SATELLITE REMOTE SENSING - 2018/9
Module code: EEEM033
Expected prior learning: None specifically advised.
Module purpose: Earth and planetary observation with remote sensing data is playing a key role in the present understanding of natural phenomena, prevention of disasters, resources monitoring, comprehension of origins of life.
Through a series of lectures, seminars, open discussions and “thinking breaks” in class, the module aims to give an introduction to the scientific principles of remote sensing – both passive and active – as carried out by spacecraft. Remote sensing is discussed in terms of instrumentation, missions, products and applications.
IMPORTANT: The Second assessment pattern (100% Weighting for Written Exam) is only applicable to the MSc Short Course Students.

|Assessment type||Unit of assessment||Weighting|
|Examination||2 HOUR EXAMINATION||100|
Students failing a unit of assessment resit the assessment in its original format.
The assessment strategy for this module is designed to provide students with the opportunity to demonstrate the following:
- a basic knowledge of remote sensing principles and instrumentation and a good understanding of the interactions of radiation with the earth’s surface and atmosphere, assessed through coursework and examination;
- a good understanding of Synthetic Aperture Radar principles and applications, assessed through coursework and examination;
- a good capability of analysing end-users requirements for specific remote sensing application and converting them in technical specifications for the design of remote sensing instrumentation, assessed through coursework;
- a good knowledge of basic image processing and interpretation skills of remote sensing products, assessed through examination.
Thus, the summative assessment for this module consists of the following.
· 2 hours closed book examination.
- Satellite Remote Sensing Report: an assignment involving a literature survey on a given application for Earth Observation, the identification of current technological constraints and the suggestion of a technical solution to address present drawbacks. The coursework is set in week 2 and deadline falls in week 7.
These deadlines are indicative. For confirmation of exact date and time, please check the Departmental assessment calendar issued to you.
Formative assessment and feedback
For the module, students will receive formative assessment/feedback in the following ways.
During lectures, by question and answer sessions and discussions
During tutorial classes
By means of unassessed tutorial problem sheets (with answers/model solutions)
During meetings with the module coordinator
By means of unassessed review of the coursework at intermediate steps.
Via the marking of coursework
- introduce the student to remote sensing principles, the physical interactions of radiation with atmosphere and Earth's features;
- introduce the student to the processing of remotely sensed data and the development of applications for Earth's resources management and monitoring.

Methods of Teaching / Learning
The learning and teaching strategy is designed to achieve the following aims:
- communicate knowledge and information about satellite sensors and applications to a wide audience through lectures;
- engage students in the analysis of end-users applications requirements and their conversion in technical specifications for satellite sensors design through exercises in class;
- verify students. Understanding, and give feedback through open discussions in class and tutorials.
Learning and teaching methods include the following:
2.5 hour lectures x 10 week
3 hour tutorials x 1 week
0.5 hour class discussion x 10 week
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
