii) spectral behaviour of vegetation, water, and soil.
2. Earth observation systems: i) sensor system resolution; ii) satellites and sensors; iii) main applications of earth observation systems.
3. Digital processing of remotely sensed images: i) the image as a data matrix; ii) geometric and radiometric correction; iii) enhancement and combination of spectral bands; iv) arithmetic operations and algebraic functions on bands; v) band transformation; vi) image classification (unsupervised and supervised)
