| Course objective : | 1)To provide students with a complete overview of the possibilities of exploring the environment thanks to spaceborne imagery technologies.
2) To present the main principles that govern the acquisition, filtering and analysis of images.
3) Offer students the chance to try out imaging tools and develop their critical sense with regard to applications in geology.
4) Provide everyone with the necessary technical knowledge to correctly choose the hardware and software tools adapted to a precise problem. |
|
| Prerequisites : | None |
|
| Organization : | The theoretical classes are taught in two-hour modules.
Supervised practical work is done on the computer (max. 3 students per PC) at the end of each theoretical module. |
|
| Written notes : | A copy of the transparencies used in class is available to students on the department's website (in pdf). |
|
| Assessment : | The oral exam will last approximately 1 hour with 30 minutes written preparation and 30 minutes of oral presentation per student. Students choose whether or not to hand in their notes to the tutor.
The oral exam will be on all the theoretical aspects. It will favour a practical perception of the subject (applied theory, the student's ability to use the notions in a precise context) rather than a purely theoretical reconstruction of it (demonstrations, hypotheses, etc.). |
