| Course objective : | * To understand the process of acquisition and the nature of the information of the remote sensed images in Earth, Life and Sea sciences.
* To know the main types of treatments applied to the remote sensed images.
* To control the functionalities of image processing using typical software tools. |
|
| Prerequisites : | The course intensely exploits the mono and multivariate statistical treatments and the principles of spatial analysis.
Moreover, it frequently refers to the concepts of numerical analysis, matrix algebra and analytical geometry studied during the courses of mathematics.
A certain number of concepts of numerical and mathematical cartography are also exploited. Some softwares tools handled during the exercises of other courses given by the members of the Unit of Geomatics are also exploited.
These notions and the use of software tool are briefly recalled during the practical sessions. |
|
| Workshops : | In the case of the course of Remote Sensing, directed and practical working sessions organized.
In the cas of the course of Satellite Oceanography, only directed working sessions are organized. |
|
| Organization : | The sessions will take place in room 35 located on the 2nd floor of the B5a building. The theoretical sessions alternate with directed working sessions. For the course of Remote Sensing, the practical working sessions begin after the end of the theoretical sessions and directed working sessions. |
|
| Written notes : | The support of the course and directed works consists in a collection of PowerPoint slides, Word documents and extracts of publications and books.
The numeric slides are available in PDF file-format and downloadable from the FTP server of the Unit of Geomatics. |
|
| Assessment : | The evaluation comprises two parts.
A written part, with opened book, consists in solving a exercise by means of a software used during the directed and practical working sessions. The students have more or less two hours to carry out this exercise. This part of the examination represents 50% in the total of the points in the case of the Satellite Oceanography course and 25% in the case of the Remote Sensing course. In this case, 25% of the evaluation is also based on a report concerning the practical working sessions.
The second part of the examination consists in answering a questionnaire in a written way on the theoretical part of the course. This theoretical examination intervenes for 50% in the total of the points. About hundred questions are given to the students at the beginning of the course.
We reserve ourselves nevertheless the possibility of changing the course of the evaluation and the weight of each part during the year. Of course these changes will be carried out in agreement with the students who will be kept by these. |
