Teaching method

Lectures, laboratory classes/computer, project, presentations by students

The teaching methodologies are focused on independent work of the student and practice (hands-on). This work is tutorial for the application of theory to practice remote sensing and digital image processing. At the end each student must be able to propose a project using images obtained by remote sensing revealing knowledge and skills accumulated over the course.

Evaluation method

1 theoretical exam: [25%]
1 practical exam: [25%]
1 project report: [50%[
1 presentation of the project: [pass / no pass].

[According to the FCSH Assessment Standards, the proposed evaluation elements to introduce students in the first class may suffer readjustments, particularly in the percentage of each element.]
