Remote Sensing

Objectives

The curricular unit targets the fundamentals of remote sensing, the main Earth Observation satellite and satellite image processing methods. The final goal is that the student after completion of the unit will be able, in an autonomous way, to design and implement a project to produce information (e.g. thematic cartography) based on satellite images and classification algorithms.

Teaching method

The course has lectures and laboratory sessions. In the lectures, the instructor uses slides to illustrate the theory. The laboratory sessions consists on the use of a image processing software for deriving a thematic map based on spectral and/or temporal pattern analysis. The course also includes seminars to discuss the socioeconomic benefits of remote sensing.
 
The professor promotes an active and collaborative learning based on real world problem solving

Evaluation method

Evaluation components:

  • Test (individual) - 30%;
  • Practical Project  - 45%. Group project to solve a real problem by using satellite images and an image software chosen by the group. The problem has to be defined by the group. (Presentation and Report);
  • Essay - 25% - The group can choose between two types of essay: (1) socio-economic benefits of remote sensing within a specific theme selected by the students from a list provided by the Professor, or (2) research and development trends in remote sensing (Presentation and Report)

 

Both Practical project and essay should be done in a collaborative way by students organised in groups. The composition of the groups for the practical project and essay should be the same. No individual projects or essays are accepted.

Dates:

  • Test: November 25
  • Essay: December 14 (till noon, i.e. 12 hours in 24-hour clock)
  • Practical Project: December 16 (till noon, i.e. 12 hours in 24-hour clock)

 

Rules:

  • Minimum grade in each component - 8
  • Projects not delivered within deadline are not considered
  • Projects not delivered through platform TurnItin are not considered
